well, 30" it was, Flowmaster 'tis not. I must have misunderstood, but it's just some brand that the guy at the exhaust shop gets from his supplier.
Either way this M-Fer is MASSIVE! It's right about 2x the diameter of the stock resonator, and built totally different inside.
I got everthing welded together tonight and took it out for a drive. Now I DEFFINITLY need different mufflers. I can barely her the thing! Not that it was loud before, the exhaust is all stock. At least it doesn't sound like a VTACK now!
I'll try and post a few pics tomarrow
