Be careful when you want to do this,after 2 minutes with my hands in the exhaust,
it was first blood (not the Rambo movie) LOL But a cut in my hand.....the burr of the stainless steel....cut like a scalpel ! Wearing leather gloves !!! But it's worth......now i have a super nice sporty exhaust sound !(believe me guys) |

Yes I used a MIG welder,it was not easy,because the exhaust is double walled,next I oversprayed the weldings with zinc spray , to prevent rust. Exhaust was opened on top...so you can see ....0 of the welds . It's now six months ago,and looks still perfect....and importand...sounds really amazing...just like I wanted,the ///M3 should sound like this from the factory,and importand for me...0...drone ! I started with the work of the mod. 09.00 AM and was done around...18.15 PM It was work , but really worth !

Make the full pipe good fit in between, and weld as fare as possible under the pipe. Don't worry...the perforated pipe was full of holes...so...no problem. Even the original (oem-pipe )are not welded 100 % under the pipe.....You should... heare the result....  Last edited by ///M Power-Belgium; 12-13-2012 at 10:16 AM.. |

The shop that did mine could not reach "under" the pipe to make a full weld either, but it was solidly in place before closing up and I have had no issues since the project was completed. I love the sound as well!
