I just got done putting on my 4" straight pipe exhaust...and all i can say is wow! It sounds bad ! Very nice sound inside, and mean sounding outside when revving. I also installed the s & d cold air intake kit. It whirrs loduly under acceleration, and sounds very nice. I think i want a little more turbo whistle instead of sucking noise, but I was afraid to remove the silencer ring.
I now have done 4" exhaust straight pipe back... cold air intake kit.....and removed the silencer ring. god damn does it sound good. i just ordered a #100 plate and then i think i will be done for quite a while until trans upgrades
