What did you do for your ZHP/ BMW / MINI today? #2

[AggieBlake]

Did you buy the exhaust new or found a used one?

Found a used one on e46fanatics from a guy that decided to install a supercharger and open headers. Didn't need this anymore with the direction his build was going. His loss was my gain. I scooped it up a few minutes after it was listed. There were multiple people in line behind me by the time it shipped.

The entire driveline feels noticeably tighter, and there is less of a "clunk" when I come on or off the throttle hard. I still have a cracked rear diff bushing to replace, so the clunk won't be entirely gone till that's done. I would attribute most of the improvement to the engine mounts since the stock ones had cratered. The stock tranny mounts were in decent shape. Overall I am very pleased with the M3 motor mounts and UUC trans mounts. I do not detect any increase in NVH... just a much tighter driveline.

As for the Corsa exhaust, it's like crack for your ears. Gas mileage will take a hit because you just can't make yourself shift before 5000 rpm. It's perfect. (Note: I've got it coupled to an AFE stage 1 intake which increases the sound as well). Also, I am amazed at how quite it is at idle and cruise. I was concerned that my wife would be upset - she does not like loud cars at all. She didn't notice the new exhaust sound when I loaded the kids for school! Until you get on it, it's surprisingly tame.

That sounds great! OEM M3 tranny and engine mounts are on my to do list for down the road, glad to hear you enjoyed them (well, one of them, I'll stick with M3 over UUC).

Well, its time... X5///M tune is coming... Personal tuner will arrive tomorrow and then I'll flash the ECU file and have it sent out for work... Should be all done tomorrow evening... Can't WAIT for the addition of 85hp & 120 ft-lbs...

Like you need more power!! Hah. But why not as they say!

Well, I gutted the downpipes, so no more cats, and it now throws a check engine light. So the main reason for the tune was to get that turned off. They're also getting rid of the cold start, which will help quiet her down in the morning... The power and torque are nice additions though... Lol

+1. Wow.

"ZHP is a garbage option anyway- just some cosmetic upgrades with a different cam and diff to claw back some of the performance lost fitting those hideous and heavy wheels. Any 330 with a 3.46 diff will smoke a ZHP every time. The whole Mafia thing reeks of childish behavior." - an e46fanatic
