Went to a few places to install my Performance Exhaust. First shop wanted $125 which I felt was high for only cutting 2 pipes and mounting an OEM exhaust but was just about to say yes when he said I had to come back in 2 days. Second shop said $80 but then backed out stating my car was too low and he wasn't sure he could get it onto the ramps (even though he had boards). Third shop just shrugged his shoulders and asked if I could come back when his manager was in.
WTH is wrong with all these people?! So, I decided to just DIY. It's not hard. In fact, it's quite simple. So, for those of you that don't want to pay that BMW tax or don't mind a little labor, this is for you.
- Jack and Jack Stands
- 8mm, 13mm, & 17mm socket wrench
- Pipe cutting tool and/or Sawzall with metal bits. 14TPI suggested (thats teeth per inch)
- Eye protection
- Measuring Tape
Here she is. All new and pretty. Note, you get 3 clamps in 2 different sizes. The smaller one fits between the two mufflers.
Jack up the vehicle and secure with stands. Stay safe.
This is the approximate locations you will make the cut. The next image is a pipe cutter that can be rented from Autozone for free.
Also, just so you know what you're dealing with, here is the thickness of the SS piping.
Okay, before making the cut, measure where the PE needs to connect. I measured about 3 3/4" from the muffler.
Take that measurement to the factory system. Make your mark. Then take a piece of paper folded several times and wrap it around the pipe tightly. done right, it'll give you a perfect line.
Put on your eye protection unless you want this in your sockets.
Get that pipe cutter and begin cutting.
You can keep at it with a death grip. It'll take some time and strength. Halfway through, my brother stopped by with his Sawzall. With the right blade, it'll cut quickly. I'm still glad I started with the chain cutter. That made a nice score to keep the blade aligned.
Once the 2 cuts are made, remove 2 8mm bolts and 2 13mm nuts holding the stock muffler.
Put the clamps into position. They are on the mid pipe really to slide.
Using all your limbs (or a friend) hold one section of the new muffler up while bolting it into place. It will not be secure until you at least slide part of the clamp on. At this point, you may notice a nail in your left rear tire.
Get the other side on and start tightening the 17mm nuts. You'll have a little play with the clamps to help align the muffler tips. However, mine were pretty good.
If you did it right, it should have taken about an hour depending on how long those cuts take. Here it is all done.
That's all she wrote.
