I am just finishing up my 67 Coronet RT convertible. It runs but not well yet. It is a stroked 493 cu in with 1100 Holley, Eddie heads and intake with TTI headers. I have tried a few mufflers but it is still too loud and there doesn't seem to be room for resonators. Any suggestions?
Are you running a cross over?
Yes... there is a cross over
You didn't mention what size pipe you have but the bigger it is the harder it will be to make quiet. Header make it even harder to quiet it down. Did you try walker quiet flow? The 2.5" in/out part # is 21548 summit sells them.
Thank you I'll give Walker Quiet flow a try a try
Ear plugs...........
I run straight 3" exhaust with cutouts,they stay open all the time,the louder the better,who needs to talk in the car anyway????
