Anyone ever use RB's Exhaust tubing?

Anyone ever use these to build an exhaust system? I have had two of their 2.5"
tubes and used it as breaker bars :). Now I want to actually use them in my
exhaust system. My current exhaust bangs on my axle on bumps, gets annoying
quite fast. What I will be using is from the RB header, to two Borla's, then over the
axle to the last Borla. Granted, I will only need a little of the straight tubing, how
much of the U bend pipe will I need? I am leaning towards 2 of them?

I haven't used just their piping, but I have the entire system. Tubing seems to be very heavy gauge, so it should help to avoid the "tinny" sound that thin tubing seems to produce.

3 Borlas?!? Holy shit man! Just wondering why you want the extra Borlas, rather than using their presilencers. I'm sure you have a reason, just want to know what it might be.

I've been thinking about getting rid of my RB muffler and switching over to a Borla this year. I'd like to increase the sound level a tad, and if it flows better then that would be nice too. But my RB system is just too quiet for my tastes. :)

Their presilencers (from what I hear) don't really silence that much. 3 Borla's because I can use them til they rot, then get them replaced for free :) I have a borla and generic fleabay muffler on the rear and it is much too loud. I loved it when I first got it, but now I wouldn't mind talking to my passengers.

I read that and Dan's make your muffler thread too. I would love to do what rotarygod talks about but the RB header's collector is a bottleneck in itself.

if i have time i'll snap a pic, the RB pipe is BEEFYx3

i'd think you would want 2 bends.

Be careful when you order the u-bends. Seems their site has a slight glitch on the 2.5" u-bend page when you click the add to cart button (see the ^25^^"> there?).

If you save this html code to your computer and click the link, it works. I simply edited it slightly. No viruses or trojans. lol :)
