Hi all, thought i'd just mention how happy i am with my new stock exhaust! $150 plus a lot of swearing removing the old one, and my kombi is sooooooo much quieter! I was used to loud kombis with my old bus that i had 6 or so years ago having extractors, and probably in average condition. So i didnt think my 72 was all that loud up until the last couple of months as it got worse. But the difference is AMAZING! So happy!
