It's supposed to make quite a difference. Mike Rizzotti added a second to his 3.5 system as well and liked it. I'll probably go with an offset inlet oval since my only muffler is where the cat would be and I need to angle that rear muffler straight for the proper look. :biggrin:

Re: Comfort comes home-Project Lexus GSX
 

I think you'll like the second muffler. About two weeks ago I added a second bullet muffler to my exhaust, put it in right where the car would go and the original one is in the back of the car. From the outside the car is quite a bit quieter, but from the inside at a cruise on the freeway it is an amazing difference. Completely night and day. Doesn't seem to have affected power at all either.

The additional muffler made a nice difference on Scheides' car, its not much louder than my Magnaflow muffler.

Re: Comfort comes home-Project Lexus GSX
 

Finally getting around to updating this thread. Project stealthy exhaust is well under way!

Re: Comfort comes home-Project Lexus GSX
 

Stockish tips, but in 2.5" ss.

Re: Comfort comes home-Project Lexus GSX
 

Damn, I've been waiting to see that setup since I dropped off your ball hone!

Re: Comfort comes home-Project Lexus GSX
 

I like that!

Re: Comfort comes home-Project Lexus GSX
 

I should mention that I put a Magnaflow second muffler in where the cat goes several years ago, it made a difference, but this new Vibrant muffler in addition should really quiet it down. I also just put in the last set of EVO3 lower 5th gear set, so that should get rid of some of the cruising drone as well.

Got the FP Green sitting on the shelf waiting to go in, this is one of the final pieces of more or less duplicating my old EVO set up on the GSX. Big brakes are next. :D

Just got a bunch of brackets and underhood stuff back from Powder Keg, as well as my RPF-1's. I hope to be driving it this Sunday if it's nice out.

Re: Comfort comes home-Project Lexus GSX
 

Looks great. I'd like to hear it(sometime) when done.

3" correct?

Re: Comfort comes home-Project Lexus GSX
 

^X2.

That looks awesome!

Re: Comfort comes home-Project Lexus GSX
 

Yes sir.

Re: Comfort comes home-Project Lexus GSX
 

What Brake setup are you going with? Cobra, Outlander, evo?

Re: Comfort comes home-Project Lexus GSX
 

VR4 calipers and Cobra rotors.

Re: Comfort comes home-Project Lexus GSX
 

Well, a few updates.

-The new muffler didn't quiet it down as much as I thought, but just enough to realize I have a hole in the downpipe flex section. Time for a new one of those.

-Added the Evo3 5th gear, apparently one of the last available in the country, thanks Tim Zimmer. This might be the best mod I've ever done, 3000 rpm at 75 mph on the way to C&C this morning. No more drone.

-Noticed an annoying hum, time to replace one of the rear wheel bearings.

-Bought a super nice aluminum 4" CAI, but doesn't fit with my short route piping, this will be up for sale shortly. In it's place I was able to use the carbon fiber CAI from my old M3, fits perfect, problem solved.

And finally a few pics with the powder coated wheels and finished exhaust. :D

Won't let me attach two pics from my iPad.

Re: Comfort comes home-Project Lexus GSX
 

Looks really nice and clean! Glad to see you're enjoying it!

Re: Comfort comes home-Project Lexus GSX
 

That 5th gear was one of the best mods to my my old car. I hope they go thru with making a 15-18% one that would be sweet.

Re: Comfort comes home-Project Lexus GSX
 

The 5th gear sounds great, I want one. I'm waiting for the right recipe on a "quiet" exhaust! One of us will figure it out someday, but I really like the look of yours from the rear.

Re: Comfort comes home-Project Lexus GSX
 

I wondered about that. I had a 944 where 5th gear was unusable til about 75 mph, this 11% seems about right. I suppose with the 2.4 and a regular turbo, you could get away with a taller 5th like the V8 cars.

Re: Comfort comes home-Project Lexus GSX
 

I'll get there. This downpipe was used when I got it and a little worn out. A fresh new one from RRE should fix it. Plus, I've got another SS bullet muffler to add if needed.
