Midlength to Longtube headers is about a 10-15rwhp difference. Much more noticeable if you plan on a bigger motor, or forced induction

I am running no cats into factory mid pipe with an x-pipe welded in into a custom magnaflow axle back. No loss of power. I'm sure a full custom mandrel bent 3in exhaust would be best, but my setup worked for now

Not sure where your budget is but I am very happy with the ARH LT's and their mid pipe. No cats. Very quiet with factory axlebacks, and perfect (for me anyway) w/ GXP axlebacks.

Currently run the Kooks 1 7/8 LT's and Corsa to quiet it down a bit (until I go WOT ). No complaints here whatsoever.

SLP longtubes have a terrible merge pipe from the Cat to the exhaust.

You can run Kooks LT's and their x-pipe (either catted or not) and still tie into your axle back. That's what I run but I'm a solo axle back. I like it loud!

Look inside at the cat when you get them. The 2 1/4" pipe is almost touching the cat element. The set I installed got cut apart and fixed before I would install them.
