Exhaust + cams = ???

:) Since there's been so much talk about exhausts and headers and cat pipes and such and their overall effect on the volume/tone of the exhaust. I was just wondering what kind of effect more/less aggressive cams would have on the exhaust tone/volume. I already understand that a more aggressive cam will give a lopier idle, but what about under acceleration? Deceleration? Cruising?

not sure about the actual cams themselves, but i know messing around with cam GEARS doesn't really do anything.

cams might make for a more interesting and unique exhaust note, but i doubt it could affect the volume.

Cam gears do something only if they are there to actually and are used for advancing or retarding the timing. I don't know if it would really creat a different exhaust sound. If you want that, get a race header.

Cams made a big difference in my car after I installed them. Ive got a borla setup, and after I put my cat 1's in, in the upper RPM's where the car would get a little high pitched, its turned it to more of a roar, got alot of compliments from some people who only drive V8's and who used to give me alot of crap about the sound of 4 cylinders. Now ive got a race header and its all gone to crap, but the good ole days.....

Well I figured having the valves opened longer, and at different times would change the actual sound of the exhaust.

Your correct on this.

Cams effect the amount of lift and the amount of time the valves are going to open, therefore controlling the amount of air in and out. They do have an effect on the sound.

yea i would think they would have alot of a difference in sound...look at a honda when it switches over to vtec how much louder the motor gets....so if u switch ur car to a more agressive cam it should have a different sound
