Hey guys im bout to upgrade the exhaust on my 2002 sti ppp
just wanted some advice before i part the cash...i want loud as the car aint driven daily and i love LOUD Impreza's
heres what im thinking
already has catless dp, and ppp cat (i think) so was thinking of getting a 3" cat back cobra race tube system just wondering what the difference between the resonated centre and non-res centre would be?

and would the car need a re-map after doing this mod?
thanks

 

Definately needs mapping. Had to get my bugeye mapped when I changed from a APS 3 inch system to a APS 3.5 inch decat system. It is loud if I open the tail pipe bung fully. Have not been able to get the thing out yet so don't know how it will sound then. Will try to get a link up to mine on Scoobyclinic RR.

Hope this works.

 

I'd say go for a Nur spec, lovely and loud.
