Mufflex 4" catback y-pipe fitting question... http://www.mufflex-performance.com/m...tegory_Code=FZ
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.

yes, i just bought the 4" cat back with dual tail pipes and i know you have to cut the end off to mate it up right. i'm doing mine with a 3"/4" flowmaster merge.

That's pretty stupid...
I'll ask them if they'll just send it with a 4" midpipe. If I'm spending $600 on a catback they can at least do it right.

Basically only it was the single out with a 4" magnaflow muffler. LOVED it. then got stupid and jumped on the TD bandwagon and went that route till I enventually sold the car.

Its all in here. I even did the 3.5" on my z28, but it was a clearance nightmare.

yeah there is a vid in that thread i believe. I am at work and cant verify if its the true dual video or not on one of them. I know that the 244/248 cam video is on the true duals though.
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.

Yes, I was going to go with TSP 1 7/8" LT's to the Flowmaster 3" to 4" Y and a Mufflex 4" catback.
I figured it would be as close as I could get to td's without it droning too bad in the cabin

I just got a response from Mufflex.
"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

no, the both vids were of the duals. im just curious about the noise VS running a cutout and a stock cat back.
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

I was going to have it all shipped to a local shop and have them install the TSP headers / FM 3/4" Y-pipe and catback and weld it all up. I just didn't want anything to happen that would make them charge me more money.
