Alrighty, time for my review after having Eisenmann race mufflers on my e64 650i smg cabriolet for a good ... errmmm ... 1.5 months?
Mod virus was injected by Evil Grandmaster ala Bimmermod OKT aka Wilman aka Wilson. It all started in September last year where I first met up face-to-face (previously was only buttcheek-to-buttcheek so not counted) with the Grandmaster. Was studying with him a crazy idea of mine which I'll cover later.
My e64, bought brand new from PML in July 06 dressed in full ACS outfit, 21" type IV racing 2-pc alloys and AC springs, was due for more juice. I love the way all the ACS bits held together on the 6er, from the front bumper to the sideskirts, to the rear spoiler and most importantly, the exhaust tips. I didn't want to change any of that.
The exhaust note from the ACS mufflers were OK. It blipped sensationally, good bassy note, sexy V8 burble, no droning but I've always felt some degree of hesitation, some sort of delayed response from the moment I hit the throttle to the moment the fumes blow out through the rear pipes. It felt kinda like the mufflers were slighty choked. This was undesireable by my standards.
Did some research on the net, compared between Britalmann, Eisenmann, RDSport, Hamann, Supersprint, Magnaflow and etc. but was blown away by the construction marvel and exhaust note of the Eisenmann muffler. A big downer was how typical my e64 would look with quad pipes. I didn't want to look like a try-hard wannabe M6er, afterall, I didn't get my e64 cheap so no point degrading myself.
So here came the crazy idea. What if I removed my ACS mufflers, surgically separate the tips and have them joined onto an Eisenmann race muffler? Would that work? Would there by clearance problems? Would it align nicely in the arches of my AC rear bumper spoiler? Would it stick out too far due to the difference in size of the muffler bodies? Notice none of my concerns were about whether it's gonna be LTA compliant? :screwedu:
Tons of questions, no answers. Grandmaster took a look at my undercarriage....and then the undercarriage of my e64, and shook his head at the latter (phew!
). He had a worried look on his face. He wasn't sure if the Eisenmann tips would align nicely with the arches on the bumper, and I might possibly have to cut the bumper...which would really suck. We decided at the end of a long tussle that it wasn't a good idea. I should just stick to doing up the mid pipes and have the case closed. He made it clear that there were too many risks and unknowns and he didn't want me to end up buying something I can't use. Needless to say, I was a sad sad boy for the next couple of days.
Then it struck me one day. WTF? :furious: Life's too friggin short. I rang Grandmaster and told him to order a set of Eisenmann Race mufflers in for me. The rest of the next couple of months, you guys know the story. Ding dong here and there. Grandmaster not at fault, in fact he was buying ringing up checking on status of the delivery and all. End up, he got the e-race from Barry for me. Good guy.
Then the fateful day came. For the record, I was 20 mins late meeting the Grandmaster at Mans Exhaust. Needless to say, I paid for his meal and drinks that day. Grandmaster briefed the mechanics. They shook their heads in disbelief and satyed at me like I'm some kinda retarded rich punk with no friggin sense at all. I stood there watching helplessly as they jacked my e64 up on the hoist. Grandmaster pulled me away and walked me to the nearby coffee shop. He told me it was better if I didn't see what was going to happen next.
We had something to eat, and drink, and we drove to J4C nearby to see DV's 335i put on a new intercooler and downpipe. Then we drove to BHP. That took my mind off the work at hand but I started to wonder WTF is Grandmaster up to....
We eventually got back to Mans at around 3pm. The e64 was still on the hoist. The ACS tips were still on the muffler. I couldn't believe my frigging eyes. Grandmaster was dumbfounded as well. WTF? 5 hours and nothing done????? We rushed over to the car only to see...hmmm....MY GOD!!!! The ACS tips have already been welded onto the Eisenmann race mufflers!! We were over the moon. The mechanic even sprayed the rear end of the muffler black so that it looked exactly like the original ACS muffler. Dang! Thats what I called ingenuity!
Mannn....I'm tired typing this. I need a break.

So RAW, AVA will never approve for consumption! Now I have absolutely no disguise coz the exhaust note is distinctive even at low rpms. BUT....still it idles nicely with a slight humming noise (generated by Grandmaster) which is still very decent.
