Yea they legal in CA, just don't mess with the cats and you'll be fine.
Megan the only bolt on exhaust with quad tips for our car, I don't like their tips so I'm going custom, muffler delete + 3.5" tips next week.
So let me get this straight. Besides just having cooler sound (stock is nice to begin with imho), by installing megans I do get at least slight improvement with HP or at least it feels like it?
I am literally in the process for signing paperwork to get 2006 M35 with 89K on it, which from what I have checked is in a very nice condition. Right away I wanna keep it simple, legal in CA and add a tad bit of pizazz. Like:
1) Putting new set of NGK Laser Platinum spark plugs
2) Changing to Z-tube and dropping in K&N
3) Motordyne Plenum
4) Megans axle back exhaust + ?mid pipes + ?Y pipe + ?HFC
5) Is it worth tuning? What about UpRev?
Now I'm not sure about the point 4. Should I do just axle back, should I do mid pipes/y pipe/HFC as well? I don't want it to be a money pit. It's a daily driver. Should I even drop that much money in exhaust? I just want it to pull and as be peppy as (or a bit more) my friends 06 G35. On a test drive it seemed a bit sluggish comparing to G35. Any wisdom would be appreciated
