nice car dude.. i have the similar suspension set-up as yours and i love it...
btw, what is the effect of using muffler for turbo car on NA car???
the muffler and the angle look really good...
I've seen it done MANY times. Some people think you lose low end, some people say you gained power. But who the hell knows, unless you're a physics expert?
The muffler outlet is 3 inch, then modified to enclose to a 2.5 diameter. Looks like bondo or something where the piping gets smaller. Works fine to me, I had an apexi n1 muffler before with crush bent pipes. That thing was loud and droned, the hks is more subtle and it's nice to have hks products IMO.
