Do you have any dyno results with logs showing this? I've always understood that below 750whp the stock exhaust is not a restriction and dropping it results in no power change.

Yes, no issues with fitment.

My car was even more complex because it is a E93 (vert) and has a ton of bracing under the car. Everything cleared just fine

I'd love to see some Dyno charts showing a 45hp gain from the stock to the VRSF exhaust.....pretty hard to believe. No way the stock exhaust is that much of a restriction....even on a modded car.

I've seen some stage 2+ FBI cars gain 5-7hp from an aftermarket exhaust....but 45hp?? 🤔

Wait, what? Tiago said that? That's BS, I barely feel a difference at 450 ish. Maybe on a ST setup pushing 700+

Our street muffler saves over 42 lbs over the OEM exhaust setup due to the single pipe design rather than the dual pipe. Dual exhaust setups add significant unnecessary weight.
ANY options for E93 ??
i have MMP1K and a lot of mods but stuck on stock exhaust at the moment (except downpipe)

I just ordered the VRSF catback race exhaust, it’s definitely my favorite out of all the clips I’ve heard

I'm guessing that if there was any actual proof...... someone would have posted it by now.

The oem exhaust systems seem to flow pretty well...

has anyone taken the race exhaust and added a small muffler or larger resonator to it? The only one I have seen was on a single turbo car, and the sound is different i would imagine.

I would love something in between the race and street exhaust.
