MAD: New Product Release -G8x M3 M4 Axle Back Exhaust

Jax327 · 11-27-2023, 02:41 PM

If I would pair this with the non resonated midpipe, would there a lot of rasp and drone?

That would be this exact setup.

At first I thought it was in the inner right tip, but it's actually the outer right tip getting bent up as MAD pointed out (see screenshot).

Looks like they're getting you covered though.

Any updates on drone/rasp?

Less depending on what midpipe you choose.

Resonated midpipe - https://mad-us.com/mad-bmw-g8x-m3-m4...race-included/

Non resonated mid pipe - https://mad-us.com/mad-bmw-g8x-m3-m4...race-included/

One question I had thought of was the placement of the valve actuators.

I barely have any slack with where I placed my SST controller to where the OEM valve actuators are, I can't really tell if they're in a similar area to where the OEM ones are (they at least look like they're mounted more "on the top"/closer to the trunk than on the outside of the pipes.

What can I expect in this regard?

Curious on anyone has any more to say on this now that it's been a couple months since release? Devils41 any more thoughts?

Hey no issues with the exhaust at all now. I took care of the off kilter exhaust tip, I had a shop friend help put it back into place with little effort. MAD did reach out and they offered to pay for the fix but it wasn't necessary. The exhaust works as advertised and sounds great! Over all I'm extremely happy with the product and the customer service from MAD. To me it's rare to find a vendor who actually engages with its customers and works to make things right.

Thanks for the review, any noticeable drone?

Yes I do have some drone at highway cruising speeds (ZF8) in normal with valves closed. It's not horrible and I really don't notice it anymore. It passes the wife and Baby test so I'm happy with it.

Ok that's a bit concerning for me but hopefully it's not too bad.

I'd pick up the resonated mid pipe then instead of the non-resonated
