I'm looking at my options too and I'm pretty set on the corsa system and borla is my second choice.

 

remember it is your choice and what system you want to put on is yours. its good that you have some options that you are interested in.

 

what happens if i delete the catalytic converter from my 2000 monte carlo ss?
will it sound good and beefier?

 

you will throw codes if you do the cat delete. if you have a pcm tune that deletes the second o2 sensor it will be a different story. but if you have a normal tune and delete the cat you will notice it sounding better but it will hamper perfomance. till you do a pcm tune to delete the second o2 sensor.

 

Code that would be thrown without a Cat is: P0420

 

If you're looking for a little bit better flow with better sound through a new exhaust system, Dynomax sells a catback exhaust system for $450 through www.3800performance.com and www.pfyc.com. Here is a clip of what this Dynomax sounds like on a 2003 Monte Carlo SS N/A 3.8.

Also, SLP sells the SLP Powerflo exhaust system, you can buy it on www.3800performance.com , www.pfyc.com , or www.slponline.com. It costs between $500 and $600 and comes with 3 inch exhaust tips. In my opinion this one delivers the best sound. Below is a clip of a 2005 Monte Carlo SS with the S/C 3.8, which sounds identical to the N/A 3.8 at rev.

Hope this helps!

 

Don't delete the cat for a sound change. The change is fairly minimal, and you'll be putting a lot more crap into the environment.

 

are you sure it would be a po420 cause mine threw the po140

 

If I remember right 0140 means no activity from the rear O2 sensor (ie you didn't plug it back in). 0420 is what you get if you leave the sensor in, but have a high flow- or no cat.

 

Does having this code reduce your car's performance in any way? Or is it just an annoying light you can't get rid of?
