Mufflex 4" catback y-pipe fitting question...
Is it just me, or is that a 3" or 3.5" pipe where the midpipe should plug into the Y pipe? What would you do if you purchased the 4" Y pipe from their site? Just cut it off and weld in a bit of 4" pipe?
I'm confused and Mufflex hasn't responded to my email yet.

also are you going with a flowmaster merge(or similar)? if not, you need to.

Its all in here. I even did the 3.5" on my z28, but it was a clearance nightmare.
That magnaflow was SUPER smooth. Pretty tame when i had a 236/238 cam. It was REALLY deep sounding though. Which was an awesome bi-product.
I figured it would be as close as I could get to td's without it droning too bad in the cabin
"We custom tailor each kit for the application .If you have our LS1Y-3 or any other Y with a 4'' outlet let us know when ordering and we can put the correct inlet on the kit."
I think I like these guys
would a setup like this **** off the neighbors ALOR, or just a little?
No **** thats pretty much a quote. Its a 4" pipe with no way to slip it over or in another 4" pipe you have to make an adapter or coupler yourself.I told them to add 4 inches and swedge it out and cut some some relief slots.. they don't care to do that.. the only reason I use it is its the only 4" catback. Other than that I think the company sucks for not making a product you can directly bolt on. I might have one made myself by a local shop that has a mandrel bender and then market it.. wont be any worse than what out there right now
