What is the fix for the alta exhaust and the USS? I have put a 1/8" spacer on the back two holes of the front brace and it still rattles.

 

Perhaps someone with a alta system can chime in . I've never seen one so I can't help you at this time.

After one install of the Alta, we changed the leaky motor mount, and also put in Power Flex bushings in the lower motor mount. It fixed the problem for our customer.

 

Installed my USS tonight - on jack stands - had a small air drill so I had enough clearance to drill straight - no problemo. Easy install in about an hour including cleanup.

This thing truly is incredible. I have a stock S sport suspension - no other suspension mods. I took the car out to my closest nasty off camber rough pavement S curve. And it was like I was ON RAILS compared to before. Now I really understand what the whole "go kart" handling thing is all about - I was blown away. You can feel the suspension doing what it's supposed to, instead of fighting off the gyrations of the chassis...

I was highly skeptical. How can 10 lbs of aluminum make the kind of difference everyone has described (even if it does cost $350)???

Well, I'm here to tell you, IT DOES. WOW.

 

Ain't it fabulous? I've been preachin' the USS gospel for the last year.I think the USS should be the first mod a cabrio owner does to the car. I'm suprised Mini has'nt made it standard equipment. Enjoy riding the rails!

 

...mine's been hanging in my garage since last June...

 

Pourquoi?

Er, I mean, Why?

 

Just do it!

 

Yep. I'm glad I did it first - I think this and the adjustable rear swaybar I have coming will give me what I'm personally looking for suspension-wise. And a whole lot easier and cheaper than many quixotic adventures...

 

Its porque. You can tell you don't live in the peoples republic of Mexico California.

Want to Sell it?

 

sure

 

um, French?

 

Oui, er..., Si, er..., Da, er..., whatever.

 

I installed the USS that was removed from my wife's cabrio on my car this weekend (we pulled it off her car last summer since she grew tired of the interference with the MillTek). No issues with the inserts this time around - I bought a used right angle drill off eBay to be sure I had clearance (suggestion to M7 - don't include an 8 inch long bit to drill 16g steel! ).

Quick test drive. Clunk! Put the car back up on ramps and put two extra washers at the rear (already had one). Test drive = ok. BUT! Road trip to Baltimore to sell the wife's cabrio yesterday....once the exhaust heats up, it bangs on the front USS piece.

Is M7's official solution to add more washers all around? I hope that's not the case...it looks a bit silly already, hanging so low.

 

PGT, what exhaust is on the car?

 

Alta 2.5"

 

I also have the same problem with the USS and Alta 2.5" exhaust.

 

The USS is the best reason ever to keep the stock system (or one-ball) IMHO.

Has helped me make my exhaust decision.

 

well, for those of us with Coupe's, it's not quite the same now is it?

 

No problems with Borla Race...at least not with a front bullet glass pack resonator replacement

 

What part is the brace touching? Is it the flange? I am installing an Alta 2.5 and an OBX with a cat. I will be changeing the front flange on the Alta to a 2.5 v-band clamp. BTW the front Alta is 2.25 on mine. The v-band clamp should provide more clearance. Or you could have a muffler shop cut an re-weld the flanges at a different angle. Let me know what you find out as this is on my wish list...

Ciao for now,
Frodo

 

It was close to the flange and the OEM catalytic converter. I need to crawl back under to see what was touching since it's hard to tell unless it's done it enough to leave tell-tale signs. I might just remove the rear lateral piece altogether.

 

I'll infer from the deafening silence from M7 that this is indeed the case. Perhaps you can make up a special batch of matching parts:



In all seriousness, I realize it's impossible for any company to produce a product that works 100% of the time with other aftermarket parts (same could be said for all OEM configs), but I'm batting 0/2 here with two of the more popular exhaust systems out there. Add to that the M7 bracing is hitting the OEM cat and I'd say the tolerances are just too tight with no margin for error.

"There are no problems, only solutions"
-Peter/M7's answer to me at MOTD about this very issue

<patiently waits for a reply>

 

The silence is never deafening here at the headquarters, but we do work
hard and we can't hang here at NAM all the time...

We sold close to 400 M7 USS units last year and very few issues crept up
that was un-solvable.

If any of you have issues that needs my attention....... Call
I'm always available .....
