I'm trying to find a high-flow cat that I can use with my RMR 3" catback and DP. Do you guys know if there's any high-flow cat that I can bolt on without any modification or custom installation?
Thanks

 

ask stealth-wrx to mix u up one

 

Buschur Racing.

 

Does Buschur's cat work with RMR exhaust and downpipe?

 

RMR has high-flow cat. check with them.

 

I'm not sure how fitment will go. Best to call em up, both Buschur and RMR, to see how the piping matches up.

 

We've got 2.5" and 3" High-Flow Cats. We only use Carsound high-flow catalytic converters.

Ours will bolt up to any downpipe and cat-back exhaust granted they can bolt to the stock cat.

 

How much for 3" high-flow cat shipped to California?

 

Do your high flow cats allow vehicles to stay emissions legal?

 

Mark - Call RMR or look on their website under the racing products. They now make a 3" cat. I am not sure about it being smog-legal, but you can ask them. I might be getting it soon (esp. since we have the same exhaust), so I am curious.

I heard the RMR cat is almost $400 though. When I spoke to Rhys about it he said HF Cats are very diffucult to make so they will be expensive. I dont see why they are so hard to make since so many people make them for so many cars.

As for the Ultimate Racing one, and I think the Buschur one too, I heard that they arent true 3" all the way through. Can someone verify this? It's the only thing holding me back right now.

 

For $400, I'd get a test pipe and put a cover that looks like I still have the cat.
