Should be compatible with the stock exhaust correct? And I plan on the ARK Grip or MD tdx2 exhaust so that'll all be compatible, and not a waste of money?

 

Yes with the stock. If you go with the MD exhaust you won't use the resonator, with the ARK you will.

 

So should I just get the straight pipe or the HFC? I'm assuming HFC will sound a little better?

 

Only you can decide. The straight pipe will be louder, the resonated will be a little quieter as will the HFC pipe. The HFC should help you pass emissions also.

 

I ended up just getting a whole exhaust system instead cause I got a good price on a BNIB one. Since I have the aftermarket exhaust system now, will the XYZ pipe still be compatible/beneficial? And the ART pipes will still be compatible correct? Thanks for all the help blue dream
