What is the best bang for your buck performance modifications that you can get for the 300C?

My last two vehicles were trucks. I did everything to them, including performance chips, air intake kits, exhaust kits, and headers. I quickly learned what worked best, and what was a waste of money. Maybe there's already a topic here that has all these answers, but I couldn't find it.

I also poked around and found some discussions about performance modifications, but none of them (including mfg sites) had any dyno results.

To be honest, I'm happy with the sound of the HEMI so I'm really interested in getting more HP/torque out of it. It's not that I'm unimpressed with the power, either... it rocks... I just want to exploit it as much as possible!

TIA!

You can mod your stock intake for less than 10 bucks and get a good 10 hp from it.
Cut a hole in the front of the heat box and run a pipe firward to the grille, feeding it directly. You can use painted PVC pipe a dryer duct, whetever.
Ditch you stock suitcase from the exhaust. That thing is a big paperweight. Cost ya nothing if you do it yourself, maybe 40 bucks tops at any muffler shop. That'll score ya another 10hp.
Ouside of that, a real 360 air intake runs anywhere from 2-3 hundred bucks, good exhaust system 600 to a grand, jet chip is around 240ish, headers maybe 1,400 and the supercharger is upwards of 6k said n done.
twin turbos are on their way.

From the dyno results that were posted (near SRT-8 power and torque)

I'd easily have to say headers.

However, he did have a CAI and Borla cat back system also I believe. From what I've seen it's definitely worth the price of all 3.

As far as exhausts go the best dyno results have been earned by Borla (140112 and 140125) and Magnaflow. Intakes: Volant takes the cake. Headers are a viable option, but make sure the install doesn't require welding or any extensive fabrication.

Have fun, and let us know if you need anything.
