i went true duals and I have noticed a bit more stomp in the pedal...

 

cuttin the y, addin the h and a catback will be good, ru thinkin bout that h-pipe conversion on american muscle. that will work then u can use ne gt catback u want, u will get some hp out of it, not a whole lot but a lil

 

I was thinkin about getin the same set up as you..... how do you like em

 

if ur talkin bout the divorced duals with 40's, i love them, they dont seem as loud now that i have gotten used to them but ne one who rides with me said they are pretty loud n ne one outside the car says they are crazy!!
im gettin rid of my cats when money permitts tho to give me a lil more plus i have a leak so its pretty much a must to fix that, ull like the sound tho
