The Blitz Nur Spec is frickin awesome. Outlet pipes look like space shuttle exhaust, too much for those that like the classy look. But God it sounds good. Slight performance increase, highway, but slight perfomance decrease from standing start due to lower restriction. Car runs smoother in general.

 

I have the L-Tuned. Don't have any pics yet. I have not had any issues with droning, which I always thought meant a reverberation in the cabin. However, there is a very slight buzzing sound. I applied a gallon on liquid sound deadener to the tire well and the areas between it and the seat back. This helped a lot, but did not cure it so I ordered some Second Skin for the rear seat back and bottom which I have not applied yet.

I always thought less restrictive exhaust cause loss in low end power in smaller displacement engines, but had never heard of this in larger displacement motors until I read a post above where someone had experienced this with their GS4. I think my car is more responsive feeling with this system. Also, that it is louder than stock b/c it telegraphs my presence so people will get out of the way when I am on the gas versus being surprised by me coming out of nowhere.

 

wait theres a borla exhaust for the is350...? where is it!!! lol

 

I'm surprised more people don't have the RMM exhaust. It's a great sounding exhaust. I don't know if there was a break-in period but the exhaust seemed to get louder, now it sounds even better but it's still not obtrusive enough to be annoying. The only problem is that I can't hear the exhaust note that well since I'm the one driving.

 

Lexizm, do you have a sound clip of the Carson Tuned?

 

No I don't, but I'll take one just for you sir and since I don't have one to begin with. I'll do it tomorrow.

 

i have the borla exhaust and it had no sound to it, but i ended up removing the resinators and it now sound good and deep. not too loud.

 

i love my Tanabe Hyper Medallion w/ removed resonators

 

magnaflows with no resonators

i like it, it has a nice tickle to it
reminds me close to the 350z/g35 sounds
no ricey, yet exhaust isn't there
you can tell somethings different though
and at WOT, theres definately a growl

 

Had the HKS Hi-Power. But it was just an axle back. Then got the Carson Tuned full catback as a gift from the wifie. I have since added the S&S headers and a custom Magna Flow X pipe. Got rid of the resonators from the Carson Tuned. So if anyone has any use for this let me know. Its still so beautifull and intact with the flanges. Now only employing the Carson mufflers.
This set up sounds just awsome. Not as loud with the headers and all, suprisingly. Most of the power gained is in the mid to high RPMs. Exotic rumble sounds so mean.

 

ooo la la....just got my l-tuned exhaust on a couple days ago...woohoo i like the sound especially at full throttle acceleration...well there goes my gas mileage....damn da bad luck!!!

 

I have the Borla axle-back. It's a bit too quiet and not as deep, but its much better than stock. I wanted to retain that classy look. The other exhausts looks too much like coffee cans for me to consider. It just doesn't look good for my car

 

l-tuned here, probably the quietest aftermarket exhaust i've ever had, but like gsteg i don't care for coffee cans.

 

I got the Medallion Touring. Noticable power increase on the top end. Really good look and sound. Would reccomend

 

Does Borla make a catback exhaust for the 2Gen GS300?
