So I am pulling my engine this weekend and one thing I am looking at changing is my exhaust, I am interested to find out what the Pro's and Con's are of changing and what is the process/ parts will I need......
Currently running a BBC 502

Thanks

The only downside is the noise otherwise dry is the way to go!

I wish there was a way to tell juat how much the difference is, short of doing some research in a back to back fashion.

I run full dry CMI's with GGB mufflers. It is pretty loud, but the GGB's take the bark out of it. Without them, it was unbearable . I wouldn't recommend dry tails. There really is no need for running them, unless you are running a cam that would create excessive reversion.
