Re: 2bros exhaust whats better flange on or bolt on ?
I would say that the one that replaces the s s bend pipe would net you more hp and thats just becasue I'm assuming the 2bros peice is better than the OEM. I dont have any # to back that up i'm just following the logic of a full system gets the most hp so the closer you get to a full system the more performance gains you will see. I also have heard that of full systems need a PC3
but flange ons dont really need one. I'm not sure how the system with the S bend would fit in their.
