I'd like to (have to) change intake system and exhaust line
wich could you recommend me ??
KN system ?
and exhaust line ???

online shop to buy, shipping to europe ??

Thanks

 

k&n cold air intake or round air cleaner with the k&n filter in it. exause i would use a single in dual out flowmaster 40, with 4' pipes out the back at an angle. i dunno what the french laws are though so research that before makin it loud.

 

Ok Thanks, i will check about the catalyst problem

 

spend money on the exhaust first
and get the sound you like
plus try to get the backpressure at full throttle and 4000 rpm
below 2 psi, where hp gain should be 12-14
over the stock system with a backpressure of about 7 psi.

Avoid a tailpipe length in the 55 to 75 inch range
because it can cause a drone noise at highway speed rpm range.
