I just put the mac 2 to1 system on my 80' 400 and just straight piped it sounds exactly how I want it; loud enough to piss the neighbors off down the street! But anyways with the pipes and a short angled tip it runs good w/ no backfire and what not but I did notice the significant change in power without the muffler that came with.
So I guess what I'm asking is what is the best way to improve performance while keeping it straight? Is there any packing or back pressure ideas and lastly what negative effects will this have on my engine? I will be posting pictures and video of sound, just for fun.
Anything can help!
