slide show of the pics from this project. IT IS DONE!!! only driven around the neighborhood to get it up to temp. immediate observation: the muffler delete exhaust I used previously and am using now isn't enough muffling... otherwise, I don't hear any leaks and I haven't romped on it enough to "butt-dyno" it....

finished up the M3 manifold/header swap on my ZHP. one significant poor assumption. I thought, swapping the OEM manifolds would only increase the decibel level through the exhaust a bit. wrong. its stupid loud. I am using a donor exhaust sys, that I previous had final muffler deleted (still has two resonators). it sounded awesome with the 330i stock manifolds. not so much now.
enjoy the audio and my 3 yr old's assessment.
going to try a vibrant flat black, dual output muffler on it - like Bryant put on his IR. hopefully, it will be enough muffler to take the rasp out...
love the comments from your 3-year old!!
i hope the vibrant muffler helps!
LOl she knows what she's talking about...
I guess that shows just how restrictive the stock manifolds/cats are...
I bet the Vibrant muffler will make that sound amazing. Stoked for the next video.
One wonders if BMW put those crappy manifolds on the M54 as a sound deadening measure as well...
yea, I am shocked by the difference in decibel level (considering the M3's still have large cats). hopefully that indicates some improvement in flow performance... will def put another video together after the next iteration of this project; which I hope to be THE LAST!
I still have my stock ZHP muffler if you'd like to try that as well/first/instead. PM me if you're interested and I'm sure we can work something out. :)Quote:

I wonder if my twin boys will tell me it sounds cool when I put headers on my car :scratchinghead
Headers with the TSE3 will likely be a pretty intense volume.Quote:
