[QUOTE="orange04, post: 11138782, member: 14862"] I have a 08 GT500 with JBA Long Tube Headers and Off road X-pipe and pulley and intake. Im getting this rattling noise coming from under the drivers side of the car under moderate acceleration only. Noise can not be heard free revving. Also the noise is worse when its cold. Noise starts at 2500 rpm and quits after 3000 rpm. Been up and down the exhaust, no contact anywhere and cannot see or hear any visible leaks. I originally thought the tubes were rattling against one another so I put spacers in the tubes, no change. I'm about ready to take the long tubes off and install the manifolds and an offroad x pipe. So a couple questions..... 1. Have you guys ever run into this?? 2. If I remove the headers and put an offroad X the car how much power do you think I'll be loosing in the long run??? Future plans are to run either a 2.9 Whipple or a VMP TVS. 3. Do you think it could just be the way JBA Headers are? I know alot of guys are running Dynatech and ARH, should I switch brands? Thanks for any help in advance, its driving me nuts!! [/QUOTE]
