My motor is completely stock and i go 13.20's w/ 4.10's
I use 1 5/8" mac long tubes
2 1/2" off road h-pipe
2 1/2" flowmaster cat back
I believe there is no other way to go.
The hassle of the long tubes is worth the extra gain.
But if you chose shorty's go w/ equal length.
I had motorsport unequals on my old car and wasn't impressed.
I would do headers first.
piece together the rest, and do it at the same time.
much easier.
the h-pipe is a ***** along w/ the o2 sensors. plan on getting new, and make sure you have some good swivel pieces for your sockets(air tools would be great)
