differences between Rotary engineering vs Racing beat exhaust system
anyone's experience with the two? To me they are very identical,but ive read that RE system makes a bit more power.I my self have a RE header and just purchased the presilencer from a member and was wondering if it was going to be much louder then of a RB. give me some inputs.....

I have a RE exhaust system that I bought new back in 1990 or so. Its very well made and very quiet as folks that have heard it can tell you. Thats said, you can't get it new anymore and at 18+ years old most RE exhausts (especially the presilencers) will be deteriorated. So much so that they may rattle or make other noises.
I know I'm looking at replacing the 2 silencers and possibly the muffler now because the front silencer is coming apart inside and has a rattle at idle that drives me nuts.
Your best bet is a new RB street port dual system. Thats what I'm looking at getting to replace my current setup from the headers back. Buying used exhaust components is like getting used brake pads, they only get removed and sold when they are failing.

The RE and RB headers are a bit different. The presilencers will not bolt up. IIRC, the 6 bolt flange is reversed between the two and the angle is a bit different. You won't be able to bolt up RE stuff to RB stuff.
My very first exhaust system was one from RE. The front presilencer eventually failed with some internal metal bracket breaking loose and causing a racket. I wound up replacing the entire system with the RB dual pipe system.

I have a RE roadrace header and RB, and as stated the flange is reversed. The reason I like the RE better is because the runners turn after about an inch where as the RB turns right at the flange. So it "should" make more power. The isc is by far the best uncollected header out there. I do tend to be a RB hater but if youre just building a street car their quality cannot be matched, but neither can their prices!!! lol!!

i have a full RE system. I love it other than the fact it hangs SO freaking low. I have also had a RB header and presilencer coupled with a magnaflow and borla. That system sounded awsome. I loved the hybrid system more, but i would have changed a few things about the design(pipe diameter, 2" instead of 2.5", and borla street muffler instead of XR1, and possibly thicker wall piping).

my 12a has a 7" camden and I plan on doing a 2.5" after the presilencer. By doing this affect my cars performance ( increasing or will it hurt my performance) any thoughts ?

the most important thing about exhaust size is port size and where you want to make peak torque. look in the naturally aspirated section. there is enough info in that section to never see another exhaust question again. fyi my new exhaust will be 3" but i want to make peak power at 7500 rpm.

My friend Dave has an old RE exhaust system. The header runners do turn more gently than the RB headers but that system is the rustiest thing I have ever seen! I have never seen an exhaust rust out like that one has. Holes have rusted through in many places. There were so many fixes to it that we've now got patches galore and a few new pieces that were fabbed to fit. I've seen people claim Pacesetter headers rust out but having owned a set I can truly say that the RE exhaust systems is the worst I've ever seen in longevity when it comes to rust. The Pacesetter definitely outlived it. It looked like a nice system when it was new and the design seemed sound. The materials were crap though. Keep in mind this car isn't up north where there's salt on the roads in winter. This is Houston. Admittedly it's an old system but it didn't age very well.

Yeah the RE system does hang low. The front presilencer is always hitting speed bumps in parking lots and some curbs of driveways. I've got all the hangers installed that it can accomodate. It could be old engine mounts but I've never been motivated enough to deal with it.
No problem with it rusting out or any of that. Mine is almost 20 years old and has been on the car for 30 or 40K and the front presilencer is getting a rattle in it now at idle. I'll probably go with the RB street port setup next or a custom one. Haven't decided yet. I won't deal with that until the SP motor goes in later this year.

My experience with both systems are different. I used to have 2 FB's, one with RB header and the other with RE (both dual exhaust). No issues with height. I will say that both brands are built well as I still have them (over 15 years).
Now, with pacesetter, no experience on rotaries but I used them once in my 2TG and it was a bad experience. I had to switch with doug thorley (sold at TRD) as the weld on the engine flange started breaking in less than a year
