MAC O/R vs Catted Prochamber with Borla Stingers?

[Jdb03shadow]

Just installed the borla stingers on my 03 cobra, thinking about the MAC prochamber offroad or catted. Is anyone running these? Does the catted prochamber sound much different from the stock h? Let me know if you have advice, are running these, or have heard them thanks!

I have not ever had MAC prochamber, but if I did I would go offroad, I've heard them, I get hard every time. Borla stingers are the best.

I didn't think you could get a catted Prochamber anymore. But either way, the Pro offers a deeper sound than the other options out there. An X gives a little more rasp catted and a lot more in O/R form. A Pro tends to a smooth out any rasp and deepen the tone.

Prochamber and stingers are probably the best choices for exhaust on these cars!

I bought mine with MAC LT's, catted prochamber and Stingers, after 2 weeks, ditch the cats and installed a O/R Prochamber, it's now much louder and raspyer around 2500RPM when you apply enough load.

But again, LT make quiet a difference on sound.
