How you liking it?

Loving it overall - just wishing cold starts were a bit quieter.

Was going to get some sound clips, but got a lovely low coolant warning as soon as I cranked it up today. Have to get to BMW tomorrow and pick some up.

How much louder is it than stock on cold starts?

Much louder lol l - it’s mainly the additional bass

Here's some polished tip action that I recently added. I purchased this system originally with the black tips, the polished tips I ordered directly through Dinan and they're lightly longer.

I don't find it that bad at all lol I have no worries of firing mine up and bothering any neighbors.

Can also skip the cold start by blipping the throttle or putting it in gear.

Yup that’s what I do. Crank it and throw it in reverse/roll it out of the garage while the loudest part of startup is going.

When in sport mode and the exhaust pops really loud, do you hear a vibration under the car? I was thinking it’s just the valve rattling a bit but not sure.

No vibrations here. I did have to make sure to manipulate the hangers and such properly as there was one point where the midpipe was pretty close to the heat shielding and I could get it to make a noise by shaking the pipe. Got it moved to the proper place and I get nothing.

And yeah some of the pops are great haha I've had a couple of loud bangs in a hard acceleration and in high rpm manual downshifts. Just enough for my tastes without sounding like I've got a crackle tune lol

Totally agree. The exhaust is exactly what I wanted when driving. Sport mode is amazing.

There’s a certain throttle point when you’re in lower RPMs where you can get a controllable, consistent burble too. And yeah some of the bangs are definitely smile inducing.

I’ll check on the heat shield. Thanks for the suggestion.

Pushed the heat shield out around the midpipe and definitely seems to have helped the rattle.

Installed mine yesterday. Sound is great. Cold start is a bit much, but I guess you have to make compromises. Quiets down pretty quick.

One weird thing is after I finished the install and went for a drive/listen I was getting a lot of smoke when I would come to a stop. I can't decide if it smells unusual (aka sweet?), as I never really sniffed the exhaust before. I hope its not a blown headgasket, just seems quite strange to be right after swapping the exhaust. My coolant is full, I guess I will have to keep an eye on it and see if I'm losing coolant. Maybe there is some kind of coating on the metal for storage/shipping that is burning off.....?

More than likely the smoke you are experiencing is just the muffler packing bags burning off. Romp on it for a half hour getting it very hot and they will totally burn away.
