agreed. the headers will def make some HP, the first step would be ECU cause its more bang for the buck. Any ECU upgrade should be able to benefit from headers, stock ECU as well. How many ponies I dont know, only the dyno can tell u

I would do headers first or do both at the same time, that way during your tune you can get any codes that were thrown erased. or if you go to a reliable tuning place with a dyno you can get a custom tuned designed for your mods.

Ya maybe ill wait for the ecu and headers next summer?
Unless I get ECU in august and ask if the guy will reflash for free? which im pretty sure he said he would. SO maybe get a reflash after i get headers
You think itll be too loud though?
Cause OP left he factory mufflers on, and those drown out the sound a lot

one of his other videos with the headers is when he had a muffler delete so watch that and just remember that it will be quieter than that.

jealous. friend of mine did a muff and xpipe delete like me except the droning in his cabin is probably 30% of my drone (before i threw back on my mufflers). If this is silent when cruising then its purrrrrfect
