Replacement M exhaust - thoughts?

mark seeker · Post by **mark seeker** » Tue Apr 24, 2018 2:14 pm

I have been thinking for a while about replacing the OEM exhausts, what is the preferred route for aftermarket pipes?

I saw a clip of the BCS exhausts and they seem to sound lovely, an enhancement of the current exhaust with an audible shout, does anyone have any experience of these? I am really trying to avoid a drone / boomy soundtrack.

Any help / thoughts / suggestions appreciated.

Not sure if you have done a forum search but this could be worth a read viewtopic.php?f=9&t=76562&hilit=bcs+backboxes
Since the initial sport / prestige choice they now only offer the one option which i had fitted on my last MR currently now owned by Rally .
A good few other owners also have them too .
What i can say is i highly doubt any disappointment in any department with them & if you are tempted save yourself a wedge of cash & take a virtually new set off "mpm"

I have a pair of MM back boxes sitting in my garage looking for a home.

I’ve just purchased some Stromung back boxes. I had read good things online and may be worth considering.

Ive got a pain of Stromung backoxes, they sound really good!
Dont be put off reviews stating they are too loud or droning, the intial drone between 1600-2000rpm fades as they soot up, after 300 miles with them fitted its nigh on disappeared.
Plus they pop and bang on the overrun!

Can’t wait for mine to arrive now! Plus they fill the bumper aperture better than the stock IMO
