I know some people were contemplating a car delete, but wanted to know how it sounded. Well here you go. It is a 22 second video of revving to get an Idea of the sound and a burnout/take off. I hope it helps. http://videos.streetfire.net/player....B-11552C0F0A17  |  |  | | 08-18-2005, 03:55 PM | #2 | | Senior Member Join Date: Dec 2004 Location: Muncie, Indiana Posts: 1,551 |

I think I'm glad I kept my cat. The sound reminds me of my friends GSR with no cat.

I don't think it's the deleted cat that makes it so loud, but the exhaust itself. I'm sure it's a straight through system with no resonator.

Cheers, | The cat was replaced with a custom bent pipe. There is a resonator after the cat that was already there. The muffler also was loud and had an aggressive tone before the cat delete. I think it sounds like a race exhaust. I also think it sounds a little like a straight piped v-8. Especially in the way the tone changes from on to off throttle. For some reason at cruising speed the exhaust quiets down and does not resonate like it did when the cat was on. | | | | | 08-30-2005, 07:52 AM | #9 | | Senior Member Join Date: Jun 2003 Location: San Jose, CA, USA Posts: 253 |
Yeah, removing the cat seems to lead to that metallic-ness. Otherwise, it's all good.  __________________ Andy Chittum - Mad Man Motorsports | | | | | 09-14-2005, 05:13 AM | #10 | | Senior Member Join Date: May 2004 Posts: 411 |

My 00' s10 resonated like a rice burner on steroids with a 40 series and cat delete....andy's car times 2 maybe...but the most fun thing was to wind a gear out, ease off, and pump the gas pedal....can you say fireball  I am scared since his car is louder than my 4.3L s10, it still has it's cat, but also has a 40 series flowmaster. I think his car resonated worse before the cat came off though, at least inside of it. Andrew BTW, we scared all the birds away from the BSU parking garage!!!!! And the Vortec engine does have a really mean tone to it!!!! | | | | | 10-21-2005, 04:07 AM | #12 | | Senior Member Join Date: Dec 2004 Location: Muncie, Indiana Posts: 1,551 |

How much of a power gain should you expect? | | | | | 10-21-2005, 04:20 AM | #14 | | Senior Member Join Date: Dec 2004 Location: Muncie, Indiana Posts: 1,551 |
I couldn't quote power numer exactly because I haven't dynoed it. I did notice a quicker smoother rev through 7k and it had more power espceially up top. So the butt dyno sensed more power. | | | | | 10-21-2005, 04:22 AM | #15 | | Senior Member Join Date: Dec 2004 Location: Muncie, Indiana Posts: 1,551 |
I guess I could say I noticed as much or more difference with the cat delete, than the performance chip. | | | | | |
