I want my exhaust louder! But I dont wanna have to buy a new muffler or exhaust setup. If I gut my cats, will my truck run like ***?? I have Edit so I can kill the rear O2's. Is it better to cut out the cats and weld in sleeves? Thanks in advance!

 

I just gutted mine and it is louder. Given your mods ... I would say go for it. I actually gutted mine out though, no welding in pipes through them, just hollow them out, weld them back in place and go on about my way.

I will say this ***WEAR EYE PROTECTION!!!!***

I got some **** in my eye and had to have it dug out while I was doing the actual gutting. It is not fun getting metal flakes dug out of your eye with a dentist pick and a 'polishing wheel' (looks like a dremel with a ball point engraving bit).

I can hear the cam lope a little better with the cats gutted too.

Did I mention you should wear eye protection? Just being careful not getting it around your eyes won't help, the **** is dusty and flies everywhere. A mask would be nice too, but at the very least were eye protection.

 

It's gonna sound diff for sure, deeper and with some potential for rasp too.

Ah yes, getting **** in your eye is bad. Anytime I am on my back under a vehicle or cutting/grinding I gots the glasses on. I've had rust, oil, coolant, and such in my eye and that burns or cuts and HURTS like a *****!

 

I got rid of mine and its definately a lot louder. Lots more rasp as well.

 

I cut off my muffler and have a single three inch pipe y'ed under the cab to 2.5" pipe with Corsa tips tucked under the bed near the rear. Sounds great but kind of has a little rasp to it. Any way to get that rasp to go away?

 

Put some mufflers on it

 

Before I gutted the cats I would get like a whoosh sound when I would wind it up. I think what it was is the exhaust being filled up to the max with the blower. Now that the cats are gutted, it does sound more like a motor rather than a jet engine. It does have more rasp to it as well.

I was never under the truck in a position to have **** fall on my, that's what's so bad about my eye happeneing this time. I think what it was from is actually gutting them out. **** flies EVERYWHERE.

 

I didn't find it very easy to gut mine. I took a 2 " pipe and a sledge hammer and busted it through. Seemed to take forever. I had the y-pipe clamped to a vice on my bench. Than I cleaned it up with a flat bar. Vacuumed all the crap out and stuck a wire bruch on a drill to clean up the residue stuck to the walls.

This was all easily seen because of the Az header flanges.
I think it helped the sound with the BBtriflo.
Go for it.

 

Idid something like that. I started with a paddle drill bit, the biggest/longest one I could find. I wallered out as much as I could with that, then got a small pipe and started beating around with it. I ended up taking the small pipe and putting the converters over it, finding something hard to hit it on. I would hold the pipe in the converter, pipe down, converter on top of it, and slam the converter down on top of it, making the pipe hit somehting hard. It worked well for me.

Did I mention though ... WEAR EYE PROTECTION

Last time I gutted my converters I got **** in my eye them too, but that was from me and a sawzall under the truck cutting.

 

haha.... try getting some jet fuel in your eye, while half of ******* afghanistan is blowing in your face... oh that is FUN!
