I currently have the MAC A/B's and like how they sound but I'm looking to change it up a bit. What would go better to go along with the MAC A/B's either the Pypes X Pipe with Pypes high flow cats or the MAC Prochamber with Pypes high flow cats?

Prochamber with no cats This setup sounds AWESOME....My o/r prochamber was sent today and will be on in a couple weeks. Prochamber FTW

I was thinking about the O/R Prochamber because I don't need to get inspected for 4 more years. Any other O/R owners from Cali have any trouble with their O/R setups and getting pulled over?

I ran O/R prochambers for about a month and didn't get pulled over, but the car will make the unburnt fuel smell, so riding next to or infront of a cop especially a motor cop can be a little nerve racking. I decided to add magnaflow hi-flow cats. Well worth it. It cleaned up the sound. Made sound less raspy inside and gave it a deeper tone. Prochambers with hi-flows FTMFW.

I was kind of concerned about the unburnt fuel smell especially since I work near the Torrance Police Dept. and the mustang is my DD. How hard was it to add the hi flow cats to the prochamber?

should be easy to do. I thought about doing the same when I finally get the rear section of the exhaust how I want it. But plenty of room, just cut and weld.

I had a shop near San Diego install the cats. Like Laker stated, there is plenty of room for the cats. I paid around $320 parts and labor for the cats install.

How much did the Magnaflow cats cost snd where did you purchase them from?

gman73

The cats were $225 for the pair. I purchased them from Lastcallracing.com. It's a mustang performance retail shop out of San Diego.
