I found a good deal on some used Edelbrock headers and Y-pipe for my Camaro so I decided to go for it.

The headers are 1-3/4" stepped to 1-7/8" with 3" high velocity merge collectors. The Y-pipe is an off road pipe (no cats). The headers have a slip fit collector that should be welded which these aren't. I need to weld them up so they don't drive the O2 sensors crazy. I plan to add cats to the Y-pipe. I'm undecided on the cat back and thinking of:

(1) Keeping the stock cat back and put in an electric cut out in the I-pipe (I already have the electric cut out).
(2) Hooker cat back exhaust.
(3) Keep looking for a good used SLP dual/dual cat back.
(4) Just using the headers and fabbing up a custom true dual exhaust.

Based on my time and finances I'm leaning toward option 1 or 2 but would like option 4. Thoughts or suggestions?

I feel the cut out would be better because you only need them for 1 thing otherwise it is stock sounding or close.

i like option 1. if youre going to do any serious exhaust work then save up and do option 4 whenever feasible.

Option 1 it is.

I have to upgrade the injectors before putting the exhaust on since in cold weather I was hitting 99% duty cycle.

I will be getting the welder soon so buy some 3" pipe and lets get it going. Option 4 that is.
