exhaust direction
i'll start by saying i've spend lots of time in the archives, 500 exhaust pipe hits and so far can't find what i need. i'm finishing the cat back and i'd like advice on whether the new pipe (2.25) on my 94 p/u should follow the stock path out the side behind the rear tire, or should i take it straight out back. is it true that if i take it straight out back that fumes could be sucked back in the slider rear window? looking for performance, sound is secondary.
thanks for your help.

The problem with going straight out the back is that you have a better chance of pinching it off there. I know at Paragon I scraped the rear bumper coming off of obstacles once or twice but I never hit the area where the stock exhaust comes out. I actually cut mine off after it turns down over the rear axle when I did my ext, shackle, I get no fumes and I have never hit it there!!

I think it pretty tough to get the exhaust into our trucks thru the window unless you have it dump right under the cab or somethin...its more of a prob for 4Runner owners. I've got mine cut off just inboard of the leaf spring where it starts to trun out to the stock location: http://i3.photobucket.com/albums/y74...k/P6070148.jpg
seems to work just fine no resonating or anything

thanks guys.
it's on. followed the stock direction. it tucked up nicely. the flowmaster 50 gives a smooth throaty sound down low with no heavy resonance at highway speed. lets the headers work.
now, about that cam. . . .

i rigged up my exhaust to dump right behind the cab with a turndown. no resonance but it's a 2 1/4 glasspack so it's loud and pops a bit when i get off it. not really the sound i like, i might try a turbo muffler or flowmaster knockoff, and use 2" tube. i'll have plenty of time since i got a defective thorley header

kyle... it isnt a state law its us dot...
a passenger vehicle such as a 4runner or an suv cannot have hte exhuast exit anywhere forward of the rear axle due to safety issues as fumes may enter the cabin... however its ok to have it exit before the wheels on a pickup truck because the exit is behind the passenger cabin....
