So, my parts from Hahn finally came in, and the question is a simple one (I hope):

Out of FMIC, charge piping, CAI, DP with swappable cat and straight pipe...

Can any of these be put on without a tune? And yes I know, I could go put them all on right now, but I mean without hurting performance, screwing up trims, or in general harming my car or its current efficiency, since this is my DD.

Or, do I have to just save up a bit more, and wait for the tune?

[edit] And yes, I know the CAI definitely can't go on without a tune, but full disclosure seemed the right thing to do.

 

You could easily put them all on without a tune

Only item that will really affect your stock tune is the CAI really

That must have been an expensive purchase from Hahn

If they hadn't discontinued their exhaust, it would have been more, but it's whatevs.

Haggling is your friend, which is why I batched the order together, so I'd have some leverage.

I thought about Treadstone, but it just didn't fit with my overall plans.

Unfortunately, getting the pipes and intake powdercoated the right color took FOREVER.

But it looks **** (color-matched to the car, sport red tint coat)!

 

They are releasing a new exhaust
