are you really willing to pay out your ass for a ti exhaust when the weight savings over a conventional exhaust wont even be noticed? unless you're building a race car where you're trying to drop every ounce possible. :dunno:

i've never heard the exhaust you're talking about, but i have heard the mugen and hytech twin loops. about the quietest exhausts available without sacrificing any flow. of course these are rather expensive as well. my brother had a hytech on his gsr before it was stolen and under 4k rpm it sounded near stock.
