Thought about using those inserts, haven't done it yet. My collectors are slip on and don't have flanges. Currently running them open. I like the sweet music they make.I need some ideas on how to add mufflers to my fenderwell headers on my 56 150. Can anybody post some pics? Also, has anyone tried the 3-disk Car Chemistry header inserts in their fenderwell headers with a turnout tip?
As long as you're not being "stoopid" I think the police will leave you alone if you run open headers. I have cutouts on mine had them open and was sitting at a stop light, it is loud, louder when accelerating, and the cam gives it a definite rumble/lope, when a patrol car pulled alongside me the cop just gave me a grin and thumbs up. We were side by side when we left the light...Probably a little too loud and sweet. I had heard of a story about a guy with a 55 that had the CC inserts with turnouts. A police officer had pulled up alongside him and noticed that he had these open looking headers, but did'nt write him a ticket because it was'nt too loud. don't know if this is true or not.
My friend Rob tried them on his T bucket...same thing not much difference...he pulled them off and just runs open headers nowI once tried a set of the 3 disc Car Chemistry diffusers on a stout big block Corvette with side dumps and unless you took a reading with a decibel meter,
I couldn't detect a difference using them.
Those suckers did not make a bit of difference as far as I could tell, neighbors still summoned the cops everytime I pulled the car out of the garage to do something to it.
I wound up taking them off since they didn't make it any quieter, your results however may vary.
