Diameter of factory exhaust?
 

Does anyone know what the diameter of the stock exhaust is? Im going to be making my own custom exhaust but cant figure out what the size is.

2 1/4 on the old cooper. I wouldn't think that they would have changed it all that much but I may be wrong.

Thanks. I wanted to make sure so that when i ordered my piping for the one im putting on mine it would be the same.

check out realoem.com. it lists the specific clamp sizes when you look up the exhaust parts.

I just happen to measure the diameter of my as-yet-unmounted-Stage1 and the intake pipe is 2.25" (or 40mm for those thinking metric, vich is vat ze Germans vould know it as)

Thanks already looked it up and ordered the piping for my exhaust, tired of waiting for a company to put one out! Time to fab my own! Gotta love knowing how to weld!

Well, I took my MINI to a local exhaust place the other day to get measured up for a custom system I'm putting together and they measured it at 1 and 7/8ths inches. So almost 2 inches...

Thanks Texaspaul I went with 2.25 but I have a adapter for the piping so it worked out great.

so you made one?.. pics / videos by chance?

a few pics video to come soon. sounds great, still not finished with it yet. hobby shop on base out here has been closed for a while so i cant get her up on a lift. to take out my 2nd cat and resonator.

looks good. didnt expect a muffler out there. first ive seen

Thanks, yeah I ordered all the piping and the muffler myself and put it all together. It's good to have such a deep back ground with machanics and fabrication, thanks to the military. LOL. Just got to wait for a day that i can get it welded together. Its a MagnaFlow muffler, I found it online and figured why not try it out and see what happens. The sound is a deeper roar, unlike a lot of the round mufflers that put out that riced out angry bee hive sound. Im happy with the out come of my creation and experimenting. At least i can say I have a one of a kind exhaust.

Here ya go Iwashmycar, still not a finished product yet but something to go off of when I actually do get it all the way finished. It sounds a lot better when actually driving.

Finished it today. Full 2 1/4 piping from cat back.

I am very impressed with what you've done. Only had my car a couple of weeks but I was dismayed at how many little turns and crimps (not mandrel bent) in the stock - less than 2" pipe.

Man, I wanna move to Spain. Does every one there drive like that?? :thumbsup:

No Drew just me and a couple friends in the vid the BMW and the Blue R56s in front of me. lol hahahahaha the people out here that have mini's dont drive them except for to and from work their afraid to go out in town with their nice new cars!

If you pass anyone here you'll get tailgated to your driveway. I've been followed and yelled at countless times after passing people doing 10 under. Its so annoying, i just wish there were more long open roads here like the one in your video.

Oh god Drew the roads out here are endless on how long you can drive. there are so many to choose from. Twisty and curvy roads only thing that sucks is that the Spanish dont drive to good but at least they get out the way. lol and passing is like a religion out here. There are roads out here that make the dragon look like a mc donalds play land vs a theme park.

Car sounds great. Thanks for serving our country.

Thanks fritzoc and just doing my time now and cant wait to get back to home sweet home in Indiana so I can enjoy those country roads again. I like the PS R50.

I still wonder what it would sound like if I had a straight 2.25" pipe from the bottom of the headers (after the 1st cat) all the way back to a magnaflow or borla muffler.

Drew it might just sound like mine cause thats exactly what I did.

Oh I thought you did it from the 2nd cat back, not the first.

nope I cut right at the weld in front of the 2nd Cat. so pretty much from the hangers back is 2.25.
