Default Re: my new build shopping list!

My only tip is that if you are going to lengthen your exhaust system with mix and match parts, research expansion chamber tuning information. There is a special relationship between the length of the exhaust pipe and expansion chamber. Also the angle of the expansion and the angle that closes at the outlet have a lot to do with the way sound waves help cycle the motor as efficiently as possible...
