Hi Guys.
New here from Thailand, when i go down a steep slope sometimes my car come up with transmission fault, when i turn of the engine and start again the fault has gone, the car has been in the BMW shop, did a data check, nothing came up, it took 3 hours.
BTW my car is a 2005 525I SE E60, done 55.000KM and cost 60.000US$ a few days ago, yes for a near 4 year old car, you guys are lucky in US
Somebody also say that if i put exhaust system on each side i will lose HP, any know how many HP you lose?

Thx a lot

Can't really help you with the transmission, but for the exhaust, depending on which one's you buy, you can expect to lose about 8-15 hp with quads.

Hi
Thx a lot, think i will stay away from the quad then.
