My Mini came with the upgraded JCW exhaust so getting a new exhaust was always out of the question. I hated the idea of having two catalytic converters within a foot of each other though. Heck, I hated even having cats but that’s a different story.
One day after looking at some exhaust parts I got the idea of trying to fit a catless and resonator free midpipe to my setup. I was able to get a UK spec midpipe from Miltek for sale online and it was exactly what I was looking for, no cat and no resonator. The plan was to cut out my stock midpipe and replace it with the new Miltek one.
I found a local exhaust shop and after 3 hours, my exhaust hack was complete. There were a few hiccups but nothing major. The JCW pipe width was the same as the Milteck pipe, 2.75″ so to make a slipfit connection the new pipe had to be stretched so the stock pipe would, well, slip in.
I decided to get the two pipes welded at the rear axle. Originally my thought was to have it a slipfit back there but realized I wasn’t going to be switching pieces around.
The last road bump was the heat shield. Thankfully that material is flexible because we had to bend a bunch of it to stop the pipes from rubbing, again, no big deal.
All in all, I love how it turned out. I have the JCW Bluetooth system so if its too loud I can just close the flap. After starting it up and taking it for a drive, loudness isn’t going to be an issue. It’s a little louder than stock but the pops and bangs are more frequent and a bit louder. I love it!
Eventually I will get a new downpipe but for now. I love how my Mini sounds!
