DP has two cats Biggest restriction is from thereAny1 can tell me how many and where are located the cats in stock exhaust?
I know there is one in downpipe, but where are the rest? Which one is the biggest/most restricitve?
Those two only..Oh
Any others or just those 2?
Ok so uncatted downpipe could cause problems on smog test probably... but also should make turbo spool faster.Those two only..
Other exhaust system parts are a resonator and a muffler
CorrectOk so uncatted downpipe could cause problems on smog test probably... but also should make turbo spool faster.
On the other hand muffler delete just for louder sound shouldnt affect emission tests, I guess..
