I have the hooker cat back installed on my camaro. It sounds really deep at idle, but when you rev it up it cackles just a little on deceleration. A buddy of mine said that if I went with turndowns instead of the hooker 3" dual tips that the kit comes with, that the cackle will be slightly less noticable and the exhaust will sound a little better in the upper RPMs. Is there any truth to this at all?

 

You might get less noise because your pointing it at the ground but it will still be there.

 

That blatt, crackle--or what ever you want to call it is due to the fact that it's a crossflow muffler. Nothing you can do about it, short of finding a way to get a thru-flow muff in there.

 

Well seeing as it isn't that bad with the hooker muffler. I guess I will just deal with it. The Hooker aerochamber has no where near the cackle that my flowmaster had
