Yea I deleted the resonator the first time through and replaced it with x pipe. Prolly just have the cats removed and see what the 10 series sound like, like you suggested and go from there. What's disabling the rear O2 sensors gonna do for me. I'm still kinda new to all this lol

 

the rear o2 sensors are there to monitor the cats and make sure that they are working, when you remove the cats it will notice and generate a code and turn on your engine light. so the tune ignores that.

 

So after some phone calls, turns out the cats are near impossible to remove. So o have to get new headers. My question is, I'm seeing headers ranging from $500-$1500, I don't really know what I'm lookin at lol. I don't wanna go stupid cheap, but I don't wanna get shafted if the $500 ones will be just as good.

 

just looked at the 15 exhaust, yeah looks like the left side cat is intergral to the manifold (most likely to slow modders), so you will need headers for sure like you said. if i had a 15 and was going to delete the cats i would go with these from pypes. i have a pypes system on my 03 and is good quality and stainless at a decent price. http://www.americanmuscle.com/pypes-...in-1516gt.html

if you decide to order them or anything from american muscle, make sure you contact the rep on this forum to get your discount code, i think you have to have 50 posts but it saves you some coin

 

You wouldn't happen to know the discount % would you? Just signed up for the autoanything.com newsletter and I get 20% off my next purchase.

 

i cant remember off hand, thought 10% maybe. sounds like you have a good deal @ 20% as long as the initial price isnt higher

 

Found another lope tune too by ford. Looks like they done it for 2014 models with the track key. Does anyone know if this is available for 15? From what I've read it won't run rich and melt the cats. Would be nice to achieve my goa without all the extra expense.

 

Just realized you referenced this particular tune in a previous post lol. My bad
