What kind do you have, how much performance gains do you feel.

Anyone modify the stock exhaust with good results?

Anyone remove the resonators with good results and sound?

Tanabe sound good especially after the break in period when it seems to sound a little deeper. If I had the patience I would have waited until Borla came out with their's but I don't regret the choice that I made.

Does anyone know if there will ever/if there can be an aftermarket exhaust system that is silent, something that sounds nearly stock?

Why would you prefer the Borla?

Is the Borla system going to remove the secondary cats? If not they are going to have a hard time being better than Tanabe.

Anyone know how to compare the Tanabe vs the LMS? I loved my Tanabe on my old IS300, but I am open to suggestions on the new IS350.

Hay everone I am new at this place. I just got a new IS350. I had a g35. Just wondering if anyone knew any good web sites to order an Exhaust for my 350

If You Want To Orderd Tanabe Then Order From Option Imports
It Took Me Almost 2 Mnths To Get It But For 552 Dollars Its Worth It

LMS removes the cats so if that conflicts with your state regulations then that could be a problem

where are those, I know we have 2 right by the headers, but I only see resonators after that. Where is the secondary.

how much louder is it compared to stock??

do you feel a power difference??

any dyno numbers????
