I’m the SimpleCarGuy and in this video I remove this old hacked up stock exhaust and install a brand-new stainless-steel cat back kit making my BMW 335i sound like a sports car again! This old stuff was straight piped after the resonator and sounded awful at higher speed, so let’s get rid of it, install the new shiny stuff and see how it sounds after!

With everything out of the box, we can see what comes in this kit and also see the quality of the bends, welds and craftsmanship. I must say that I am very impressed with the quality here and CANNOT wait to hear what it sounds like once installed. Stick around and you won’t be disappointed! Of course before we can install this exhaust, we have to remove the old stuff. To be safe, I put the car on 4 jack stands and couple extra ones in the middle to help me support the exhaust and provide extra safety. If you’d like to see this process in detail, check out the video in the top right corner.

Also, while here let’s not forget to plug up that vacuum line that’s not longer needed.

And there you have it guys, it is not fully installed and ready for the road. So, how difficult was this to install? I hope I captured the difficulty level in the video and it did take me almost 2 hours, but I would say if you are mechanically inclined, it is not impossible to do this safely in your own garage like I did. It looks as good as I expected installed on the car. Finally, let’s go for a drive and check out how it sounds.

Well, that’s all I have for you today and I must say I’m very happy with this exhaust. It’s not overly loud, but still produces a deep growl when you want it to. Most importantly for me, my car no longer sounds like it’s missing a muffler and is much more enjoyable to drive at higher speeds. Now that you know how to install an exhaust system, why not check out how I installed wireless CarPlay in this 10 year old BMW?
