which exhaust?
 

ok need some info on some exhausts, ive been looking into getting a new system for my 83 12a, only has 70k miles on it on the stock engine. I wanna help it breath so any tips or suggestions for a new exhaust system or quick tips would be great!

Full Racing Beat, either the Power Pulse system or the Street Port system. Both are fantastic systems that give great power increase, great durability, and an overall excellent tone that isn't too loud for the street. There's plenty of optons if you want to go custom as well

I'm a fan of a Power Pulse presilencer with a Borla main muffler. A friend has this on his rotary 510 and it sounds really nice, and not overly loud (but louder than the RB setup) and flows really well. If you want it quieter, add a Magnaflow 4" round and you end up with MosesX605's setup. He has a sound clip of it on here somewhere, very quiet and mellow.

If you want something bolt-on, there's no beating Racing Beat's long-primary "streetport" system.

+1 for the RB streetport. Nice n quiet idle. At DGRR during our midnight run I had my hood popped while I was fiddling with the carb and the people standing around were all saying how quiet the car is. The RB also wails at full throttle. Nice deep sound. dj55b has a custom exhaust that uses Borla (I think) mufflers and I gotta say, it sounds rather tinny and it's very loud at idle.

+1 for RB Street port exhaust w/Power Pulse muffler. its even semi quiet at wot.
the people I autocross with were surprised I maid the car that quiet.

+1 for the RB Street port system, great performance and sound!
