Thanks you for all the great feedback.
They came out really nice, will see how they hold up, just finished my build. I can't take credit for the welds, a friend helped me out with those awesome beads.
@cmitchell17 Gesi also sells just the cores, this way you don't have to cut anything off.
I would love to help you out, but I live in Switzerland, shipping would be to expensive. Any good fab shop in your area should be able to to the work for you.

Only the primaries are round. Secondaries and completely different.

I would probably leave the secondary ones off, I think with the GESI cats in place of the stock primary cat location they would be close enough to light off better and keep the bad smells away.

Yeah will be fine. Mines cammed and after a few mins any gas stink pretty much gone. I had them off for a bit and lord does it stink.

Hence the he reason for getting the new gesi high hp gen2 cats.

Let me know how the CSP headers & the cats work out for you. I’m looking at this system right now.

Got any pics of the CSP headers and 1700hp cats? Not quite sure how they fit a 5" plus body cat under the car where the headers end, space is very tight there.

Cars going in their shop next Monday for the install. I’ll have them take pics.

From my understanding is they had them custom fabricated to fit their csp headers. I asked about the fitment on my kooks and your concern about fitting was same as mine. Apparently the kooks are different then theirs as well as the cats themselves which seem custom made for their headers as well.

Its possible kooks will have some sort of fitment to their header in the future. But for now csp/stainless works beat then to the punch this round.

Correct me if I’m Wrong but as of now gesi just has a generic cat and/or the actual barrel they sell.

My buddy should have his 2" CSPs and the 850hp cats in the next 15-20 days. Will ask him to take some pictures. They are on the way to Jet Hot for ceramic coating first.

Just picked her up today.

First impressions, sounds even better then before. Less pinging sound from headers, slightly even deeper tone also. Seems like the csp/stainless works might be made a bit thicker. Clearance is great around plugs, motor mount and steering shaft.

Here’s some pics.

Any questions just let me know.
