Am I on the right path?
What I have.
5.4 auto 2wd extended cab completely stock except y-pipe was installed by previous owner with 156K miles
3.73 rear end
stock wheels and tires 265/75/16
What I think I need/want to do.
Add custom 5 star tuner
Add performance muffler. Would a complete Cat back give it much more power to justify the cost difference?
Go to 4.11 gears in the rear end. I drive on the expressway a lot, will 4.10 be to much? I'm at 2000 rpm at 70 now.
I'm up in the air about a CAI. I've read several times on here that the factory intake flows almost as much as a CAI but looking at the 5 Star tuning site they have a one that flows 26% more than stock.
Am I headed in the right direction? What say you? Thanks in advance!
the ypipe saved you some money. the cat back system eh unless you are wanting to do a custom true dual exhaust not really going to benefit from a cat back system personal preference i would just cut off stock muffler and find you a muffler with the sound you want. anything aftermarket is going to flow better than the stock muffler. 5 star tune from what i have read on here every one loves them can not go wrong with them if i had the extra funds i would be inclined to get one. the gears go with 4.30 i have 4.10s and do not hate them but would like something like the 4.30s for better towing at freeway speeds
