I have long tube headers and I am going to run 3" x-pipe or 3" prochamber but I want everyone’s opinion on which one to get.
I will be running 1 chamber 3" flowmasters and 3" turndowns. The motor will be a 347 stroker.
How do you think this will sound?
I was thinking the x-pipe would tone it down a little and I have heard the pro chamber does not sound good but I have never heard one.
