Does anyone know were I can find information on this exhaust?


It says it is a ZEES exhaust but I can't find any information on the internet about ZEES exhaust's.

If you want to go dual your best bet would be to get it custom done. I doubt any US companies will make a dual system for the IS and there's no point in puting on the Altezza exhaust piping since they are totally different engines. You can buy two univeral DTM Style mufflers and get the piping custom done at an exhaust shop. I'm not sure how much those go for but I think the $200 per muffler sounds decent.

If you are going to do it you might want to make sure your mufflers are straight, sometimes they just connect it to anything they can and one of them is crooked

That Dual doesn't look like a True
Dual. Looks more like the single to a wye, to
the Dual.....
A real Dual should come from Engine all the way Back.

Also, that system shows TOO MUCH PIPE under the car for my taste.
Looks sorta like the Old Corvette Pipes...

Maybe a Hanging Problem after a while???

Correct me if I am wrong but the GS uses the same type of setup correct? For a 10hp+ (with headers?) gain I think it is worth it.

Exhausts are about flow...dual or single has nothing to do with it. A single that can flow the same as a dual would be preferable due to weight savings.

dual setup on a single are usually for show cars, because they do not gain any performance, but most likely loose torque because there is not enough back pressure.
