I mean yeah you can it won't hurt anything just jet it properly is all. My question is are you planning on Modding the motor a lot more? In my opinion if you don't have any plans to do anything like porting, cam, FCR carb upgrade and higher compression I personally wouldn't spend so much on a High Dollar exhaust system like that if you're just looking for a little better exhuast and some good noise you could go with like a HMF, Big Gun etc. The only reason I say this is just because (in my opinion) the Dasa, Empire, Monster etc they're good for when you have semi biult engine that NEEDS to breath and then yes it's absolutly neccisary to spend the 600.00 on a good exhuast like that. Like I said I am not by any means saying "No Don't buy it" I'm just explaining that on a stock motor it won't make a Huge differnce (if that is what you're hoping for) probably not noticiable is all for the price that they are.
