Where can I get 4" mandrel bent exhaust pipe peices?

[sixgun86gn]

I think I am going to try to build my own 4" single exhaust for the GN this coming year.I am going to be putting in a 76GTQ on top of a 249" TA motor and would like it to FLOW.

I have thought about maybe just buying a 4" exhaust kit for a deisel pickup and cutting and fitting the peices together.I want it to go out the stock location behind the wheel.If there is not enough room I may do it NASCAR style in front of the rear wheel.

Any opinions on where to get the bends or if I should try the deisel kit route?If so which kit would need the least modifying?

Look up Mufflex performance in New Jersey
They did my exhaust and had all the bends in stock

Thanks OTTO.Did they make it for you or did you just get peices and put it together?Could you give me any idea of how much I will be spending to do this?I am going to do it, just need to know how much it will cost me.

How does yours sound?Does it have a deep idle?I have the ATR 3" duals right now and I love the sound,but I want to increase flow and keep the weight down or at least the same.

I've seen a Mufflex 4" custom exhaust done and I think it was a hack job. And this was on a TR. Just my opinion.

Damn, Ask anyone who has seen mine, THey did a great job, They did peice it together using mandrel elbows and straight pipe.
The sound is awesome, THey used a 4" magnaflo race muffler
THe whole thing installed on the car cost me 650 including a 4" stainless tip
Sixgun, Ill send you pics

Not bad at all.The pics look good to me.Would they have to have my car to do it?I live in Texas.That is a long way from home.
