Re:What size DP / Exhaust
 

i was gonna run...



test pipe, 18" resonator.. and a universal muffler..

should i get a high flow 3" cat instead of the test pipe to help give some backpressure?... im using the stock o2 housing so thats 2.5 i dont know.. what have other ran with a similar setup 2 mine..

my goal is 200whp @ 8-10 psi

Re:What size DP / Exhaust
 

are you gonna use a flex section? I would just go 2.5" all the way back.. 2.5" is good for about 300 whp with an externally routed WG dump..

Re:What size DP / Exhaust
 

yes im gonna use flex pipe at the end of the dp where it connects to the test pipe.. i think ima go 3" all the way just for future upgradability... hopefully it dont spike.. if so then maybe ill get 2.5 dp.. and keep the 3" exhaust the rest of the way..

anyone with a similar setup? let me know what you have...
