Ok, I have a r2c intake with an uprev tune and am dropped on swift springs with some 20 in wheels. I have about 800 bucks to blow on the car. Was thinking of getting the midnight grille and then the rest on some type of performance part.

Was thinking of the Megan racing axleback, but realize there is not much performance to be had.

What would be the best mod? The tuner said he will re-tune for free if I get any more mods. Was thinking possibly a HFC but then not sure what brand.

Please give me some suggestions.

 

For 800 look for a cat back on here used, I would, But you may have to return after that?
I did all my bolt ons then tuned it, Not sure how it works if your tuned and add exhaust, Sorry

 

BERK Technologies makes a great HFC choice for your G37:



Here's a video of what your G37 would sound like with BERK HFC and stock exhaust:

Hotchkis sways is a very good investment.
