Basically a ecu that has been mapped to cams and sports exhaust/decat.Then changing this for a standard exhaust I know you will loose some bhp. But will there be an issue with back pressure considering the standard exhaust also cat back on being more restrictive. ie running rich, overheating, running like crap... ???????? ________________________________________ Silver 6 |

I doubt you will notice much apart from not having bleeding eardrums  more often than not you'll gain mid range torque. ________________________________________ need a part number? get on here - http://public.servicebox.peugeot.comBring on the Trumpets. |

At worst you will lose bhp. IT shouldn't be too big an issue. What about a quieter aftermarket exhaust to get the best of both worlds? ________________________________________ Ex SC-6Now in a Megane R26 |
