Well for years I listened to the sound of a stock cam, with a stock H pipe, and NO mufflers. I think it sounded pretty darn good. Now I have this mild lopey E-cam, a 2 1/2in O/R pipe, and I started out with that good ole original open pipe I hooked back up. Sounded pretty darned good again at idle. The problem was it cackled like a hen in heat. I mean serious cackle at the rear. I do not know if it was the 3"W X 12" long chrome tips I had or what. I decided I had to go with a set of mufflers. I chose the 40 series Flowmasters a couple weeks ago. I had them put on for a mere $40.00 and I thought that was good considering I brought him the mufflers and he only had a few feet of pipe and welding involved. I did not hook back up the rear section. The turndowns are at the rear axle. This car sounds pretty decent during acceleration. I just can not stand the DRONE. I feel like I am in a sub woofer box. The plastic vibrates all in the interior and I feel like screaming it gets on my damn nerves so much. I wonder how all of you guys deal with this. Do all of your favorite mufflers do this? Spins, Macs, Magnas? I had a 400 BB with 2 cherry bomb glasspacks, 4" X 12" in HUGE tips and I thought it sounded awesome compared to this. How about the Dynomax bullets? I dont care a lot about having loud exhaust. Just no cackles and no sub woofer interiors. Anyone wanna set of 40 series ORG Flows? Even has the 2 1/2 pipe weled on the inlets.
