Well my cat is getting clogged up im wanting to know whats a good downpipe for my lil 3.4 im going to go dual magnaflow in the fitire so want a good downpipe to help it out... Any help is appreciated... The car is a 01 monte 3.4 thanks..

 

Part numbers will help if possible

 

Anybody?...

 

I would have chimed in earlier, but for a 3400, I'm not sure. I would have recommended a ZZP Downpipe with high flow cat, but I did not see one offered for a 3400 (just the 3800).

Give it a little time, you posted this thread yesterday. I'm sure some of our 3400 guys may have some advice.

 

milzymotorsports.com should have downpipes for the 3400

 

Well i have time now i gutted out the cat so im good for now..
