Hey guys , I just finished putting on some Flowmaster 40 series' on my monte, and let me say I now know what you were talking about. It really sounds great, it was the sound I was looking for.

Its actually kinda loud, being it's just headers real duals all the way back. It actually sounds like the recordings on the flowmaster site.

question thought, does you guys cars sound somewhat quieter at idle, but when you hammer it, it gets louder?????? What i mean is, is that a normal flowmaster trait?

eaither way its bad@ss. I recommend them.
