Different styles of down pipes
I noticed that perrin down pipe has two seperate tubing that ends into one. i guess this seperates the waste gas from the exhaust gas but ends up still going out the same pipe. Is this a better design for hp/tq? or is the down pipes from other companies that feature just one 3in opening better. Need help please educate me.
