EML lights may activate after removing the standard second O/E catalyst. An ECU Re-map is recommended to correct this problem and stabilise all power increases. This primary cat back exhaust includes a H-pipe section to combine and equalise the gas flow giving a sportier exhaust note. Please Note - This performance exhaust retains the use of exhaust valves. When switching drive modes (e.g. Normal to Sport+ mode) your exhaust tone will continue to swop from quieter to louder tones as before. Fits to pre-PPF vehicles only. Requires 2 x BMW gasket - part number 18307851168 - all other relevant gaskets and fittings are supplied. Press Release Keen to make a step above and differentiate from the competition, Cobra Sport have used their extensive experience and use of new exhaust technology to create a product which truly stands out in the aftermarket performance market. The Cobra Sport research and development team quickly made the decision to base the new M3 exhaust systems on 3" (76.2mm) T304 grade stainless steel pipework. The larger diameter 3" pipework enhances the capabilities of the 3.0 litre twin turbo straight-6 engine and utilising advanced gas flow design, allows for substantial performance improvements. The M3 development has been based around a valved cat back exhaust with the addition of a secondary de-cat (catalyst bypass) exhaust upgrade. The cat back exhaust includes a centre H-Pipe section, designed to mix and perfectly balance gas flow from both sides of the engine to increase power, improve flow efficiency and enhance the exhaust tone. Extensive road testing was undertaken in order to ensure there was no resonance or exhaust drone in the cabin throughout the rev range in all drive modes. The sound of the new Cobra Sport exhaust boast vastly improved tonal characteristics, with the new exhaust offering a deeper more aggressive sound when under full load. The Cobra Sport exhaust incorporates a pair of exhaust valves designed to utilise the existing valve motors , enabling continued use of the M3 drive modes to adjust the dynamic of the exhaust. In the comfort driving mode the valves remain shut forcing the gas flow through the flow optimised rear box, creating a finely tuned exhaust note for a sporty but unobtrusive sound track for everyday use. With the valves open in Sport and Sport+ mode, the gas flows through all 4 tips creating a highly aggressive sound track. Cobra Sport Sales Manager Matt Thomas commented, "Building on an existing first class reputation in the BMW tuning market, we're excited to be adding the Cobra Sport sound and performance upgrade to the stunning M3. Power testing the secondary de-cat and cat back system revealed an impressive +21.25bhp and +9.2lb-ft of torque. The free flowing 3" pipework and optimised exhaust technology opens up huge potential for M3 owners looking to increase power whilst also obtaining a pitch perfect exhaust tone." Cobra Sport have improved the styling of the BMW M3, creating a noticeably enhanced and balanced look to the rear of the M3 with a choice of quad 3.5in (88.9mm) inward rolled baffled or inverted highly polished stainless steel tailpipes. For those looking to take the style upgrade a stage further, upgraded ceramic coated matt black 'Blackout' tailpipes are available.

Cobra Sport performance exhausts enhance the sound, looks and quality of your vehicle giving you the ultimate driving experience. Our sports exhausts range is fully guaranteed to give you assurance of our quality. This Nissan Juke Nismo performance exhausts is made in 2.5"/63.5mm pipework and fits from the secondary cat section backwards (Cat-back), this exhaust replaces the centre and rear sections. This exhaust has a choice of 4" (101.6mm) and 4.5" (114.3mm) tailpipe options including a choice of carbon fibre tip options. Please note: Does not fit 4x4 CVT model, please see alternative listings within the Juke category. All relevant fittings and gaskets are supplied. Press Release The hot compact SUV market is one of the fastest growing segments in the automotive industry as they provide the perfect blend of hot hatchback fun whilst offering the feeling of being in a full sized SUV. Nissan pioneered the hot compact SUV by taking their popular Juke, and turning up the heat. The result, a turbocharged 1.6 litre engine with over 200BHP and a sub 7 second 0-62MPH sprint, figures which will frighten hot hatchback owners.  Whilst these healthy performance figures make the perfect recipe for the ultimate hot compact SUV, the Nissan Juke Nismo is let down by its standard exhaust system, which is muted from the factory, limiting the character you'd expect from a performance SUV and resulting in a disappointing drive.  For those who want to enhance the sound of their Juke Nismo, Cobra Sport has the solution with their performance exhaust range.  The Nissan Juke Nismo performance exhaust configurations are as follows: Primary Cat Back - Pipework attaching to the primary catalytic converter, including the secondary de-cat and replacing the centre and rear sections. Secondary Cat Back - Pipework fitting from the secondary cat section backwards, replacing the centre and rear sections. Secondary De-Cat - Pipework fitting from the primary catalyst to the factory fit centre exhaust section, replacing the second standard catalyst. The 4,000rpm static sound testing revealed a +7.8dB increase when equipped with Cobra Sport's primary cat back performance exhaust system. Like all Cobra Sport exhausts, the Juke Nismo performance exhausts are TIG-welded from high-quality T304 stainless steel and the mandrel-bent pipework has been developed in 2.5in (63.5mm) pipework, allowing for a smoother rate of gas flow for improved power delivery and a noticeably enhanced exhaust tone. Cobra Sport have improved the styling of the Nissan Juke Nismo, creating a noticeably enhanced and balanced look to the rear of the car with a choice of dual 4” (101.6mm) and 4.5” (114.3mm) slash cut highly polished stainless-steel tailpipes. For those looking to take the style upgrade a stage further, upgraded carbon fibre tailpipes are available.

