For whatever reason a lot of dealers don’t like chargepipes, but FMICs seem to be in a grey area…As with all mods, it’s a case by case basis.

Best overall- Helix
Best 5” core- ETS or ER
Best value- VRSF 7”

You cannot go wrong with any of the above choices.

Edit: Ozinaldo- regarding your concerns above, A 7” core will weigh a good deal more than the OE unit, personally that’s something I’ll trade off every time, but it’s a valid concern. I’ve held the ETS 5”, and while it is heavier, I’d doubt it would make a noticeable difference in the handling dynamics of your car. With regards to the lag, again a 5” will be virtually identical to the OE unit, and a well-made 7” core will only introduce a small amount of lag on throttle tip in. You guys get pretty nice catted downpipes OE, so your starting off with less lag than I’d perceive in my car. IMO a good FMIC is one of the best upgrades on the market for the N54, it’s not a “wow” product, but it relieves so much thermal stress from the system. N54 is an oven in terms of heat.
