Headers

I want to buy headers for my 2015 R/T Shaker Plus. I would appreciate some recommendations. I want to increase power in the car.I don't want to spend more than $1500 or so on them. And if I were to upgrade to new headers would it be a complete waste not to buy a new exhaust?

Do what you want now and if you will regret it in the morning sleep in late!

Long tubes will require a tune which will basically void your power train warranty. Are you okay with that?

With that budget you can get top of line... I recommend American Racing or TTI.. With Mid pipes you may go just a little over 1500 but not much.

As for the exhaust no need to upgrade to support the headers. The factory exhaust is a straight through design, no restrictions. You could gain some top end going from the 2.5inch up to 2.75 or 3inch exhaust but if you're not making any other changes to the engine the benefit wouldn't be worth the $$$ IMO.

I wouldn't even worry about getting a new exhaust. I just did my headers and it's the only modification to my car. The car feels like a completely different animal now, it's actually pretty crazy! Your stock exhaust is fine, guys aren't really seeing much for improvements in ET's and HP with catbacks. Nice thing is doing headers makes your car sound just awesome even with the stock exhaust. I went with stainless works headers and catted mids. It was $1600 USD. I ended up getting a hemifever tune for $160 after the install. It was 100% worth it. I made a comment that if I would've known what my car would be like after installing the long tubes when I bought my car I would've got them years ago!

Luke, just a couple questions, would swapping out the exhaust from an R/T to a factory SRT set up hurt the warranty? Would swapping the factory cat back system from a 2018 R/T (Automatic) to a 2015 R/T Automatic hurt the warranty? (I know I would have to delete the active valves). Is the 2018 oem exhaust available? Cost of an oem cat back?
Thanks

Remember, on +2015's getting a tune requires an unlocked PCM so it's going to cost more compared to a pre-2015 model. If you wait a couple of months a lot of vendors will have some good sale prices. I bought my SW catted headers for 20% off with free shipping.

anything forward of the mid pipes, including the mid pipes has the potential for restricting the warranty, anything behind the cats, does not, cold air intakes are fine as long as they are dry media, no oiled filters

I am sure some dealerships will restrict the warranty if a cat back system is installed on car equipped with active exhaust, no?
