1991 7 Series Performance Upgrades???

My friend just picked up a real nice 91' 740 something...anyway I was wondering if there are any upgrades that can be done to the exhaust and intake.. I have done a little bit of looking and havent found much except performance breaks....Thanks for any advice

google dinan they are a bmw performance tuner

Good luck finding aftermarket parts for a E32. There out there but they are very far and few. My friend has a 93 for almost a year and hes just came across some lowering springs for it. Other then mybe a engine chip or you could find a bolt on muffler for it good luck finding anything worth your while.

well u can do some upgrades to the exhaust pipes as long as u don't mess with the 02 sensors,besides it'd be good to get that heavy baffle off the end of any bmw. Their exhuast system weighs alot mainly the older ones.As far as intake if it was a 6 cylinder i'd tell u a few upgrades but i dunno much on them V8's.
