Best header fitment, and the option to order catless pipes.

[SheepDog]

Just an FYI, both companies are greater Cleveland based, stainless works is in Streetsboro Ohio about halfway between Cle and Akron, and Corsa is in Berea Ohio, a west side burb of Cle and about 10 minutes from my house. Also Ultimate headers, started by the former founder of corsa, is about a mile down the street from corsa.

I was in Cleveland a few weeks ago for a wedding. I couldn't believe how quite it is, no traffic, no lines at stores, no waiting an hour for a table at a restaurant. I was pleasantly surprised. Add to that the costs of houses are like 1/2 what they are here in Denver- I may just have to relocate. lol

Ohio is a fully red state too, so that's a plus

Sounds even better. I'll look into it before I destroy the cats in the future.

I’ve never waiting in line at a store in Detroit either. I have been robbed in a store in Detroit however. Do with that info what you will lol

Catless guys, what is the benefit to running catless? There are cats that support 1200hp. My 68 doesn’t have cats obviously and I reek of gas after I drive it even with the carb dialed in.

Once you go boosted, all that extra fuel can melt the cats. Sure you can get better cats and you can lean out your A/F to protect the cats, but you run the risk of internal engine damage as a result. it's cheaper, less risky, and all around easier to just go catless once you go boosted.

I ran them with my Ultimate Headers LTHs until I blew them out on the drag strip.

Aren’t the cats that can support 1200 hp super expensive (as in $3K-$5K)?

Might be, I’m not sure that’s why I’m asking lol. I know nothing about the catless world on modern cars

I remember reading something about a pair of cats costing over $5K. For that price, they had better be able to withstand an earthquake style vibrations and lava like temps. I’d hate to be the testbed for those, only to find out that they too can and do fail.

Just curious what about running cats further downstream so they aren’t getting hit by such hot EGTs?

It's actually the other way around. When cat protection kicks in, the a/f ratio richens up so extra fuel will cool the cats. Whipple told me their tune goes into cat protection after ~4 seconds of WOT.

That’s a good question. I imagine it would take a specially made o2 sensor harness that’s long enough to reach the relocated sensor bungs. I haven’t searched via google, but I would imagine that someone, somewhere has tried it. You have me curious now, so I’m gonna search to see what I can find.

It's more than just EGT's, under WOT you can be as rich as 11 to 1 and some unburned fuel can get into the exhaust and reach the cats, and once that extra fuel ignites, it can melt your cats. And with the high heat source being right in the cats itself, well you can guess what eventually happens. Moving them down stream will only prolong the inevitable.

That's true, if your tuner knows about it and utilizes that strategy.
