R53 catback on my R50
This is a loooooong overdue post.....sorry for the delay Adam, Ken, et al.
Many moons ago (may be a couple years ago) I contacted ALTA about the possibility of them producing a version of their R53 catback for the R50. There were no plans to do so, but seemed intrigued by my interest. I said I thought the single-sided MCS exhaust would fit an MC with just a few mods at the rear of the vehicle and offered to do it myself and report back with results.....again, sorry it took so long, but here ya go.
I LOVE IT! The sound even attracted attention at the recent Phil Wicks event at VIR.....one MCS owner wanted to know why my MC sounded better than the rest of the cars out there. Opinions are subjective, of course, but you get the idea. I think ALTA's description "The exhaust note is pleasant and lively at idle while giving a sporty, throaty growl under hard acceleration. All of this without annoying resonances at high idle or while cruising the interstate!" is spot on!
I tried a few MC exhausts and was unhappy with most of them -- mostly due to sound quality or quantity and in-cabin resonance -- and then I realized there are a number of single-sided MCS exhausts that were probably more thought out than those I figure are built mostly as an afterthought for the MC. The R50 and R53 use the same manifold and their exhausts use the same center tunnel and the same central hangers/mounting points. The passenger side can on an R53 (or the single rear can on single-sided R53 exhausts) sits exactly where the R50 rear can sits. The only things I had to do were 1) modify the hangers for the rear can and 2) cut off the S-shaped tail pipe (which routes the exhaust to the R53 center exit) and weld on a much shorter tail pipe and a tip to exit through the opening in the rear apron of my R50.
The fit is great! The sound is great! It weighs less than it did before I cut off the longer tail pipe!
Thanks ALTA!

I love the fact that guys like you are putting real thought into the MINI aftermarket.....just wish there was more of a market for MC-specific stuff. Oh well, the cars are so nearly identical that many of the MCS bits fit.....or can be made to fit if you take the time to noodle it through properly.
Since this thread is posted on the Cooper S forum, I'm going to put the rest of my comments (if I can think of any), pics, whatever, in this thread over on the non-S forum.

Yeah they can be a bit of a PITA. I use a 11-12mm open end wrench under the cable then twist. Generally pops it right off! Feel free to ring me or my tech team if that doesn't work. Did you make it out for the airshow?

MCS Slower accelleration with CAI ?
03' - R53 6 SPD.
I have an Alta 17% SCP and belt, Alta CAI, and 1 ball mod.
Before I added the ALTA CAI, I had phenominal accelleration using OEM Box and K&N filter. Like 0-60 runs in just under 5 seconds at upshift to 3rd gear.
Seems now I have slower 0-60 runs and it is not as strong.
Why would this be possible ?

Some time ago, I had one step colder plugs, but swapped them out for hotter BOSCH Platnm 4's, Maybe I need to go back to colder plugs with a CAI ?
Each Mod made to an engine/suspension can enhance or defeat another and from my experience with racing an BUDWEISER Anheuser-Bush Sponsored AMC Javelin ( Exact duplicate like Mark Donahue's ) in NH, I may just have to find the correct combination for my particular application.

BTW: Until I purchase one of your ALTA intake hoses I still have the OEM one. So instead of using the #3 hose clamps, I used CV Boot Joint loops, they fit nicely into the OEM collar grooves because they are almost the same width as the OEM hose clamps.
Thanks for the help.

I installed the alta bov and the check engine light came on after a day. I was wondering if there is any way of seeing what the sensor is coming up for without taking it to the dealer. I wanted to make sure if it could be the BOV or something else. Also the cel did go off for a short period of time and came back on again. Please Help....

If all looks good still, PM me for my cell# or provide your daytime number and I will ring you to discuss. Happy to help!
