weird Spugen sound at 5000 rpm, for some reason recently, my spugen gives this weird sound whenever i go up to around 5000 rpm. Its like a sharp rattling sound. once i pass the 5000 rpm, it sounds more normal again, dont notice the sound as much. it seems at each gear at 5000 rpm, sometimes the sound appear. please advise.... thanks

I THINK I GET THE SAME RATTLING NOISE AROUND 5700-6000 RPM. I THOUGHT IT WAS HITTING THE UNDERCARRIAGE BUT IT'S NOT. I HAVE NO IDEA WHAT IT IS.

resonation due to the exhaust combo's natural frequency?

Loose heat shield?

Get it up on a rack and start tapping the undercarriage. Your sure to find it.

Just went through this issue.... replaced my damn cracked ass heat shield and still have the rattling... Its the resonator....!!!!


Cut it out and make a straight pipe

check for an exhaust leak

My experience as well. My rattle was coming from the exhaust tips banging against the cut-outs because the crappy 'aluminzed' piping had warped and the mufflers had moved inward. I now have an Espelir system that fixed that problem. The only problem I have with the Espelir is the horrible appearance of the fart can mufflers and splayed outlet design. I wish I could have seen an actual S2000 installation of this system before purchase. It's SO nigga!

Geez, I thought I answered the question. Spugen's choice of aluminized piping is crap, plus the lack of a resonator doesn't help. Spugen is overpriced junk!!
