It's 6kg lighter than my old Milltek (24.5kg vs 18.5kg), although it has 2 mufflers and larger diameter. The pipe has a 1.5mm thickness in both cases ! At idle and under 3000rpms it's very similar in noise to Milltek, then it gets much louder gradually !
PS : Made a software update and now the car pulls like crazy but couldn't measure anything since it was raining all these days !
MikLSP:
That looks like a fin job on that exhaust and 6 kg is an impressive weight reduction!
rex:
Very nice! :happy2: :congrats:

Yes indeed. Also, the exhaust piping is myuch "straighter" and is a true 3" which only uses straight pipe and elbows welded together. Milltek uses bent piping and in 3-4 places I've measured a reduction from 2.75" to 2.65". Knowing the smallest section gives the flow the increase in sectional area from 2.65" to 3" (outside diameter) is about 28% (calculated on the inside) !
