Does anyone make stroker kits for your 3.7? That might be a good way to go if you want more power and to keep it n/a. A port/polish and a valve job would help a lot, too, but it's too bad no one makes cams for it. Without cams, a valve job is almost moot. 😞

A turbo or supercharger would probably be the best way to get more power out of it, though. I'd recommend a supercharger: better response off the line, fewer modifications. With a turbo, you'd have to install an up-pipe and down-pipe to the existing system.

I could do a high compression motor if I wanted and get near 300 rwhp. But I found the internals nessecary to run boost. I also can adapt the wranger turbo kit to it rather easily. And while no one makes cams I can have a custom cam grind done. But honestly the stock cams are plenty aggressive as it is now.

Believe me, everything everyone has suggested I've already looked into. I've become sort of the go to guy for 3.7 performance.

The only thing holding me back honestly at this point is tuning. The only people that have anything is Hypertec for the 2008 to 2011 3.7. If sct has support for it I'd already have custom tuning done.

Doesn't Diablosport make a tuner for your engine? Their Trinity and Intune i1000 are pretty versatile. I haven't heard a lot of good things about Hypertec, unfortunately, but that's all been from several forums.

On the topic of exhaust, I'm considering the OBX headers for 6.1 Chargers and whatnot. I'm leery of grinding the tranny bell housing, and Kooks are about twice as much as the OBX.
Anyone know of some fairly inexpensive high-flow cats?

What ever fits your budget. The things i want i am going have to save. Obx are around about 700 to 800. Kooks are 1200 to 1700 depending on what u do to them.

I figured you had. Sucks that there isn't much in the way of kits you can do, but custom jobs are more fun, right?

Yeah, I've been looking into building my own exhaust using clamps and paste to piece it together, since I have very little welding experience. The midpipes are going to be challenging, esp since I think I'll have to route both pipes down the passenger side; I've heard there's a lot of wiring under the driver's side, and I'd rather not melt it, lol.

Well it's not that there's wiring under the drivers side it's that is where the fuel tank is.

A fella in this forum (Sleeps, I think his name is) said that there was a bunch of wiring routed under the driver's side, so that's what I was going on. I haven't had a good look at it, as I don't have a lift or even a level, sheltered parking spot.
Has anyone heard anything good or bad about using exhaust paste combined with clamps in a diy system? I know all the hangars and the fitting will be a massive pain in the arse, but if I can save a few hundred dollars and still have a solid setup, I'll do it myself.
