: Decibels Difference - Aftermarket Exhaust??

Hey Guys,

Just wondering what the difference in decibels was from stock exhaust to various aftermarkets at idle?? I want to get a Stainless Works, Corsa, or Magnaflow BUT worried it'll be a major sound change from stock. I take clients around in my car and having a "wolf in sheep's clothing" is perfect. Loud aftermarket exhausts aren't conducive to the people I entertain.

Thanks!!

Funny you should ask.
I just received my Corsa Axle Back "Touring" system today, and I was planning on measuring this myself.
I'll measure the levels tomorrow, of stock setup, and in a few days when I get it installed I'll measure it agin and let you know.
Probably be Sunday or Monday, as I'll take care of the install, most likely, on Saturday.
We shall see.

I installed a Corsa axle back touring exhaust because it was supposed to eliminate any drone - I can actually say that in the cabin I did not notice the difference but behind the car is an amazing difference - your clients should barely notice the difference. I love the exhaust.

My thoughts exactly!

Unless you do headers and catback, it will be quiet enough inside and louder out. It's not Corsa specific...

All these responses are exactly what I was hoping to hear! Thanks everyone!

I've already contacted my local shop to order the Corsa....best rates they saw were around $1450. Anybody know of a better deal than that?

Thanks again!!

The price for the Corsa Touring was in the 1,200 to 1,300 range -- but i bought it from the speed shop who did the install -- the install cost me $80 -- but I tipped the installer an additional $40.

Yep. I think I originally was looking at the Sport exhaust which I more expensive. Touring is online for ~$1,200.

What kind of power gains are you guys seeing with the Corsa??? I'm going to have a smaller pulley installed and tune at the same time. Hopefully seeing 20-30 HP gain over the 480 at the wheels I've got now from Intake and tune.

Cheers!

Honestly I did not measure it -- I did not do a tune as I did not want to risk warranty -- but I did also install an AIRAID Cold filter intake -- I did this about 1 month after the Corsa Axle back touring -- noticed a big difference once that was installed -- but again have not measured it nor did I do a Tune -- so it may all just be in my head!!
