horrible resonance at 1700-2000rpm
after I had new exhaust put in today. Had a dynomax bullet axleback exhaust/muffler placed. Great sound though a bit loud. But teeth rattling resonance. Anyone have experience with this problem? Will be bringing it back in for removal/replacement later this week. BTW drove it without mufflers and sounded great, just too loud for my taste.

Re: horrible resonance at 1700-2000rpm
Yes, i had some resonance with the stock mufflers. It was not as severe as you describe with your exhaust, but it was annoying. All gone with the Corsa axleback.

Got back to the shop yesterday and we decided to add a muffler after the secondary cats and keep the bullet mufflers at the tips since I like the sound quality. Drone is down 80-90% at 2000rpm and virtually gone at 2700rpm. Sound down about 40% overall but livable for the wife now. Will add some dynamat to the trunk to see if I can remove the last of the resonance. Underbody parts already has rubber spray.
