| You can get pipes repaired you know. I asked about how to fix a similar dent on the connecting pipe between the can and exhaust collector.
Apparently, you can weld little stubs of metal to the outside of the can, use them to pull the dent out then cut them of and grind them flat. I didn't bother getting my cans done because a set of DP pipes came my way.
Do a search on Mike Davis at Robsom Racing, he reckoned he could get this done so that you'd hardly know that there was a dent and not for silly money either. |
