I have a question for you S owners....(I haven't got my car yet,waiting for '04 model,in oct )...when you look under the chasis,and you look at the exhaust system,you see that there's a resonator before the actual muffler...NOW THE QUESTION...If you bypass that resonator,(a cut must be made to the pipe,before the resonator,and a new piece added to link it to the muffler),and go directly to the muffler,will that help in performance,and sound?...Has anyone done this set up?....I won't have all that $$$ for new cat back system,so a new cat-back is out of the question........Thank you in advance.....MINISPIDER

 

NO ONE?....PLEASE.....I'M BEGGING NOW....

 

If anyone on this forum knows, it's probably RandyBMC.
Try sending him a PM.

 

i have mine done it's cost me $20 it's doesn't sound loud at all. i do notice a little more power.if you live in socal you welcome to come by for a test drive.

For starters, I don't know the answer for sure since I am not an expert. However, I always thought that the primary function of the resonator was in aiding suck air out of the exhaust ports of the cylinders, through 'resonation', or appropriately timed pulsatile air flow. Therefore, my thought was that if you bypass the resonator you would experience a power loss. In a well designed system like the MINI's, I would in fact expect a fairly substantial (as in noticeable) power loss.
Am I completely wrong???

I think you're right. Isn't the exhaust in the Cooper S an OEM of a resonator back exhaust system from Remus?

go here and scroll down to the bottom. thumper460 has done it. i plan on doing it monday.

i do live in so cal, can i try ur exhaust out?

 

Thanks for all the info,I just came from looking at all the Minis at the tower shops,here in Ft.Lauderdale,I've met very interesting people,and their cars are so cool!!!! ....(I had to get my Mini fix...since I'm waiting 'till oct for a '04 model)....The reason I asked the resonator question,is because I did it in my chrysler 300M,I removed 2 resonator and then I used a " Y connector" for dual pipes,and the results were very pleasing,sincce the system wasn't restricted anymore,I've got better soung,(deeper) and better performance....so I thought,may be this same approach can be done with the mini....any comments?

 

yes red03miniS anytime on sunday. i live in whittier, just email me.davidt2_2000@yahoo.com

 

If this modified exhaust works for you guys-
would you please post pictures of what it might look like?
And if you ever get it dynoed could you let us know what the results are?
Did it change your mpg rate at all?
Thanks

 

check out the exhaust mod in this article I posted at the end of this exhaust thread!

unfortunally,you will have to wait for OCT.that's when i get my '04 mini

 

my mcs is now one resonator lighter,and actually sounds very much like stock- just a notch louder. and burblier. i love the burble. unfortunately there is a bit more vibration inside (most noticable at idle). but.the car feels a bit quicker overall. that may just be my imagination. it sounds just sounds racier (did i mention the burble?). aside from the slight vibration, my only real complaint is the idle sound. it just sounds, well, funny. i guess it sounds like stock, but amplified. the stock idle has a kind of muted plastic putt-putt tone. mine still has it, just louder. kinda loud and yet restrained. anyways, i think it was worth $45 and it'll help tide me over till i get that nrp.
i'll try to get a .wav file tomorrow or the next day so you can hear it .
by the way, my bmp intake is for sale (see marketplace). it was a little loud when paired with the exhaust, so i took it off. interstingly, the exhaust seems even burblier with the stock intake.

now then. who's gonna be the first to keep the resonator and ditch the muffler?

Thanks for the update.....I hope you download the file, so we can listen to it. I will be doing the same set up when I get my car,and see the results.Thank you very much for the info....hey! about some pics?

 

as promised, a couple of in-car sound files. my apologies for low volume, poor sound quality, etc.

-civilized-



-like i stole it-

 

well crap. once again, this time with feeling!
if you listen close, you'll hear the burble when i let off the gas.

bb code is fooked. i guess by now you've figured out where they are. good luck. you'll need it. (considering the quality of the files, it really wasn't worth all this. sheesh.)

I CAN'T FIND THE FILE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!HELP !!!!!!!!!!!!!!!!!!!!!!!!

 

cut and paste the following into your address window: http://members.roadfly.org/bodinski/2.wav

i'll try to get some clearer files today.

 

It sounds pretty deep!!!!!!!nice

 

it seems to vary, but with the a/c on, it seems deeper/louder, and causes a noticable vibration in the car. especially at idle. the exhaust system actually shakes pretty hard. maybe the resonator is there to, uh, remove the resonance? maybe? i may end up putting a bullet muffler of some sort on the center pipe.
ironic. take one off, put another on...
