Firstly, hi N.A.M family, i'm Erkin from istanbul..

I have a mini cooper(2003),
I took Cooper s bumpers for my cooper so i will change my muffler type,
it will be at the middle, there are 2 alternative way,

first one; adding a pipe to my oem muffler and lay it to the middle,

second one; taking off the oem muffler and spare tire then putting a magnaflow universal muffler(pic-1) at middle like pic-2.
If a choose second one, Will i meet with a back pressure problem or another? Willi i get more power?

Thanks for your valuable answers.

Help me please...:(

 

Just going to point out you drive an 03 the photos are of an 07, in the 03 the battery sits exactly where you say you want the muffler to go, in the Cooper S, in the Cooper you have the spare tire there.

You have to ethier do a one sided muffler or atwo sided option, if you're going to keep the same skirts they have to meet in the middle or you can go with one of the options that has different skirts, I suggest you do a search and get a little more info.

 

Wow, Istanbul ! I guess these little Coopers are everywhere. Welcome!

I wouldn't think there would be a problem, other than you'll have to lose the spare tire and fabricate some brackets of some kind. You'll have to cut and modify the pipe so it runs over to the new muffler. I don't think back-pressure (or lack of) will be an issue.

 

I was thinking he had a Cooper (MC) ? Battery is up front.

 

Yes i have i cooper(non s), battery is at front, spare tire is at middle but i take out it And i take mini cooper s bumpers, there is not problem on mounting....

i want to make my egzoust system like 2007 mcs,
Will i meet with any problem at pressure? Will i get more power_?

 

Less bends=less pressure, less pressure = more power (in most cases) and just about anything will get more power than stock.

 

i trust you, i will make this on saturday...

Is there anyone who want to make different explanation, i'm attending on...

 

Take a look at the exhaust shoot out and exhaust referance thread in the Perfomance:drivetrain forum, MCS based tests but it will help you get a deeper understanding of general exhaust concepts.

 

Thank's i'm looking now...

 

Is there anyone who want to make different explanation?

 

you dont like me:(
helpp...:(

 

Hmmm,

Muffler design is very complex, the length of the pipes, correct amounts of back-pressure and then tuning the sound all involves a lot fo expensive research and development.

Simply hacking off the end of the current system and placing a random back-box on there may, or may not, have desireable effects.

You may get it absolutely perfect first time out or you may get a drop in power and/or driveability, you may get the exact sound you are lookign for, or it may sound like a riced-up Honda Civic.

It is impossible to say.

Dyno it now, hack the system together how you want it, then dyno it again.

Also make notes as to how it drives now and compare them to the 'after' impressions.

Good luck !

 

thanks

but these r my anxieties already ,

 

Exactly !

It is pretty muich impossible to say if your idea and design will have a good or poor effect on the car.

Even one design of back-box vs another will have a different effect.

I say dyno it, hack it about an re-dyno it, then post up the results.

 

like this...

 

There is no one on this thread who can tell you exactly how this is going to work on your car. I wish you the best of luck and hope that you will tell us how the project ends up.

Good luck and Happy Motoring!

 

you r right

Help me.....

I will tell the result to you..
