I am getting that exhaust friday, what does the sound compare to?

Jefsmr2

Almost sounds like a Mustang in my opinion. Its really deep and throaty. Sounds great from the outside, but the cabin db is too loud for my taste. Lot's of resonation inside the cabin.

Dont worry Chris, it wont be as loud as my HKS Ti exhaust or even Tomek's custom exhaust.......

hey guys, not sure if this will help you or not but when i first called GReddy about there exhaust they said that the system was designed for the GS 400. they also said that the system is louad on GS 300. Again not sure if that helps, just wanted to guve my $00.02

P.S.

hi guys, did any one try the RMM exhaust? How des that sound...? i want to buy one to improve power, but affraid of the noise like Jefsmr2. Please give me some opions...thanx!

RMM is almost on the same level as Borla. Mean Gene had dyno saying that Borla itself will add 7 horsepower if I remember it correctly while RMM is about 3 to 5.

Another note to keep in mind. The RMM exhuast is only rear mufflers NOT a cat-back. The sound is ok. If you have an 8cyl. you should go for the Greddy unit. It sounds so mean in a good way.

I've had the Carbon Borla's on my car and then bought the RMM Signature series. While the RMM's look good, their almost as quiet at the stock system. The Borla's also looked good, but the resonation @ 2000 rpm's was a little loud. How much louder are the Greddy's compared to the Borla Carbons ? Anything compared to say a 5.0 with no cats and 2 chamber flowmasters ?
