EXHAUST ROUTING

[wheelnut46]

While driving to work on Monday my tailpipe broke off right after the muffler. I took it to see a friend who custom builds exhausts and he told me I'll need a new muffler too. OK, so which Flowmaster will I want? Not looking for too loud but want flow for daily driving and towing.
He has a 7 or 8 foot length of 2-1/2 inch stainless that I can have for the regular price. It wont be duals but at least its larger. Currently the truck has a 2-1/2 inch Y pipe reducing to a 2 inch muffler and tailpipe. This was on the truck when I bought it. There is no catalytic converter.
Also, is there a place where this exhaust can dump and NOT flow into the back window when driving? This is a real drag in the summer when its hot and all I have is the door windows to cool the cab. Any help is appreciated.

I have a 91 w/ a TBI 350 ...I have 3" pipes and a Flowmaster 50 ...its pretty mild til you get on it ...then its pretty throaty ...but not obnoxiously....

I have mine routed behind the tires, just under the rear quarter panel. I had a bad exhaust "backflow" problem into the rear with the window down, until I opened the vents under the dash...some have them some don't..but it works for me.

It's 3" pipe- from the header's, through dual cats, to dual flowmaster 50's.....sounds perfect...has a low rumble at idle, but if you get after it, she gets nice and throaty--no BBBBBBLLLLLLAAAAAAAAATTTTTTTTT to it at all..

Route the pipes out behind the rear tires at a 90 degree andle so they are long enough that they stick out about an inch from the body...this works on mine

behind the rear tires facing downward at at 45 degree angle out and back.

Made mine so it dumps out infront of the rear tire, no fumes at all anymore.
