Im planing to get an exhaust for my IS 350 but im not sure which one to get?
Im looking for an exhaust thats not to loud but gives me the most hp gain?
I've been looking at the tanabe and the HKS?
So Lexus Pros out there help me out!! Thanks

 

tanabe +1000000000

 

the new f-sport sound great, i got hks high power, she loud, yum

 

The only thing i don't like about Tanabe is loud droning at 3000rpm. So loud!!! Otherwise it sounds great.

 

Hks All The Way!!!

 

Which exhaust would give me the most HP gain?

 

An illegal one. You might get as much as 15 out of the Borla but it has questionable build quality and isn't legal anywhere in the US.

All the 50-state-legal ones will give you about 5-7 hp... and the tanabe will be the quietest of those.

In theory Joe Zs new full exhaust with hi-flow cats would give you 10 hp, and be mostly legal (I doubt it'll have a CARB number though but I could be wrong) but it'll cost you more than double that the tanabe does.... it's a VERY nice and well built system though.

 

F-sport intake + f-sport exhaust sounds the best! 10-14 hp gain
lexus of westminster has a sale right now for summer better than sewell
check it out

 

as far as 'loudness' scale:
1 stock
2 tanabe
3 greddy
4 hks (but hks has a scale within its self too)
5 fsport
(where does borla fall within this scale? probally same as fsport since everyone knows how LOUD borla's are)

as for power... well... these are aftercat exhausts so you'll still have the bottlenecks unless you go the headders/midpipe route...

 

I recall that the blitz was supposed to be coming out soon with a cheaper price right? Also heard that it was quieter than the Tanabe... Anyone know when those are coming out?

 

I personally think the Borla is louder than the lexus hks which i have
its kinda loud but not obnoxious or anything

any questions about this exhaust (pretty sure the f-sport) is extremely similar if not identical, PM me

 

joe z had the blitz but sold it. i have a tanabe and for me that is good enuff cuz i have kids in the back and my wife doesn't even know i have a new exhaust. shhh.. she still didn't find out yet wat is different about the car. If money is not a problem, JoeZ exhaust would be perfect.

 

HELL YEAH, IF I HAD MONEY I WOULD LOVE TO GET JOEZ EXHAUST...I HEARD AT THE JAYS BBQ SOUNDS AMAZING...

 

What about the LMS?
I heard that it has a nice HP gain.

 

get the one everyone is selling here
