Really worth going to a 3 inch Y over the Mac 2.5? With that shitty looking Mac y-pipe outta the car, it really looks like a POS. I am thinking that with a set of ported Macs and a custom 3 inch y-pipe, I could pull some Longtube power gains out of them no problem....

Re: Really worth going to a 3 inch Y over the Mac 2.5? I'd only bother w/ a 3" y-pipe if you're pushing some serious power. The 2.5" y will flow really well up to a point. (somewhere around 430+ RWHP) It would definitely be worth replacing Mac's crappy collector w/ a Flowmaster unit, though.

Re: Really worth going to a 3 inch Y over the Mac 2.5? I have decided to keep my 2.5" Y-pipe. I will be getting a 3" Flowmaster collector, however. I decided to use the MAC Y simply because I don't plan on doing heads (want a T1 though) so I figured it would flow well enough for what I am planning on doing. I won't be running cats either so that will help out.

Re: Really worth going to a 3 inch Y over the Mac 2.5? Keep the 2.5 y and add the FM Collector to it.
Cut all the ball flanges off and your done.
I tried Dyna stepped headers over my ported Macs and FM Collector mod and lost hp below 5000
Macs r great!!

Chris,
Who's car was that? I know of one 422 setup here that did push those numbers, and then had a 15-20 RWHP jump when switched to the Dynatech stepped headers.

Re: Really worth going to a 3 inch Y over the Mac 2.5? I'm running a 3" Y, but have never ran the 2.5" for comparison. Sorry, I guess I'm no help. <img src="images/icons/confused.gif" border="0">
