I have the Carson Tune exhaust from the cat back on a 99' GS3. I like the sound, but I was thinking of getting the B-Pipe from Carson Tune as well. I'm concerned with the car being too loud. Does anyone have this combination? If so, how does it sound?

I'm also thinking about getting the SRT Intake, how should it perform with the Carson Tune (w/B-Pipe) combination? I also read/heard that the SRT Intake was very loud. Does anyone have a partially open sound proof/heat sheild or where I can get one from? Thanks for the help.

talk to lxogood, he has the carson tuned together with the b pipe

I have both Carson tuned pipes and you gain a few HP through the mid-range with the B pipe. The sound it provides is only a little bit deeper than if you didn't have it on. However, with the two pipes bolted up, it sure does look sweet...

Here's a pic of the B pipe..

Do you think the SRT Intake will improve performance a great deal with current setup (no B-Pipe)? Do you know any place i can get the sound box/heat sheild? Or do you think that I'll get more HP from the B-Pipe setup?

Also, I know there is LSD / Supra 3.76 for the GS4, but is it availible for the GS3 as well? Oh, and I'm planning on getting the Dragon TC too. Thanks for the info.

I believe the GS3 already comes with some low (numerically) higher rear-end gears. Also, the torque converter is pretty loose on the GS3. Lexus made them like this to give the 2jzge a little more acceleration. The GS4, on the other hand, comes with a tighter torque converter and a higher (numerically lower) gears in the rear-end because the V8 makes a lot of power down low already. That's why people with a GS4 switch the TC and LSD. Pretty much, it's not going to help much on the GS3.

Here's some info in another thread regarding gearing and the stall speed:

So pretty much, you won't gain much from a gear swap because your stock gear is 3.9 while the Supra LSD is 3.75. You might get better traction when exiting from a corner with the LSD though, but I'm not too knowledgeable about that.
Changing your TC will adjust your stall speed a little higher, but you might not gain much performance for the money.

Hope this helps. All this info came from this thread: https://www.clublexus.com/forums/sho...hreadid=138815

lxo...any update/word on the gs3 headers from carson?

LXOGOOD

Zero...Nada... Sorry guys

that's correct. the lsd basically won't work on the gs3, or i should say won't help. the gs3 already has a higher gear ratio, putting the supra unit it's only going to be slower. lsd gives you the traction, but off the line you lose big time already

for the tc, there is one for the gs3, however the gain isn't as noticeable as that for the gs4 coz' it already has quite high stall speed for more power. on the gs4 the tc gives a lot of power gain.

that's why you see more people with gs4 doing the tc and lsd mod

Yup, NA motor should have shorter gearing & FI motor should have longer gearing
So i guess if you boost the GS300, you might want to get the supra LSD for the longer gearing correct? And keep it stock if you're all motor.

it could be true, but it also depends on how much boost you running and stuff too, it's all about tuning. some say 3.9 is tall for FI, but some says it's perfect. it all depends on tuning i guess

I am sorry, Rom. No offense but did you just basically repeat everything LB Lex just said?

and, so? at least i think i provided a bit more information as well. what's your point

jtanoyo1

So, nothing, bro. Just pulling your leg and trying to up my post count.
