Hi,

Was considering modifying the remainder of my exhaust. I currently have BBK Shortys and Flowmaster American Thunders on my 2014 GT. I was considering swapping out the stock H pipe and the stock over axle pipes. The only thing I cant touch are the cats because I live in New York. My question is, how restrictive are these stock components and is it work it to swap these out? I see heartthrob sells a kit. heartthrob-hpipe-1112gt.html

I am better off having an exhaust shop make me a custom set up? Cheaper or more expensive? Thanks!
