Anyone seen dyno charts of the Supersprint side muffler delete? Part no 244526 + side pipes 244613/244643.
I really don't expect any gains. However, it would be interesting to see if there are any losses of torque or power somewhere in the range.
The word is that this solution is slightly quieter vs stock wich is what I'm looking for. Local tracks have got additional requirements re noise :-(
Should drop a bit of weight as well wich is always a good thing.
