hey nismor34 and eriktufa, My R34 has a 3 inch system from the turbo right back, it looks like a bolt on system too and runs AWSOME. i used to have a 32 and the exhaust would scrape over bumps but the 34 sits right up and doesnt scrape or anything. I know its a jap brand, brb, ok it says on it SR Jasma on it. "Made in japan" and has some number on it, i think there may have been only a few made. Also after having a closer look i think its a 4" system. Anyway guys i hope this helps. search the net for jasma or sr i supposse. and let me know if you need to know anything else.
