I took the stock cat back off and had an exhaust shop make a flange to bolt on the ddm test pipe an ran it to right in front of the back driver side wheel an its all straight pipe
that's where mine is. word of advice, take that black cable and secure it to the underside of your car with heat reflective tape. that's your e-brake cable.
Shouldn't cost to much. It's a flange, a bent piece of straight aluminized steel and two hangers. Looking forward to hearing it when you have some spare time. Also, how's the sound level for you?
My buddys dad owns an exhaust shop so he hooked me up an did it for free and the sound level is just right for me but i might out a resonator on after I get my catless o2 housing depending on how loud it is.
Can't beat free! It's pretty loud with the cat-less down pipe and most people have chosen a resonator. Eric picked the 18" Magnaflow for his set up and loves it.
