If you're getting two cutouts I would put them before the cats; putting them after the Y doesn't help unless you have a really restrictive muffler on it.

It's not going to help at all after the Y if you already have SLP exhaust, probably wouldn't even get much louder (besides in car noise from dumping under the body).

Lol you know now that you said that I don't think I'm even gonna get them now. Sound like a waist be good for a show car to open it up for some noise.

Hey just wanted to chime inn - I have the NEW SLP Headers with y-pipe & cats with the Powerflo catback It`s really a nice system concidering I wanted to keep things legal with emissions . I have only slightly scraped once since its installation and it is allot louder/deeper sounding with the headers not crazy loud ( until you floor it ! ) but you will notice a difference , hope this helps .

That's sounds nice but, WITH ONLY AT 12HP GAIN IDEA RATHER GET THE 1 7/8 AN GAIN 25HP. I want it loud so WOT won't be a issue.
