Hey guys, just wondering if a Mac High-Flow Y-Pipe wil fit behind stock manifolds?

 

not without modifying it, i believe the macs have a ball style flange.

 

Mac does make a Y-pipe specially for stock manifolds. I used to have one on my car before I got headers. The Y-pipe for the headers will not fit the stock manifolds.

 

If you want a Y-pipe, check out the 3" pipe that LGmotorsports (G2 racing) makes. they make the lagest pipe for stock manifolds. You will have to call them though they just put it up for sale and is not on their website www.lgmotorsports.com. I think it was $225

 

Very true but a Mac y-pipe made for mac hedders will fit stock manifolds with a little modifying. i've seen it done and it fit very nice

 

Thanks guys, I'm just selling my Mac High-Flow Y-Pipe and someone was wondering if it would fit their stock manifold setup and I just told them I'd check for them. What all has to be altered to get it to fit?
