which exhaust is better?

The HKS is only a tail pipe while the JoeZ is a full catback so they can not really be compared
The HKS cost twice as much as the JoeZ
There is not much information on the HKS, only one person on CL has it so there is no mean to compare them

only tail pipe? you can buy a Cat-Back + "X" pipe if you want. it cost about 1000k on hksusa.com
32023-AT001 LEXUS IS F 2008-2010 ; SUS304 Rear Sections -2995$ and if you want cat back 33004-BT001 LEXUS IS-F 2008-2010 ; Center Pipe (eliminates secondary cats) For use with Stock and HKS SSM / OFF-ROAD USE ONLY- 975$

Greddy is in the process of making one, also. Maybe you should wait for that....?

I agree... HKS sounds beasty.. like it's going to swallow u whole.. but very pricey... Joe Z i believe is the best bang for the buck... also top notch craftsmanship from what i've seen... couldn't afford either kit, but happy w/ Magnapacks for now...

If you don't care about how much $ is, then go with the HKS. It's rare and sounds like a beast. But if $ matters, go with the Joe Z. You won't be disappointed with the Joe Z.

I love my Borla. Get nothing but compliments, matter of fact I had a cop follow me to a gas station and tell me that it sounded 'Sick'

Joe Z or ISSForge is better. HKS for the price not worth it but if u have the money why not. it does sound nice, now if only they release some dyno numbers cuz they never did release them. just remember the HKS is not a true dual exhaust.

If you dont mind. Can you post pics? Of the borla..

ISS Forged, FTW!

I was running the stock exhaust without secondary cats and no mufflers before. I recently installed the ISS Forged system. It is way louder than my previous set up. Probably due to it being dual all they way through, no resonators and the dual mufflers on each side are straight through. Feels like a good amount of power increase along with the Takeda intake I am running with it!
