exhaust help?!

I have a 87 883 with 1200 kit, cams, and 2 in drag pipes. A guy told me last night that I would gain power going to a 1 7/8 drag pipe or a set of pipes with baffles in it

. is this true? It is plenty fast enough as is but I was wondering if this was a true statement.

You will get more power with baffles for sure. I don't know about the 1 7/8" pipe. A good 2 into 1 with baffles will provide even more power.

He was right about the 17/8" pipes and baffles. But, drag pipes suck unless you ride WOT all the time, a good 2-1 is the way to go.

Yep, it will have more bottom end power with baffles in the 2 inchers or 1 3/4 pipes with at least a little restriction, like a lollipop baffle or even a bolt thru the end.

+1 2 into 1 pipes give the best performance when its tuned right.

that was great information. guess I am on the prowl for new more restrictive pipes. too bad I can't afford some of those RB pipes. they look like they are awesome.
thanks guys
