So I went to the track about three weeks ago, and ran for the first time. I went 13.5 @ 109. While going down the track when I shifted into third gear around 4500 rpm it felt like it bogged down, or almost stalled. Since time I have changed plugs, checked wires and applied heat socks, as well as put on a new coil and opti. The reason I am a bit worried is I have true duals, and on the drivers side the exhaust sounds bad ***. On the passenger side it sounds quieter and I don't feel the heat from the exhaust like I do from the drivers side. I don't have a a cross anywhere in the exhaust, so I know that something has to be wrong with the passenger side. I need some advice, and what the issue could be. Any feedback would be greatly appreciated!

 

Is there a way to remove the exhaust and check for blockage, and are you sure the wires are in the correct order? Have you done a compression check on the side with issues? There's several things to check for is the car running rough, hard to start, etc or is it just the sound and lack of equal air flow that have you worried?
