2 Mufflers

[RON-15H]

Hey guys

just wanted to advise on my exhaust system:

kokimoto cat back

front pipe

2 mufflers

no dump and i think its a stock cat

i wanted to get my exhuast system updated

i wanted to get a dump or a new front pipe

and i wanted or i heard that if i get rid of the 2nd muffler it will be less restrictive and my car will go harder????

and i was thinking of putting a new high flow cat??

i got a quote and to do this will cost roughly $600

high flow cat and dump and remove 2nd muffler do u think its worth it or should i leave it??? will my car eat more fuel???

the exhaust on a turbo should be as free-flowing as possible for obvious reasons. we do not rely on back-pressure in the system like the n.a. cars which is why the n1 systems from apexi and such are just really a straight pipe from the cat back.

high flow cat would free up air flow, as would no cat. but i'm guessing u wouldn't wanna run without a cat.

n less mufflers = less restriction + lighter = faster car.

i got a cat back.

mines got a small hotdog size bit jsut before the rear axel, then i got the tanabe muffler at the back. my car isnt that loud, least i dont think it is.
