Best Headers for 5.7

Hi guys - I have a 2014 RT and I want to add some headers to complement the corsa sport I added about a month back. Almost exclusively a street car but do like like to get on it when I find an open road. Also looking for a nice healthy rumble at idle. I suppose my first question is do I go with shorty’s or LT’s?

If you can go with longtubes (state inspections and crap) go that way. Shorties don’t give a great gain for the price and effort involved.
Unless you plan on doing major work down the line, stick with 1 3/4 or 1 7/8” sizes.
Two good brands: American racing headers and kooks
If you need a budget brand: jba (what I have on my Challenger but they didn’t make as much hp as the others will), still great sound though.

Thanks Frank. Do you know anything about the Corsa LT Headers? Just wondering if it might be better to stick with same brand as my catback to optimize the fit.

I really do not know too much, I only asked about Stainless Works because they sell complete systems, their redline set up sounds awesome, and they are located in Ohio (Same state as me). I like to support local people but I do hate paying sales tax on big ticket items.

I run SW headers and have no complaints. Their setup uses adapters between the mid pipes and cat-back. The mid pipes are 3" but the adapters can fit 2.5", 2.75" and 3" cat-backs. Every connection is slip fit (just like the OEM mid to cat-back connection) so there is no flange between the header collector and mid pipe (or cats). If you want air/water tight connections you do need to smear a little high temp silicone in the connections. They don't give you gaskets...just bolts and a tube of high temp silicone (run OEM gaskets instead). The bolts are holding up for me. I have run several hundred miles and bolts are still torqued down.

If you are getting long tubes, make sure you have a shop well an extra bung so you can run a wide band.

The only experience I have with SW is on my buddy’s camaro. They looked like decent pieces and were slightly cheaper than the other big brands but they had some clearance issues.
We had to bang in one of the tubes a bit to clear the steering column and after both sides were on, they didn’t mate up great to the stock exhaust. Beyond that they were great on his application. He picked up about 15hp across the rpms when he had it dynoed.

Yeah, but on the pre-2017 challengers the 5.7 have a smaller cat-back pipe diameter...so some modification of the 6.4 mid pipes is required.

yeah JBA Cat4ward Headers might be a better choice, if you don't want long tubes.
