Hey, I'm sorry to sound really stupid right now but I really need to know. I have a 6spd MT Acura TL 2004 A-Spec and currently have Comptech Catback exhaust (https://www.heeltoeauto.com/comptech...l-230-049.html) and was wondering if I was able to add a J-pipe, HFPC, and race pipe (https://www.heeltoeauto.com/combo-de...qpexhaust.html). I don't know if this counteracts the exhaust or adds to it but just wanted to make sure and really sorry if this is dumb but any help would be appreciated.

 

Yes they are compatible.
