There's very few if any of these state side, so you'd be in rare company if you get them. Careful though, they're loud and may be unreasonable for street use, but if you have bad hearing like me, who gives an f[][][].
Are you sure ? Here's the pic for the header and the stock cat.



I think you must be mentioning that the 70RR exhaust will not be competable with the stock cat correct ?

My bad, you're right.

I was citing the information I acquired while researching from the 70mm J's exhaust and header, not the other diameter options.

Sorry about the misquote, no egos here.

so if i get the j's header now but buy an amuse exhaust later, it wont fit onto the car before the exhaust is purchased? if i read my information correctly, the amuse r1 is 9 lbs n the dual is only 15 lbs. i think i can sacrifice the 6 lbs for a lil looks and a bit less noise. doesn't the amuse come in 70mm as well now if i rem. right someone posted their 70mm j's header n the 70mm amuse exhaust dyno graph compared to his mugen header etc.

The J's header will fit to your stock cat and stock exhaust. So if you buy the Amuse exhaust later, you will be able to bolt it up to your stock cat.

Amuse does make the R1000 which is 70mm header back exhaust.

The dynoplot I post before was with T1R 70R exhaust with J's Racing header.

oh i see. so i am assuming the R1 would produce more power then the t1r? i dont think ima get the r1 due to the noise level of it. Doesn't the R1 come with a dual version that isn't as loud? I will msot likely put a amuse test pipe on it as well.

PS. isn't a 3" exhaust to big for an NA car? wont it cause you to lose power? n if i get the dual amuse is that 3" as well which would make it worse then a 3" single? sorry these are silly questions.

The R1 titan dual sounded as loud as the R1 single. I don't know how's T1R compare with Amuse R1000 but the price will be the biggest difference. T1R is SS and Amuse is Ti so they are very different in quality as well.

70mm not equal to 3 inches. 70mm equals 2.75 inches.
