I have qtp's on my Duster and YES you will get peoples attention!!!! What's strange thou is open them up and feel how much exhaust still goes out the back--Steve
Yeah, I noticed that, especially at idle, probably about half and half on flow. I was surprised how loud it gets when just cracked open a little as well. It's also surprisingly quiet when just cruising, even with them wide open. Tap the throttle just a little though and you'll know if they're open at all. Love the sound it makes on shifts, nice little crackle and pop.
