Mufflex y-pipe and 4" Flowmaster exhaust system

This was made for my 1991 Firebird with Hooker Super Comp headers. Designed to clear the factory crossmember and Spohn bolt-on driveshaft loop....was using Random Technologies torque arm and it cleared without problems.

Y-pipe is dual 3" into single 4" design. After merge, it follows factory routing in 4" mandrel bent pipe, up over the axle into a 4" Flowmaster muffer. There are O2 bungs welded into both sides of the y-pipe.

Going with duals so no longer need. I live in NJ and will not ship this. I will meet up with buyer within reasonable distance.

Mufflex charges $937 plus shipping (as per their website) and the Spohn driveshaft loop is $89.

I am asking $450 or best offer for the whole package.

If you have or are thinking about getting Hooker Super Comps, this is the complete system you need.

I will try to get pics of later of the entire system.

Re: Mufflex y-pipe and 4" Flowmaster exhaust system

Honestly, shipping would be over $100 or more because from the collector flange back to the axle is all one piece.


I would rather sell locally unless you are serious about covering the actually shipping and packaging costs.

Re: Mufflex y-pipe and 4" Flowmaster exhaust system

Cut it off after the y pipe? I would be interested if you would ship it. I don't need the t pipe any ways cuz I run Ed quays and the y pipe won't fit.

Re: Mufflex y-pipe and 4" Flowmaster exhaust system

I'm interested, curious if they would bolt up to the set of Hedman's I have. We're not too far from each other either.

Re: Mufflex y-pipe and 4" Flowmaster exhaust system

Let me get a pic of the whle system up and then you can draw lines where you would like it cut.

Of course, if I am going to cut the system to ship it, full payment is expected before the sawzall gets plugged in.

Re: Mufflex y-pipe and 4" Flowmaster exhaust system

To the Hedman headers....I am not sure of the orientation of the flanges or the spacing. I do not want to tell you they would fit only to find out they wouldn't.

All I know is that the system does fit Hooker Super Comps because they are on the motor now.

Re: Mufflex y-pipe and 4" Flowmaster exhaust system

Would you be willing to throw the intermediate pipe in for a pic?

I need to know how far it goes up to the front to see it sticks past farther than my bmr torque arm.

Re: Mufflex y-pipe and 4" Flowmaster exhaust system

It will the not fit back in as i have the th350 and spohn torque arm in there. The L on the crossmember hangs too low. The intermediate pipe was deigned to clear stock crossmember.

Re: Mufflex y-pipe and 4" Flowmaster exhaust system

Does this clear the factory panhard support brace? I noticed you have the one that lowers it.

So for the questions. Don't wanna have to mod a bunch of ****.

Re: Mufflex y-pipe and 4" Flowmaster exhaust system

It does clear the stock location panhard rod. I was going to run the th350 with a jegster t/a and have true duals fabricated. With the dropped panhard rod, it would give more room. However i am just going with duals that dump before the axle now as it has become a track only car.

Re: Mufflex y-pipe and 4" Flowmaster exhaust system

If it will help you, I can attach the rear part of the intermediate pipe and bring the front up as close as I can to show where the pipes would go.

Let me know before I take the over-the-axle part and muffler out this weekend.

Re: Mufflex y-pipe and 4" Flowmaster exhaust system

intermediate pipe goes right up to the collectors on the headers. If you have Hooker Super Comps...this bolts right to the flanges and is a complete exhaust.

Re: Mufflex y-pipe and 4" Flowmaster exhaust system

If you wanted to cut it off after the y pipe/where the 4" starts that would be good with me. I would need a custom y pipe anyways.

What would your price be for the y pipe back setup shipped to 48875?

I'm really interested in this!!

Re: Mufflex y-pipe and 4" Flowmaster exhaust system

Took pics....trying to find the cable to download them. Let me look into the shipping on the y pipe and over the axle pieces separately. If that works out i will definately separate.
