BMS Catless Downpipe + Muffler Delete (*VIDEO*)

335Vlad · 02-13-2014, 12:35 AM

I gotta say this combination sounds great. But the only problems are the drone, and smell of gas.

The whoosh of the turbo is really pronounced now as well. Also a lot more popping and all kinds of other noise spitting out of the exhaust, you can hear the popping/backfire at the very end as the car downshifts during deceleration.

dam thats some ultimate noise making machine

SgtGoldy · 02-13-2014, 03:05 AM

Not a fan imho. But glad you like it man, its just a bit too loud for my taste. Also VDC off in the snow? Never driven in the snow with my BMW but that seems brave lol. More power to you brotha, I don't have the balls for that.

That's not VDC. My wheels don't have TPMS at the moment so it's giving me an error.

Sweet jesus! That car sounds like god gargling with sea water through a trumpet.

If you ever drive your BMW in the snow you will realize that in town it is better with VDC off. Getting started from a start with VDC on is terrible.

On the other hand, BMW does have some of the best VDC I have used. Lexus, Infiniti, and Acura not so much...

OP- Not bad, a little too loud for me but it does sound nice.

Mardio · 02-13-2014, 12:20 PM

Very loud, to each his own though...

335Vlad · 02-13-2014, 12:50 PM

It's definitely on the loud side, might have to reinstall the mufflers back. But it sounds so aggressive at the moment

335Vlad · 02-14-2014, 09:45 AM

Anyone know if the smell will continue or is it just a temporary thing?

You are catless so of course its gonna smell you don't have your catalytic converters lol.

And damn that is a LOUDDDD exhaust!

TopBack_Mack · 02-17-2014, 09:42 AM

Tearing up these Brooklyn streets. That is loud....is the smelling slightly going down as you break in the dp's?

AlpineSwift · 02-17-2014, 09:54 AM

You'll get used to it eventually. You really need to tune the car for the DP's because you may in fact be running a little rich now which would account for excessive hydrocarbons reaching your nose. There is also the possibility you have a leak at the flange connection to the stock exhaust...

HouseN54 · 02-17-2014, 11:59 AM

this exhaust is not loud at all, my old s2000 fuel pump was louder (im not kidding either) this is the same route i went except with raceland dp and its really deep

Hartge · 02-17-2014, 03:02 PM

techmaster05 · 02-17-2014, 06:30 PM

if you had black window trim...

man oh man... #pantydropper

JDane07 · 02-18-2014, 12:13 AM

Sounds great to me, you have my approval

Although I'm NA (but catless) I can say you get used to the smell and the noise. I don't notice either really anymore, but the people around you definitely will.

Have fun!

Black trim and tints coming soon :P

secretsquirrel · 02-18-2014, 08:01 AM

I don't mind loud too much, but there seems to be a lot of resonance going on in the cabin. My speakers are vibrating on my desk.
