I was looking at the airbox on my NA it doesnt look much like you can do anything with it. And what should I do with the exhaust its all stock should I straight pipe it?
Straight pipe will be pretty loud on a N/A. I would try to find one of the factory dual outlet manifolds and downpipes from a gasser. It should be pretty cheap while offering a nice flow increase. Then your choice of an exhaust system, I prefer systems that use mandrel bent pipe.
I got TD manifolds and turbo'd mine. Made a 2" SS down pipe and all the way back. Wish I had gone 2.5" or 3" ;-)
Well I would like to turbo it eventually Thats kind of why I dont want to spend a whole lot of money on the exhaust but the cat and muffler look very bad on there. Im thinking the cat could be having some flow issues. hardly any exhaust making it through even if you rev it. just how loud would it be with a straight pipe?
I have straight pipes on mine.
It does make some noise but not as much as most of the rice burners with there big
mufflers.
