Dunno if thats really a good modification for you as a driver...Unless you need a higher top end speed youve just killed your low end torqe.(Guess you a motorway speedster=D not a drifter or curcuit racer)

[calvinsb]

not necessarily. i've found there's still plenty of torque for all the drifting i need to do :)

why show your face? i prefer looking through the front window with camera

Which # is that Magnaflow? I think it sounds pretty good and would definitely have one of those fabbed up for my 325.

[SWORDMANSTR]

that sounds really nice, i think that's what i want my 325 to sound like if i get one pretty soon!

@millakilla Actualy read what these guys can explain 4 u :) goto ww(Dot)automotivehelper(Dot)co­m/topic163228(Dot)htm And read the reply's, That will explain it to you nicely I hope.

@millakilla (Not that I trust all these dodgy websites that support your theory) But you are partialy correct. I fully understand the exhaust sensor and what it does. But that is just a electronics perspective(that doesnt take into consideration other detrimental factors that an exhaust is made to compensate for), and if you read carefully has very little to do with low end rpm exhaust release. "Note, not all exhaust systems are equal" And the explanation is far to lengthy.

[millakilla]

@tachi203 It has a lot to do with the exhaust, the various sensors that are connected to and/or dependent on feedback from the exhaust, because a reduction in backpressure lowers the amount of fuel needed to produce the same power, which is why you get a horsepower and fuel mileage gain... You clearly don't have a good understanding of how any of this works. Google the term "exhaust torque myth" and you'll most likely get a lot of other sources telling you the same thing I am.

[tachi203]

@577newname Sorry I never noticed your comment :( , I completely agree. It really should not make much of a difference at all as performance exhausts have not been known to change a car's power by more than 2-25 hp except for in out of the ordinary cases where the exhaust was/is restricting airflow or completely lack thereof back pressure causing an adverse effect.

[tachi203]

@millakilla air/fuel mixture? Whats that got to do with an exhaust? aside from burning the catalac converter(if you have one) or the density of the air?. I'm talking about fine tuning/flow restrictions and pressure effects(Or lack there of) and heat transfer. Which are the main aspects of a exhaust system. Depending on these factors in the design of the exhaust itself, it can vary what and where the optimal increase in performance you will get from an exhaust system.

[millakilla]

@tachi203 I know this is a really old comment, but performance exhaust will not decrease torque unless your car cant self adjust its air/fuel mixture... which typically isn't a problem on any BMW made within the last 30 years unless theres something wrong with it.

sounds great dude. i have a '95 and want to get this. how much was it?

[Lastspark]

Meh, sounds rice.

[longertrax]

great engine, i can see you baby that thing. look out for my godspeed exhaust movie coming soon.
