Wow, Ospho is no joke and it turned out great. 

Stoked on the aluminum trim too.

Thanks Brian! There's quite a few things on the car that were inspired by your build, so I'm thankful for that. Especially ECUWorx, I've used the hell out of that program.

Same, I was super impressed! It also claims to add protection to the metal to help keep rust from forming in the future, so hopefully it stays this clean.

Dang you removed all the seasoning

Had to toss the car up on stands again to bleed the brakes since I messed with brake lines again. While it was up I decided to toss the new X pipe on. Overall was super easy to install, just tedious with all the metal braces that have to come off.
 

Only hiccup was the pipe didn’t come with hardware to transfer over the factory pipe’s heat shield. If I’m going to do it might as well do it right so I went out and found some nice grade 8 yellow zinc hardware to attach it. One bolt had to go backwards because of the clearance, which bugs me, but oh well.

I hope that you never forget that bolt is backwards.

The concours judges certainly won’t

Snow finally melted and we've had a few good rains in to wash all the salt away. Took the M3 out today and gave it a test drive after all the changes. Ran like a can of beans. Turns out I had crossed the two pre-cat O2 sensors when doing the header install. Finally got them swapped and it's no longer a can of beans. Tossing in a lil sound clip of the new X pipe too, sounds freakin awesome in person.

Throaty!

Thanks Pat! The tone is absolutely perfect, exactly what I was going for. The volume on the other hand is ridiculous, I'm sure you could hear it from a mile away. With that the drone is also a bit vicious at 2-2.5k RPM. Might need to go with a different muffler, but going to just enjoy it for a bit!

@Rekpointsnapped a couple exhaust clips this past weekend. Sounds pretty dang good for an S54!

Took the car out for the first decent drive of the season! Cruised along the Saint Croix river for about 200 miles to a neat stone barn pizza place down in Pepin. So happy with how the car has transformed over winter!

Thank you!! The cinnamon isn't everyone's cup of tea, but I really like it against the steel gray's blueish tones!

[YoungCR]

Exhaust sounds excellent, mellows out the rasp to a nice tone!

[Jdesign]

I hate the way S54's sound. This is an exceptional exception!

[Andrew]

Wow your exhaust sounds amazing.  Is it raspy at all?

Thank you!! This setup virtually eliminated all rasp. I installed each component one at a time and the resonated X pipe seems to be the main contributor to the tone / rasp elimination!
