Hey Guys I'm starting out with an exhaust as my first mod for my car. I'm getting a 2.5'' stainless mac kit. What do you guys think would be better a Mac pro chamber or bbk off road X pipe????????? Let me know what you guys think. Thanks

eleanorsvtcobra said:this is prolly a stupid question but whats the difference between the mac h-pipe and the mac prochamber? they both look the same from what i can see. both 2.5" and coated, same design.
