Hey Guys and welcome back to the SimpleCarGuy Channel. About a year ago, I decided to upgrade the sound on my BMW Z4 and as the first step, I went with a SuperSprint resonator delete. It definitely made a difference and I got many more pop and burbles while driving, but OF COURSE, I wanted more. So, a few months ago, I ordered the sport muffler from the same company. I’m not sponsored by SuperSprint and I paid full price, the reason I picked them was because.. well, no one else makes stuff for this car. When I tool this muffler to a couple local shops, they all told me it would be 600-800 dollars to make the pipe between the muffler and the existing resonator delete pipe out of stainless steel. Since the pre-made stainless steel pipe was half the price from SuperSprint, I went for it. Unfortunately, it went on backorder and I had to wait a couple of months for all the parts to get here.
Finally, I have everything needed to have a full Cat-back exhaust on my BMW Z4. Meaning everything past the catalytic converter will be aftermarket and should sound much throatier and more aggressive. It will also allow me to start looking into some tunes in the future. Will the sound be worth the price? Let’s get all of this installed and find out together!
After getting the car up in the air as far as I felt would be safe, I still did not have enough space to cut the exhaust off with precision, so I went to my local shop to get it installed instead of proceeding on the driveway. Unfortunately, I couldn’t film as it was getting installed, but here is the end result! It looks great and cost me less than a nice dinner for two but now let’s see how it sounds. There are 3 different version of exhaust in this video. The first few clips I have stock exhaust, then you will hear resonator delete and finally full cat-back super sprint exhaust. Now would be a great time to hit that like button for YouTube algorithm and of course leave a comment down below letting me know what you think of the sound. Don’t forget, this a turbo 4 cylinder and not a V8!
