RB Exhaust Q
Say I get a RB header and muffler, but skip the presilencer, or better yet go for the long-primarie set-up. (theres no emissions where i live) Will my car be unbearably loud without the presilencer? Will i suffer from any lack of back pressure problems?

I have RB header to muffler, with only straight pipe in between. It's not loud, I actually like the way it sounds. I have a brand new presilencer, but have never put it on. I've had no problems with back pressure.

The RB muffler does a great job at quieting the rotary but it certainly does add exhaust restriction plus the pipes leading up to it are small. I replaced that muffler with bigger dual 2" pipes leading up to it and a Magnaflow 2.5" straight thru 18" can muffler and that motor really started to rip. Loved to rev. LOURer but still bearable but I had the RB road race header and dual presilencers.

presilencers don't restrict exhaust flow. They're the same diameter inside as the header pipes, but the exteriors (from what I can understand) are wrapped tightly with a material somewhat remeniscant of steel wool.
Yeah they're more expensive, but you don't suffer any performance cut. And the cops won't notice you as much
