high flow catalyst convertor? sr20det application

[Fenvy]

well since my car is goign to be illegal in ca due to sr20det, I kind of don't need a cat regardless but I think I shouldn't help creating more smog than not having one at all.

So, I would like a high flow catalyst convertor, I was looking at it when I had my integra but now I forgot where I was looking at. Anyone know a good brand for high flow cat? I don't need the flange.

Also, for sr20det with greddy down pipe, what is the optimal piping size for exhaust? 3 inch? so I would probably also be looking at a 3 inch high flow cat?

I was helping my friend doing some work under his integra and dang I saw a 3 feet resonator... can I use something like that on sr20det? he said that's the biggest one he could find and work wonder for reducing unwanted noise.

http://www.summitracing.com has high flow cats in various sizes, without flanges. You can buy the flanges and then weld them on yourself (or have a shop do it if you don't weld).

also http://www.landspeedracing.com sells them for the Sentra SE-R, but it will work on a 240. Just get the same year SE-R. Land speed's cats are expensive though

I wouldn't worry with a resonator. With the cat and a decent muffler, the volume will be very sedate unless you romp the gas. Mine gets sort of loud above 3000, and I'm running a stock cat and an Otto Racing muffler with silencer

Loveless - We sell high flow cats as well, and I can have you a flanged one made if you don't want to have it welded...

3" is perfect for your application.

We also have resonators in 3", but I don't know of ANY that are 3' long... Our biggest is 22".
