Im looking at getting Weapon r or k&n witch one do you thinks better over all???

But back to the topic... does any one have eather of the products with the stock exhaust?
how does it sound?
And finally what exhaust is the best out?

Price is not a factor list what you think power and hp wise

 

Well. if you are gonna get intake you gotta get exhaust. Injen is what i recommend. If yah get a larger intake of gasses. but its still going out a stock pipe. You wont get the power gains the intake is capable of. I heard Magnaflow was comming out with a catback for the tC. but I have not seen any actual adds. Borla is also a good buy. but they only have axle back as far as i know for the tC

 

no weapon R intake.
just not a good buy.
look around more on the CAI.
i dont know much about the DC headers.
upgrade the exhaust. catback would be best
i know tctunerz has some but i dont know how they are with their products
