Engine Drivetrain 1st Gen Cooper S Most liked posts in thread: Quieting down an RMW exhaust

Thats the most Sissy thing i have seen you post in a long time dave.
My car is not that loud and you know it.
Maybe thats a consideration.
What you really should do is call coast fab and ask if they have any "damaged" parts and get one for a discount, or do what i did and run a miltek back section a cat and a JCW resonator..
its not that loud.
Problem also is one persons quiet is another's loud.
In just like Geriatric Dave here.

 

^^^ Wow welcome back buddy <- wrong finger but you get the idea. :lol:

 

^^^^^^ I have so many replies that are not M\A appropriate. :devil:

 

The Milltek is my nice and quiet (wife approved) exhaust and it connected to Jans RMW street / Shorty header.

If I want loud I put on my custom cat back straight pipe exhaust.

 

The best way to quite that exhaust would be to remove the long tube RMW race header and exhaust and sell it for a RMW shorty header and a Milltek.


If you are on the RMW board someone will buy your setup.

 

mate the Milltek to it...............that will do it

 

Here is an article with some good pointers.....

I have a great idea........take my one ball mod oem system and give me your system!

 

Split cans will do it, the Milltek option is the best, I have the JCW, but it goes from 2.5 to 2.25 at the split (I have a 2.5 mangaflow up front). I'd like to go to a straight exhaust, but at 250hp the group 4 straight exhaust was too much drone. I'll eventually go coastfab or something else straight through, if I hang on to my current MINI.

 

The invidia is pretty quiet. I have a gutted cat, no cat converter and it doesn't drone, and very quiet low bass

 

look at my build thread in the exhaust video portion.

(i can dig it up on request)

granted I also have a turbo in there that muffles some,

but!

1x vibrant ultra quiet

2x magnaflow straight through mufflers.
(1x same side in and out, the other is a center inlet, offset outlet)

run in same configuration as a stock exhaust

It is quiet as hell, and only straight through mufflers (perforated tube)

serious sound reduction until you really get on it and not too much back pressure. (we are talking stock volumes below 3.5k rpm)

 

Depends where you live but I got a possible trade for 10 month old invidia cat back. Resonator was removed but I still have it.

 

Huh?

 

I know Colin and I have out for rides in his car in OC CA.

He is busting my stones, it's all good.
