3.5 mods open to suggestion

Hi
You may want to consider a Catch Can. It will not improve your HP but it will keep your engine cleaner on the inside. Kind of a budget mod, price around $50 - $150, depending on the brand of choise.

Just to be clear, if you have a 3.5L you don't have a Pentastar. The Pentastar was introduced in 2011 and is 3.6L.

I have a 3.5L and without changing from single to dual exhaust and a CAI (both of which will boost your HP a little but not much), your only performance mod would be a tuner. But then your spending $340+.

I searched around and found a R/T dual exhaust that I bought for $75 (only had 7500 miles on it) and had it installed for $125. Great looks and sound, plus a tick up in HP. You can get a CAI for under $200, if you don't go for a CAI box and not a CAI with the air intake tube.

Without spending some $$$, stick with cosmetic mods. I put functioning hood scoops on mine ($55 from the dealer), hood struts (about the same), and 3.5L hood scoop badges ($35 from the dealer) .

If you look around you can probably find a CAI for less than $200.

I have a 2010 SE with the rally package. I love the car. I first added a K&N cold air kit then last summer a Borla true dual exhaust. There is noticeable mid range power gains from these two mods. The Borla was pretty loud for a few months until it seemed to wear in. Looks great with the two sets of dual tips. I bought a RT rear valance on Ebay for it. Easy install of the valance. I had a Midas install the exhaust. They did nice work. Last mod will be a tune for it.
