Piper Exhaust System 76mm FULL Turbo Back Twin with Sports Cat Astra H VXR

Piper Full 3" (76mm) Stainless Steel Turbo Back Exhaust System with sports cat for Astra H VXR. 

Ideal for maximum horsepower gains, especially on mapped cars. A 3" system produces better flow than a 2.5" system with no loss of torque (having been compared like for like). Manufactured in the UK from high grade stainless steel.

Includes new rubber exhaust mounts. This system includes a limited lifetime warranty on the stainless steel (excludes cat). 12 months warranty against manufacturing defects. Catalytic Converters are warranted for 6 months.

Example Gains:
On a 318bhp cars switching from a 70mm system to this 76mm system saw gains to 334bhp due to the improvement in flow/reduction in back pressure and EGTs.

Silencer Optons:
A- 2 silencers (centre and tailbox)
B - 1 silencer (tailbox only)

We recommend the 2 silencer option. Single silenced option is significantly louder.

Catalyst Options:
This system has a straight through front pipe with no pre cat and is fitted with a main sports cat.

Tailpipe:
The system is neatly finished with an oval K2 Style tailpipe.

Please Note:
Sports Cat is designed for Motorsport use only (not for road use).
Running no catalysts may lead to failing an emissions check and an MOT failure and the EML coming on.This set up may not be road legal.
The Engine Management Light may come on when a sports cat is fitted for Cat System Efficiency Below Threshold (P0420). We can remap the ecu to remove the EML for the cat system efficiency (P0420) error code in cases where the EML comes on for this trouble code.
Cars running 1 silencer may not be track day friendly.

As Used on our 2011 & 2012 Production Touring Car Trophy Race Cars.
