i am trying to upgrade my exhaust system , which brand is better to my XE20 IS350 ?

 

I would go with FSport, but it all depends on your budget.

 

F Sport all the way!!! I have the F Sport and the M2 and the difference in term of sound, and bulid quality is day and night. F Sport also holds very very good resale value and wanted all the times in classified section lol.

 

Thanks for input, Guys. Does F sport exhaust create burbles while slowing down the engine to low RPMS? I mean when you let off the throttle .

 

I think you refer to drone right, very little to no drone. However, in all RPM, you will hear the nicely tuned low frequency sound that give you a sporty driving feeling.

 

The Ark Full catback exhaust (available next month) "burbles" when you down shift...like its supposed to sound like. you will get very little to no droning during coasting on low RPMs.

you wont get that burble with the restriction of the stock pipes/cats and the f-sport muffler.

 

Note that removing cats is not legal in some states such as CA. You might have hard time passing smog check.

 

good point but in california you pay a smog abatement fee for the first six years of its release. then on the seventh year you need a smog check certificate along with your registration fee. so even in cali you'd be good with removing ALL cats...lol. in any case....i know a guy who can "pass" you with no problems everyone should know a guy...

 

haha... how much does your guy charge to pass?

 

just get a muffler delete with a 2" or 1.75" straight pipe and tips of your choice. best 2 bills you will spend...on a car at least.
