i am looking for cat-back exhaust system for my 00 GS300. i been searching all over CL forum to find the right type of exhaust that meet my needs but none come in mind yet. My goals is to looking for nice appearance and QUITE exhaust and don't want to loose any low end power. Which of the following do you think will have QUITE sound. Couple decibles louder than stock is fine but not too loud. Please range them from 1-10 ( 1stock sound.......10 loudest). Thanks for your time

1. Apexi WS
2. HKS
3. Borla
4. lsport line
5. ?

 

i think you should try ltuned or carson tuned or borla, those are on the quiet side

greddy is super loud, hks is loud too. i have apexi, if you want absolute quietness, don't touch it

 

Does Ltuned, lsportline and carson tuned came cat-back?

rominl,

How do you range the loudest of your Apexi?

 

10 being loudest, i have sat in greddy before and it's an easy 9, coz' it's loud all the time. my apexi, i say it's 6, it's loud when you are between 2k to 3k. there is no resonator so it's loud. after 3k the car becomes very quiet again

 

I have L-tuned on my car and is BARELY louder then stock...

 

You could just do tips? It would save you alot of money

 

Agreed, the Greddy, even tho mine isn't installed yet, i have heard....VERY Loud, HKS is quite loud too. Don't know about the Apexi, but for guranteed quietness, Leave it stock.

And as LSportGS4 said, you could just add tips. I did and it maintained it's quietness, and just added a little of that V8 growl when you punch it.

rominl,

Does your Apexi came with resonator or you cut it off? of course, it will be loud with out resonator and a bit quiter if constuct with resonator. Thanks Rominl

Lsportline gs400
please post pics of your exhaust. thanks

 

Well I have L-tuned too and don't agree at all. It's MUCH louder than stock when accelerating. At cruise speed though, you're right, not much difference.

 

Maybe im just use to it... I havnt heard it out of the car... i need to have someone drive my car so i can hear it.

 

Precisely.

Especially at 2000 rpm it sounds mean! Other than that, it sounds too subtle for my tastes.

 

even worse, the apexi does NOT have resonator to begin with. after cat, it's just a straight pipe all the way to the muffler

BUT, it's still quieter than greddy, significantly. it's safe to say that the apexi is very quiet for a no resonator cat back

 

The TC upgrade's going to help with this too!!

 

My Carson Tuned Cat Back exhaust is quiet, almost as quiet as the stock exhaust but a deeper sound. You can't go wrong with the Carson Tuned if quiet is a requirement. The Carson Tuned also is flawlessly finished stainless steel throughout. I would also consider the Blitz Nur Spec exhaust, but I'm not sure if it's a Cat Back - it sure looks good though! Can't comment about the others as I have not heard them.

 

Thank you all for the comments.

Teelex,

Do you have the pic of the Carson tuned Exhaust on the car? Please post. Did you get your Vertex kit yet? i need one favor from you. Please let me know. Thanks
