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)

To.... 01'325rip
Yes i used a MIG welder,it was not easy,because the exhaust is double
walled,next i oversprayd the weldings with zinc spray , to prevent rust.
Exhaust was opened on top...so you can see ....0,0 .
It's now six months ago,and looks still perfect....and importand...sounds
realy amazing...just like i wanted,the ///M3 should sound like this
from the factory,and importand for me...0...drone !
i was started the mod. 09.00 am and finish...18.15 pm.
I am verry....verry happy with this mod. ,this is the best thing i ever done
with a car !
You can asked me what you want to...i will anser all your questions about
this oem. exhaust mod.

Good question from you.....
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....

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!

No...no watch the video again....!
Before mod. full trottle = 90 db
Afther mod. full trottle = 93 db (this also depends....warm or cold start,cold start is much louder ! )
99 db...was the Eisenmann exhaust that i have heard in person,
droned like a mofo !!! i have heard in person...Eisenmann,MPerformance,Akrapovic
Oem exhaust mod. 0,0 drone, with the Helmholtz chambers designed
in the oem exhaust....Helmholtz = anti- drone
