Nice looking exhaust Buly!
Here's my new exhaust - I've decided to go with a 3/8" wood flange and 2"
ABS pipe - less prone to cracks and readily available in all small towns
across the USA just incase I go down again. If I have the insides ceramic
coated it might even last more than a couple nano-seconds. ;-)
