what exhaust should i get for my IS300??? And will it fit under my car without scraping the ground over bumps and such??? I have a rod millen body kit on it if that helps.

 

I have the 5Zigen Fireball on my IS. It has a nice low deep tone and is not noticeable at idle. It starts to get become noticeable at about 3500 rpm.

Apparently a dyno run netted a 9whp w/this exhaust.

It's not too big and fills the bumber cutout nicely.

 

I have heard good things about the HKS Hiper exhaust. I believe there are some sound clips in the archives on IS300.net. I have not seen any dyno results for the Hipr though.

I'm waiting on my SRT intake and the HKS Hiper will be my next purchase.

 

thats what i have... and a few other things...
i think the HKS Hiper dynoed at 11 rwhp

 

Ticalis, I think i'm gonna get the 5zigen if anything.

The HKS is just too big.
Plus for 200 bucks more...seriously now.

< weight = >speed

 

I got a Zigen it sounds nice... I am happy with it and not as much cash as the Hiper..

 

thanx 4 your help guys. I think i'll stick with the 5Zigen Fireball Exhaust. From what i've heard in this forum, it sounds tight, so thanx 4 your help.

 

as of right now, the blitz nur spec seems to be the best exhaust for me. but i will wait for one that looks close to stock if not stock with extremely low noise.

 

L-tuned has their exhaust out and it dynoed at 8 rwhp. It is carb legal too...
