Firstly does anyone have the flowmaster American Thunder Catback? Whats does it sound like? I currently have a dynomax but I am starting to find the sound a little annoying. Secondly I have a noise coming from under my hood which disappears when the clutch is push in, let the clutch up again and noise returns. Any ideas?
thanks in advance

 

I have the dynomax race bullet. It sounds great at idle and 1st 2nd 3rd, just when you get up in the gears especially 5th gear just sounds like a booming mess. I'm after something with the same deep sound, same loudness but a better sound up in the higher gears.

 

Actually I meant to say I have the dynomouth set up.
