I know I said I didn't plan to mod, but have been considering the Mopar CAI and catback system. You guys corrupt the hell out of us bone stock guys. :D

The dealer has them for $307 and $1148 respectively. I have no idea how much labor would be, but I do know neither will void the warranty as I've already asked. I see the catback claims 50 state emission compliance, so I assume Colorado inspectors won't get their panties in a wad. Anyone know for sure?

From reading this site I know there are better performing components out there, maybe even cheaper. But one, I don't want much if any louder exhaust. Don't care about the intake, but many claim the Mopar sounds killer. Two, I don't want any warranty or service issues. From what I understand, the computer will auto adjust to the new components over some period of time. So I won't need a tune right away, if ever.

I guess my main curiosities are what kind of increase in performance can I expect with just these two changes? And how much louder the catback is? If it's just 5hp or something like that it's not really worth it. If it's like 20+hp it's more justifiable. Anyone dyno'd the difference between stock and these two components? If it's already been posted, my apologies, but I did search and read a boatload of posts to find the answer.

Any help or suggestions are appreciated, but I'm not into super loud, tunes at this time, or superchargers. It's just my DD / toy that might get some Xmas presents. ;)

Thanks!

The mopar intake is worth maybe 4-5hp max at most...The corosa catback system 10-12hp

Thanks Mr Freeze! Not as much as I was hoping for considering the cost... :(

I guess I'll have to query the dealer as to what they allow. I only asked specifically about these mods. He said if it's Mopar parts, no problem. Anything else and it depends. He did say they were having a performance shop do some mods for another SRT8 customer. So maybe their warranty policy depends on whether they get a cut or not... Well I've got to take it in anyways. My check engine light and the gascap message have been there since the day after I picked it up. He said wait and see if it resets. It hasn't...

The exhaust is more sound than performance. If you're considering doing more extreme mods, it may help more but not as much as you were hoping.

The CAI with a Predator tune will help more and it's cheaper. If you're looking to extract performance, you need the Predator. There's no way around that. The CAI will help get more air in hence more potential to develop more HP.
