Has anyone done a custom quad tip exhaust on the 3rd gens?

 

Sewell currently has the TTE exhaust..

 

ISS Forged can build you one. They have a model originally made for the ISF which should give a 30-40hp boost if you custom build it for the GS460. They're prices are reasonable.

 

really , can anyone post pics of one thats already installed, i will like to see pics

 

You may want to search if no one replies.

Since I was curious, I found a couple for you.

TTE exhaust - sold by Sewell - has Lexus factory warranty:

I seriously doubt it gives you 30-40 hp boost. Most exhaust systems upgrades give minimal to no hp gain.

 

That's true of axle-back exhaust systems. However when you start replacing midpipes, eliminating secondary cats, etc. you can get more power.

You can see here dyno results which show 30+ hp gains on ISF. Obviously on 3GS it would be smaller since you are boosting of a smaller base.

Looks like crap IMO

 

Interesting username. Are you faster or slower than Captain Slow?

 

The user name is just one I've been using for years and on every forum I'm signed up on. I've owned everything from a 450whp MR2, 640whp drag Civic, 750whp Supra (pic in avatar) and now a 07 GS350 as my daily commute vehicle.

 

Do you have plans to get the GS350 to the impressive horsepower levels of your previous cars?

 

Now Batman play nice lol.

 

LOL. No seriously I want to see guys tune these engines. I can't wait to see whether Designo pulls it off. There has to be a way to boost the hp.
