Only in one now GURE, sold most of it late last year, actually to buy my 330i with a nice profit. Thinking about getting back into China again since it's stocks seem to be hated now, only trade what's on the American exchanges.....RDT

Hopefully the ARMA exhaust will be as good as they say it is, I'm thinking of buying their headers so when you get the system can you take some good quality photos for me to see?

Thanks!
the headers are already installed on my car.. ill post more pics when the car is lifted up again for the arma midpipe and muffler install

i run a family business doing medical devices... i also head an investment company that deals with some securities and chinese real estate.. chinese stocks are highly volatile hence giving you high risk but high yield opportunity. most of them will have fabricated earnings but at the same time, they will still have high market value as they are chinese market based companies.. you cannot use a western method of analyzing these stocks or else they are all overvalued.. it is more on what goes on internally both within the chinese market and within the company itself..

Nice ******, on your businesses (you're one of the people that will drive the future of China) and advice about over hyped earnings, I've gotten out of a couple that started to be heavily shorted just because of that. Hope this Arma blower works out though I'm having a hard time on the exhaust being too restrictive. had a blown mustang GT 4.8L mod motor that pumped out 365 HP at the wheels with just the cats removed........RDT

Eisenmann might be 2.75.

You would be fine with any 3 inch piping exhaust back to the muffler with a free flow muffler
tks for the advice.. i figure i will give arma a whirl with their "specially tuned" exhaust.. i can get a 3 inch exhaust but in china, it is best if you stick with finished products.. custom work and quality isn't exactly a strong suit here..

still clearing customs, should be out by 30th. i did have a tech look at my car.. the secondary cats are very restrictive and does in fact have an effect on my boost as exhaust is unable to escape fast enough causing my car to run too rich. seems like it should make sense as my car feels constipated as i try to get my revs up.

there was a problem with the maf that caused my car's loss of power, they were able to fix that with a bypass software. the car drives much better now compared to my previous setup: 325i 6mt with pbox, eisenmann exhaust, kn filter. the boost really kicks in at 3k rpm. butt dyno, i would say it is much better than a 330i but sub par to a 335i. after all it is a 2.5 liter with supercharger vs the 335i's 3.0 with turbos.

the supercharge whine with the added speed is quite arousing. i ran the car with a/c and 33 celsius ambient temp so it should be faster as temps cool in a few months.

had a test drive on a "closed road" with a 325 auto with eisenmann exhaust and kn filter. we tried a few times but both car seems very consistent in results. my sc 325 is about 1-2 car lengths faster by the time of reaching 100km... the road was too short to go any further but the other driver said my car was pulling away more and more. overall it is no 335 but so far relatively happy with results.. the supercharger whine turns heads like no other... i don't think my 911 turbo gets as much attention.

yup that is my car with the new exhaust.. finally got everything fixed.. did a tune from the techs.. got all the af ratios right this time.. the car is now a beast... it is no m3 but for a 325.. with the supercharger whine the variable valve exhaust and waste gauge it is incredible... it feels very fast... i would say 0-100 in 6 or maybe even high 5's...

i put up a video for your viewing pleasure.. 0-140kph on a side road with 1 passenger in car..
