Quick sound clip before I redo my exhaust, put a new cam in a couple weeks ago and now have to finish off the project with a 4" exhaust. I did new headers and mid pipes early in the year.

Noticed after the larger cam my exhaust sounded odd, so did some back pressure testing. I knew my current exhaust was a big restriction but damn. Luckily I was already planning to do a 4". Current is only single 3"

I seen 10-14psi back pressure......


Anyway here is a short clip

Typically when you go up in pipe size the tone gets deeper and less defined. Not by alot but it does. I am curious of what it is gonna sound like afterwards.

So what type of cam did you install? It sounds really good

I agree with this. But his exhaust is also very quiet. I think it'll chop more with the 4" exhaust almost simply because it will breathe better and let more sound out.
