misterp Posted January 20, 2010 Report Share Posted January 20, 2010 ???? You are using ARH headers with the factory cats??? Or are you saying you want to gut the ARH-provided cats? Mr. P. Quote Link to comment Share on other sites More sharing options...
SSplaytoy Posted January 20, 2010 Report Share Posted January 20, 2010 The sound will get louder if you gut them. Better or worse is more of an opinion. One way is to take a drill with a long bit and start drilling holes into the screen and crap inside the cats to help break it all down and then take a small pipe or prybar(something long enough to poke down in there) and start breaking it up more and pulling/pushing the crap out.

alex.t Posted January 21, 2010 Report Share Posted January 21, 2010 if you gut your cats with the exhaust you have its going to be loud and raspy . Quote Link to comment Share on other sites More sharing options...
zachm89 Posted January 21, 2010 Report Share Posted January 21, 2010 (edited) im going to gut my stock cats this weekend and cut enough off the ends to slip in a section of 2.5" pipe, then just weld that all the way around so its nice and clean and still looks stock, that way the exhaust doesnt have to go through a big hollow chamber. ill take pics along the way if it will help any Edited January 21, 2010 by zachm89 (see edit history) Quote Link to comment Share on other sites More sharing options...

dirttoo Posted January 21, 2010 Report Share Posted January 21, 2010 if you gut your cats with the exhaust you have its going to be loud and raspy . Pics would be great.

kcsilveradoss Posted January 21, 2010 Report Share Posted January 21, 2010 i wouldnt personally gut a set of highflow cats unless the went bad Quote Link to comment Share on other sites More sharing options...
Fireman31 Posted January 21, 2010 Report Share Posted January 21, 2010 Get a long flathead screwdriver and a hammer, use the screwdriver like an ice pick and chisel away at the internals.....whala! You now have gutted cats......... Quote Link to comment Share on other sites More sharing options...
tburkdoll Posted January 22, 2010 Report Share Posted January 22, 2010 Don't gut them unless you want a tinny sound to your exhaust (IMO of coarse)... get hi flows or just weld in a straight piece. Quote Link to comment Share on other sites More sharing options...
ss454327 Posted January 22, 2010 Report Share Posted January 22, 2010 (edited) Why gut them when you can probably sell them and have a shop weld in a piece of strait pipe. I bought the system from ARH with no cats and it's actually not raspy or loud the way I have it ran (dual 3" Y'd into single 4"). I'm running a 4" Hooker Maxflow muffler and I dumped it 12" past the muffler and it's deep and quiet until I go WOT. There is a video of one of my runs in the strip section.

misterp Posted January 22, 2010 Report Share Posted January 22, 2010 I want to gut the cats ARH provided DON'T! Sell them!!! You can get a couple hundred bucks for them. Mr. P. Quote Link to comment Share on other sites More sharing options...

joeyg Posted February 16, 2010 Report Share Posted February 16, 2010 What did you end up doing? I had one plugging and hollowed both and regret it. With the Flowmaster, the drone and sound level is LOUD. I'm actually planning on getting some high flows and putting them in. BTW, I used a crowbar and compressed air to ensure I got all the stuffing out. Quote Link to comment Share on other sites More sharing options...
