Also looking for an aftermarket ECU and or Acessport to make tuning a tad easier. I haven’t found anything yet

 

any idea on the weight difference?

 

They felt relatively equivalent in weight. I still have the original one, which I can weight but it wasn't something that crossed my mind at the time.

 

This sounds too good to be true haha. I had just about given up on power boosts for my non-s... How was this install or how much did you pay a muffler shop?

I have a muffler delete right now and this makes sense, it sounds way better but it definitely feels restricted somewhere. Let me know! Thanks

 

It looks like it doesn't fit on my '13 cooper... I just got so sad haha. Magnaflow's site says its only for the 07 to 11s... Anyone put it on a 12/13? Did they really change anything, its still an r56?

 

I did the install myself. You have to put the car into service mode to get it out. There is a great video on youtube that helps you through that. The funny part was that I was only replacing the oil filter adapter gaskets and my manifold was cracked. There was no way I was buying a new factory cat so I went for the cheaper option which was the Magnaflow assembly. In no way did I know there would be such an incredible gain.

 

I just did some research and could not find any differences from the 07 to 11 and my 13... very confused why it says the part is not compatible with my car. 49028 part number is compatible with years 07 through 14?? very confused now. This isn't legal in CA but tempted to buy anyway.

 

Any thoughts on my predicament?

 

They are different part numbers, but I do not know why. The exhaust manifold gasket is the same and a catless header covers 07-13 so it appears connection points are the same.

 

Ive's Mini: Does this Magniflow unit effectively replace the catalytic converter?
I am faced with replacing mine with a $3000 + price tag. I'm hunting down options and would love a performance boost too. I don't know if it's legal in Michigan, but my Mini may die soon if I keep driving with the engine light on for the catalytic converter :-(

 

Yes, the cat is part of this unit. The one I bought is 50 state compliant and good for California emissions. This is the way to go. There is no downside. I was not going to spend that insane amount for an OEM unit. I bought this because it was a cheaper route. I had no idea that the performance gain would be so great. I called Magnaflow. They said it indeed flows better and has a hi-flow converter, but they could not give me performance numbers because they never dynoed it to see. I have been driving my car for 150,000+ miles. I know this car. I am getting 3 mpg better and the performance is through the roof better.

 

Hey everyone! I just found this tread from a link in another post. After reading this post, and checking the web for Spring Booster related topics, I decided to check out what my '07 MINI Cooper was doing. I was a bit skeptical about the Sprint Booster



By using my Foxwell NT510 scanner, I was able to look at the relationship between the throttle pedal signal and the throttle actuator position. Result: The throttle pedal is instantaneous and that's clearly visible by the change in readings on the scanner. the throttle plate on the other hand is not all that quick. From full throttle to full open, it took 4 seconds. Wow!


I may have to get a sprint booster and check it out.

 

Wow, I would love to see the difference with a Sprint booster. Please let us know if you get one!

 

I've had one on my car for 150,000 miles. It is awesome!

 

Not necessarily anything wrong with Sprint Booster. The throttle pedal is only a request; the ECU controls the physical throttle.

 

Absolutely correct, and it sure takes its sweet time.

 

This is tempting. Regarding the two magnaflow part numbers which one is better (FED vs CA) and why?

 

It comes down to where you live and the emission controls that are required by the Federal government. California, NJ, NY and Connecticut are required to have California emissions. In those states you would need the CA version because it has the ability to curb emissions lower and stay compliant. Just about everywhere else has federal emissions and the FED version will be sufficient. It would have less material inside the cat. If you look at the sticker under the hood, it will say "this vehicle complies to the (model year) and complies to (FEDERAL OR CALIFORNIA) emissions." That is how you can tell which unit you need. If you put a federal emission cat on a California emission vehicle, its performance might not satisfy the calibration of the computer and it may turn on the the check engine light.

 

I can see the heat shielding in your photo, I took the top part of mine off to have a look. Does the heat shielding fit with the magnaflow one since the diameter is much larger than before? also how long did the install take you, I should be ordering this part in a couple weeks once I have time.

 

Yes, it will fit without issue. It's kind of a shame, because the Magnaflow unit looks so nice. The install wasn't bad as soon soon as you get it into service mode. Follow the youtube video that shows how to put it into service mode and it will be smooth sailing.

 

 

I accidentally bought a set of R56 S brake rotors which are slightly larger than the non-s rotors. They use the same brake pads. I bought the Cooper S brake calipers brackets and everything bolted up fine. I am using EBC redstuff pads with ECS Tuning braided brake hoses. I do not think you can do better than that for brake performance unless you are in a track situation. This car stops beyond good. They are fantastic! I think the stock Cooper brakes were very good to begin with. I am just one of those people that tries to upgrade where you can.

 

Ah ok, I might just get better rotor and pads, since the brakes are amazing, and I’ll definitely take a look into them. Probably crossed/ crossed & drilled rotors that’ll fit behind my 16 inch wheels

 

I had crossed drilled and slotted on the car for awhile. I then came across a post in an Acura NSX forum that gave a very good explanation for not using cross drilled or slotted and recommended a good set of blank rotors. I accepted his explanation and on my next brake job I bought a set of Zimmerman blanks. Aside from how cool slotted and drilled look, I don't think my brakes could feel any better than they do.

 

Anyone have a link to that Youtube Service Mode?? I have the exhaust manifold and cat replacement....Thank You!
