total hp?

[jewbacca02]

Ok, assuming I start with an M5 2002, how much hp would i have after these mods:

Flowmaster exhaust
SLP cold air induction
RKSport headers
K&N FIPK
K&N air filter

Catback and intake together probably add 20hp at the wheels. Add headers and you got 23-25hp. You do know that SLP is the complete intake. You don't need that K&N stuff listed there.

An M5 2002 has what, about 200 horse out of the factory right? Well, the SLP cold air and the FIPK from K&N are both cold air induction kits. You can't use both at the same time. Both have about the same gains. However, the K&N FIPK is made for the 3.4 liter not the 3.8. With the 3.8 the 1LE elbow is needed to make it work. You would have a different sized throttle body. So, with either kit, you would have about 10hp gain. Now, with a flowmaster muffler, you would have about 5 hp gain. Not a feel-it-in-the-seat-of-your-pants gain, but a helpful one. As for the K&N filter, well, the K&N FIPK comes with the K&N filter, and the SLP cold air kit has cheaper paper filters. Either are close in gains. I'd reccomend the SLP kit over the K&N kit, only because I've heard and seen both, and I like the SLP better. To me, it sounded meaner, and it performed better, and they are both about the same in cost. Either way, it will run about the same. The SLP kit also looks nicer in the engine compartment. It has dual metal pipes, as compared the the K&N plastic tubing. For the headers, they have like 7 horse gains. They sound crazy mean, but from what I've heard, they aren't worth the cash. Good luck with whatever you choose. Don't let other members get you down with rude comments. Everyone starts somewhere. I'd say in total, with the SLP cold air kit, the RK sport headers, and flowmaster exhaust, you'd be around...220 horse. Not bad. [img]graemlins/burnout.gif[/img]
