cool, i found this on fleabay:
http://cgi.ebay.com/ebaymotors/BMW-3-Series-Heat-Wrap-Exhaust-CAI-Cold-/26042...10 meters (about 30 ft), 5 cm wide, would be perfect, and its only $20, compared to almost $50 for 50' at advance auto. the seller has a ton of these labeled for different cars, but they're all the same - i just chose bmw 3 series because i have an e30
.
I've been putting off heat wrapping the exhaust because i like the shiny header but its getting a little rusty and i scuffed it up trying to clean melted shoelace off
. i'll rust treat it and heat paint it first, of course.
