i just installed my dynomax super flow muffler at my local shop. it sounds great to me but not loud enough yet. i plan on takeing my resonator out monday. i cant wait. right now, the exhaust can be heard up to 2500 rpms then fades away but my intake takes over. i hope replacing the resonator with a straight through pipe will free some things up.

 

My exhaust made a tinny, rattle noise whenever I got on it. Sounded very ricey. The guy at the ehaust shop told me that the noise was due to the fact I had a long stretch of piping and the sound was bouncing around in there. I have 2.5" custom catback. I had them put the resonator on after about a week and it was still just as loud but it took out that bad sound. Now it's got a clean throaty sound. Do you have a y-pipe? That'll help make it louder. Also, is that muffler a straight-thru design? Mine is and it's pretty loud. Sets off car alarms that are set too sensitive.

 

the muffler is straight through and thats all i have other than the intake. i plan on just replacing the resonator with a straight pipe to go along with the stock piping. will this be significantly louder like yours, or only if i get the 2.5' piping?

 

What size piping do you have now? If you have smaller piping you may be able to get rid of the resonator without having that tinny, rattling sound. The muffler shop guy told me the larger the pipe, the more room the sound has to bounce around. There wasn't a noticeable difference at WOT when I had and didn't have the resonator. It basically killed the horrible drone around 2000-2500 RPM's. Before I had the resonator, it was almost impossible to talk to anyone in the car while driving around town. Since you don't have the y-pipe, it probably won't be this bad.
