Resonators or Prochamber
Hi. Which would be better to get resonators welded to the over axle pipe or a prochamber welded to where my x pipe is? I'm looking to get a deeper and less drone. I am thinking of getting resonators like this

The resonator route would also be alot cheaper.

Thanks.

I don't think the prochamber will take away any drone, maybe minimal. I also don't think the resonators will make the exhaust any deeper, maybe quieter. I would just ditch the macs and find another muffler being as the macs are giving you the drone. May I suggest the prochamber and pypes mid muffler system

I'm running Hooker LT's , a o/r prochamber as well but with GTA mufflers. Nice deep sound and no drone.

MAC LT's, O/R Prochamber, GTA Mufflers. No drone, no trumpeting. Nice deep rumble at idle. Screams at WOT. Love it

I'm running Mac Prochamber w/high-flow cats, Pypes Violators, and stock manifolds. With no drone, or trumpeting. I've also noticed that my exhaust sounds both smoother, and deeper since upgrading to the high-flow catted Prochamber.

Thanks for the opinions guys. I think I'm just gonna stay with the x pipe for a while. The sound is growing on me.

Rocky, did you notice much volume increase with the Mac and high flow cats?

I actually tried each and both at the same time. Short answer is they will not eliminate the drone, just muffle it a little. You don't save too much with resonators because they have to be welded...unless you can do it yourself. Also, if you don't like them, it's a pain to find factory overaxle pipes, and the aftermarkets aren't 100% exact fit. I love my prochamber, but it didn't reduce drone, it deepened the tone of the drone. Your best bet is to go with GTAs or Corsas.

Scott, I did notice a volume increase, but not to the point where it's overbearing. The high-flow cats and Prochamber actually provide a slightly louder, but also smoother exhaust tone in which I no longer notice any drone.

I totally agree that an off road Prochamber will not eliminate drone, however since I've been running my Prochamber with high-flow cats. I haven't noticed any drone at all.

In short, the cats seem to work similar to resonators, and have apparantly made a significant difference.

As for the high-flow catted prochamber is concerned. Your correct, MAC took it off the market, thanks to the catalytic manufacturing co. refusing to honor they're warranty claims.

As a direct result, I was able to locate only 2 vendors who carried the last ones in stock over 6 months ago.

In the meantime, I'll post the websites of both vendors, and perhaps they just might have a couple of high-flow catted prochambers left in stock. Anyway, best of luck to you.
