I already got a Two Bros Exhaust that I love, is there anyplace that sells just some aftermarket headers to get the performance gain?
That's why you buy a slip-on that's an actual muffler and get a PCIII!! I've got a Termi GP on mine and it's perfect. Not too loud, doesn't shoot flames or backfire. What do you think a full system exhaust is?? It's a header connected to a muffler. The header is freeflowing and the only baffling is in the slip-on. Same principle, different price tag :werdi was reading that the mjs is hollow all the way. that is not good on an engine. it will be extremely loud also. the factory slip on will not create enough backpressure for it so i know the 2 bros will not. an engine needs backpressure to a certain degree to run at full strength and get life out of it. the other mid pipes are ok to a certain degree. a full system is the way to go. i know they are expensive but it will be cheaper than buying an exhaust and an engine.
