Since the only Headers available for the 3.1 are not smog legal...Will having an exhaust shop fabricate a performance Y-Pipe be worth it? Big Gains? Smog Legal? Any fittings or sensors in them? Ground clearance problems? This will connect to a high flow cat and a catback system.

 

I was thinking of buying this

What does "enters in to 3 inch collector"? Does that mean the inlet size of the cat needs to be 3 inchs? Is that y pipe smog legal? Will that fit in to stock exhaust manifolds?

 

The best source for these questions...Try asking MAC yourself. Even the description on their stie doesn't have any more information than Hawk's. Make sure you mention you have a V6. Let us know what they say.

I emailed them with all my questions...Will post them up once I get a response

 

90% chance that's for the vee-ate peeps. 3" collector , yeah, get a ca w/3" diameter.

Never heard anyone ask if a y-pipe is smog legalbefore,..... where are the o2 sensor(s) on a 3.1 anyway???

 

For What Its Worth, I picked up my Y-pipe from a local "real" auto parts store (not a Pep Boys) back in 1996 for $180. It was mandrel bent, made by AP. Any "real" auto parts store should be able to dig one up for ya.

 

Yeah so they replied V8 engines only...Tom,wat store should I go to to pick one up? did u notice a gain with it? Can it connect to stock manifolds?

 

Redraif had a muffler shop fab hers up (for PF &E headers) out of mandrel bends, and add the bungs for the stock O2 and a wideband O2 for tuning.
