is it possible to have a spintech pro street or pro shoot out with two tailpipes instead of one?

Since your going with the single exit I would say tuck it up high and have it dump behind the bumper. If you can get it just right you won't be able to see the tail pipe and it will look clean. That's what I did with mine and nobody has any idea what I have up in there until they get under the car. That's my .02 though.

But don't you get exhaust gases into the car when sitting still (like at a stop light) that way?

Nope. Also, after reading again my statement is not true. I'm not using a "dump pipe" but more like a huge stock type tail pipe. What we did was make the pipe flush with the bumper in the stock location. If you get down you can see that it sits just below but like maybe a 1/4 of an inch. I never smell exhaust with the way it's setup. Having done this, with the car running in the dirt you can see the exhaust hitting the ground about 1 to 1.5 feet behind the car. I'll see if i can find a pic to show.

Ok, here is one that I found and I drew on the pic to give an idea of how it's setup. Hope that helps.....

I just did. If I can remember, I'll see if I can locate some of the pics I have that show it under the bumper to give you an idea.
