Hello everyone,
I have been shopping and from the looks of it, there are many people who have made performance mods to their M37's.
How much HP & torque will the following add?
Cold air intake
Headers
Exhaust & mufflers
Chip
Are there some of those you would not do?

My m37x is for the street only.

Thank you!

You would be looking at around 330 to 340 HP at the wheel with bigger injectors & tune

One I wouldn't do? Chip. I don't believe in them. You need a proper tune by someone who knows UpRev.
