Guys does anyone out there just run straight cats and no muffler? Any sound clips? What about resonance? Thanks. <img border="0" title="" alt="[Razz]" src="gr_images/icons/tongue.gif" />

 

i'm running straight cats but they are 3 in magnaflow cats with three inch all the way back with an x pipe true duals i love the way it sounds but it is loud and resonance isnt as bad as the stock y pipe and cats only

I unbolted the exhaust at the flang at first it was a bit loud, then I cut off the two foot length of pipe (from flang to the muffler with the first hanger retained) off the old exhaust and bolted it back up. The langth of pipe did a lot to shut it up and move the noise away (the tone was the same). I get lots of complements from others and it gave a nice, noticeable increas in power and gas millage. I call it the 'free exhaust mod'

Gunner: if you want to know what it sounds like just unbolt, move it out of the way, and it and fire it up. If you like it keep it, if you don't bolt it back up, no harm no foul.

 

Gunner: By the way, welcome to the board. I just noticed it was your first post.

 

I run cats only. It is pretty loud at first but, you will get used to it. With my old 5.3 I shifted at 6,250rpm and it really woke it up with no backpressure.

 

Thanks guys, I'll have to give it a try. I'm on a tight budget and cant afford and exhaust and stuff.

 

yeah thats what i'm talking about the free exhaust mod i bought a gibson cat back and when i had it off at the flange i fired up for fun i liked it so much i didnt care about the gibson anymore cuz i loved the sound of the cats only
