I started a thread earlier about my Cat screwing up and causing a rattling noise at around 2000 RPM. So, I was looking for high-flow cats for my Accord and came upon this:

Have you guys heard anything about this? Also, my O2 sensor is welded into the cat because my header doesn't have a predrilled hole for it so will this Bomz Racing Cat be able to have a hole drilled so my O2 sensor can fit in it?

Thanks!

The only other high-flow cat I've seen is the Random one: http://www.lightningmotorsports.com/...technology.htm

I like the Bomz one cause it's cheaper and prettier.

The BOMZ is just a glasspack I'm pretty sure. I was thinking about it in my noob years but would never buy it now...

Do it right and buy a CarSound.

i have a carsound cat. the only difference i have noticed with it on is the car being ALOT smoother at shifts(auto) i have the IHE combo too. my accord had a small pipe (5inches long?) that has the o2 sensor bung on it. its a factory part of the car. it is between the header and cat. that little pipe is the only part of the factory exhaust i have left on my car. maybe i should weld a new bung onto a larger diameter pipe...

:werd:

that is a racecat or testpipe, not a real catalytic converter. get a carsound cat, cheaper and better than random.

Guy at the shop here found me a 2.25" Carsound cat for under $100.

hmm....I think I'll consider Carsound cats, then. Umm...do you know what size I should get, 2.5" or 3"? I have an Apexi WS exhaust and I can't recall how many inches the piping is.

Thanks for all the replies!

get 2.25 inch, that's what i got and i have a apexi ws too. the apexi ws is 60mm or 2.34 inches and your header collector is small enough to attach to the stock cat. so getting a 2.5 inch is a waste since you have smaller pipe before and after the cat.

i can't imagine what a ws + stock cat sounds like, cause this is still damn quiet with the high flow unit.

i feel the same, too quite
