Need Opinions on exhaust

335why · 08-01-2011, 05:13 AM

I just got done installing my Raceland DP's (Pain in the ass) and i thought the car was going to be much louder.

It's basically a tiinnyyy bit louder with just a slightly different tone.

I want the car to have a little more sound to it but dont want anything crazy.

So, options

1. Remove secondary cats
2. Remove resonator
3. Take off Both

Also, will the car drone without the resonator??

Don't remove the resonators or you'll get the dreaded "drone" effect...not very pleasant if you have to drive any significant distance.

Isn't it true that the coupes don't come with resonators??

Would taking the secondary cats off make any noticable difference in sound?

Yes and yes..RL pipes are skinny..they dont sound as good as true 3in DPs
