NICE! Dude that sounds so sick! I'm glad you found something you like man.

I'm also guessing it didn't really cost much either, which is one of the best parts of going custom. Also awesome that it doesn't drone much. I like your tip selection, looks mean!

If drone ever gets to you, try playing around with some strategically placed Dynamat. Not sure where it would help best in the roadster, but in the M coupe it helps in the trunk. And the stuff is lighter than most people think, so adding some of it isn't bad at all considering the weight you saved by getting rid of that brick of an OEM muffler.

More videos!

Thanks Man... There really is not a bad drone at all so I don't think I'll have to mess with the dynamat but thanks for the tip.. All said and done it was $615.00 and The cheapest exhaust I found so far for the Z was $550 not shipped or installed.. So that's a good deal .. My buddy has a 650i we are going saturday to have his exhaust done ...I'll def, do some more vids from inside the car next time...

I have the same setup, for about 3mo now. The sound is amazing for the price, I guess I got lucky though there's a great muffler shop here in Fort Worth that put it on and had tips available all in it probably cost me around $300 for everything.

I picked up the muffler on amazon so that probably saved me a bunch. the part it replaces seems more like a resonator either way its after the o2 sensors so it runs fine.

Hi there,

It sounds great on the video! I'm thinking about doing the same thing on my z4 currently have a Stebro which is to drony between 1500 and 2500rpm.
Can you make a video of the sound inside the cabin with the top closed?

Definitely agree with the other posters. Amazing sound. I just found a local shop that does custom exhaust. I'll have to check them out first and get an estimate. I'd like to be able to get it for $300 like Oazix.

also source some tips, they ended up being almost half of the total price at the exhaust shop.

Any advice on muffler tips? Which kind? Where to buy?


EDIT:
Just watched the vid again. I can't get enough of it. I can't believe it only cost $600. Sounds awesome.

I just removed my Stebro exhaust and drove it without
It drones even more then with the Stebro... Wonder if i put 2 pipes on it it will drone as much? (Muffler Delete) in other words how much drone will be reduced by installing the Magnaflow muffler instead of the resonator?
