1)It does not have a resonator
2) where the valve are opend it acts like a Mufler delete (90%) Have your resonator delete and have a cutout in your exhaust system or buy an exhaust system that let you have a semi mufler delete like afe exhaust |

PWG N55s have a smaller downpipe, but EWGs have the same size as the B58.

I'd be interested to see if anyone on a blind test can tell the difference between EWG and PWG exhaust notes on the same upgraded exhaust system... I highly doubt it.
I have PWG w/catless downpipe and MPE. it's got a great growl to it but what I like the most is that it's not intrusive in the cabin at all. With burbles disabled it would be tough for a passenger to tell I have an aftermarket exhaust - until I roll down the windows. MPE w/catless downpipe is what I'd do |

Even though the DP inlets are different sizes,the outlets are the same, the midpipe diameter is the same, and so on. The dp size is irrelevant for these turbos as long as you aren't choking it with a tiny dp.

So you don't attribute the exhaust tone difference to the DP sizing?

Here's mine on a cold start. Can someone post a 340 cold start so we can start comparing?

I think it's all in the OEM burble tune with the MPPK equipped 335/435 and the MPE for those cars. The M235 (comes with the MPPK as stock) and with the MPE installed is far more burbly, poppy, and aggressive sounding than a 335/435 with the same exact setup. I can't a difference in sound between a M235 and M240 with the MPE. I have a hard time believing the sound difference is because of the turbo outlet size or the different engine design which the only main difference being a closed deck block vs open.

Sure muffler different. But not different enough to create the huge difference in tone. You compare a straight pipe 335 and a straight pipe 340 and there will be a difference. Difference being: the DP. |

I posted a photo of the lci MPPSK muffler on the previous page. It's also plausible that some of the exhaust gas still passes through the muffler in sport, and the muffler chamber would still add notes to what we hear.

I believe the tone is due to the downpipe because when I went catless I could hear I was close to the b58 tone. (compared to older 335 catless videos I've heard) It's like comparing a m235i(EWG) with MPE vs older 335(PWG) with MPE. It doesnt have the tone nor crackles as the m235i. Which can only be attributed to the downpipe.