Fits - 1.4 TSI ACT FR (2014-15) 3 & 5 Door Models Cobra Sport performance exhausts enhance the sound, looks and quality of your vehicle giving you the ultimate driving experience. Our sports exhausts range is fully guaranteed to give you assurance of our quality. This Ibiza FR 1.4 ACT performance exhaust is made in 2.5" / 63.5mm pipework and fits from the front pipe / catalyst backwards (Cat-back) these exhausts replace the first silencer, centre and rear sections. The resonated sports exhaust includes the centre silencer and has a subtle but sporty tone. This exhaust is also available as a non-resonated version which is a louder option as it excludes the centre silencer and therefore, has a sportier exhaust note. All relevant fittings and gaskets are supplied. Press Release Enhancing the driving experience via a combination of power, weight, styling and acoustic tone is always top priority on the agenda when engineering any exhaust system at Cobra Sport and the system which has been developed here certainly ticks all of the boxes. Cobra Sport's experienced engineers were able to design an exhaust upgrade which balanced the need for improved gas flow without sacrificing back pressure. The results speak for themselves and certainly boost the car's credentials. The Cobra Sport exhausts for the 1.4 ACT Ibiza FR benefit from all of the usual Cobra Sport refinements with mandrel bent, TIG welded, grade 304 stainless steel used throughout the systems as standard. You can therefore be assured of only the best quality in a Cobra Sport system. Matt Thomas, Sales Manager at Cobra Sport says "We are very excited to have developed a cat back exhaust for the 1.4 ACT model. The new Cobra Sport system greatly improve the exhaust pitch and tone and add the sporty edge which was missing from the factory system. The non resonated cat back system offers the most dynamic upgrade recording a sound level of 84.8dB in the 4,000 rpm static test and is the exhaust configuration which perfectly achieves the sound we were looking for with this model. The resonated cat back exhaust upgrade includes a centre resonated section designed to reduce the sound levels and provide a purposeful but unobtrusive pitch perfect sound quality which in no way interferes with day-to-day drivability of the car." The styling of the system is finished off with a choice of twin 3" tailpipes in a highly polished inverted or inward rolled T304 stainless steel finish. A third option for a 5" x 3" oval slash cut tailpipe is also available for those looking for something a little different to compliment the Seat Ibiza aesthetics.

Fits to standard (Pre-PPF) M2 Competition exhaust. Fitment is for motorsport and off road use only. (Requires 2 x BMW gasket - part number 18307851168 - not included). Cobra Sport performance exhausts enhance the sound, looks and quality of your vehicle giving you the ultimate driving experience. Our sports exhausts range is fully guaranteed to give you assurance of our quality. The Cobra Sport catless turbo downpipes produce a deeper exhaust note and allow the turbos to spool quicker for sharper throttle response and power delivery. Matched with a re-map, this part allows for significant power improvements. This BMW M2 Competition performance exhaust is made in 3"/76.2mm bore pipework and replaces the primary catalysts (Cat Bypass). This de-cat exhaust version is sold for motorsport and off road use only worldwide. EML lights may activate after removing the standard primary O/E catalyst.

Requires 2 x BMW gasket - part number 18307851168 - all other relevant gaskets and fittings are supplied. Press Release Delivering an even harder performance edge to BMW's brilliant F87 M2 is the new valved 3" (76.2mm) Cobra Sport performance exhaust. Both Cobra Sport's Technical and Research and Development teams were involved in the planning and preparation that went into the product testing and development of this new exhaust system to ensure the correct balance between sound, aesthetics and power improvements. The new Cobra Sport Exhausts for the M2 are based on 3" (76.2mm) diameter pipework for improved gas flow and to open up opportunities for performance tuning. The T304 stainless steel pipework is CNC mandrel bent and benefits from advanced manufacturing techniques and superior TIG welding procedures to produce a superlative finish. By including the exhaust valve, the new Cobra Sport performance exhaust systems offer the best of both worlds continuing to utilise the built in BMW drive modes. With the valve closed the gasses are directed through the entirety of the optimised rear silencer ensuring a subtle but sporty exhaust tone suitable for everyday driving. In sport mode the valve opens allowing gasses to flow through and exit both outlets of the silencer increasing flow rates and sound levels. The result in sport mode is a much deeper exhaust tone than standard which becomes highly aggressive when under full load with a trademark crackle on overrun, completely overhauling the driving experience. The design of the back box was tweaked a number of times to ensure there was no resonance or exhaust drone with each layout being extensively road tested to find the optimal design. During the same process the exhaust sound was optimised with the final system adding a subtle +4dB on the track test whilst completely overhauling the tone upgrading the car to a truly stunning sound track. Cobra Sport Sales Manager Matt Thomas commented, "The BMW M2 is a real enthusiasts car so we were keen to create a system which suits everyday and full track use. By incorporating the valve, we have been able to cater for both however having heard the exhaust in Sport+ mode that's the mode we expect it to stay in permanently! Matched with the Cobra Sport Sports Catalyst or De-Cat downpipe to create a full turbo back exhaust upgrade, huge power increases are possible with a re-map at one of our tuning partners." The Cobra Sport's quad exit exhaust system benefits from a choice of twin slash cut and angled 88.9mm tailpipes finished in either original highly polished stainless steel or upgraded to our Carbon Fibre tailpipe option.
