Ok, well went Christmas shopping today and got stuck in the middle of the intersection because of stupid drivers/car accidents. So, I had to WOT to hurry and get out of the intersection and into another lane to prevent another accident. After doing this a sure could smell the cats. woooo weeeeee was it bad. I'm going to hook a mastertech to it and check lean/rich condition of the rear 02's. Anyway's if my converter comes out bad.-"The rotten egg smell was horindous" I don't really think I'm going to replace it. I checked a few places and found a universal one for $80.00---BLAH- I hate customizing crap to make it fix...... And stock replacement is Front $565.25
Rear . 208003Y225 $667.31---through Nissan according to alldata. I have no cats on my Mustang, and my buddy cut his off his aurora. Anyway's my question is if they turn out bad and instead of replacing I put a straight pipe (Or mandrel bent) in place of it does that change the sound of the exhaust. He cut his off and it gave his car a much loader throatier sound, which I don't want on my family sedan.

 

I have the HighFlow Cat from Custom Maxima and it works well. It changed the tone on MY exhaust, I am not stock at all though. Plus its only like $150.

 

I like it being very quite, its perfect stock-Just the way I like it. My loud and obnoxious car is away for the winter, I consider this to be my "luxury" daily driver and want to keep the tone/DB level right where it is. Wasn't sure if that was possible if cats where cut. - I haven't verified the cats are bad yet, but am assuming they are. BTW no emissions testing here.

 

if you want to go somewhat legal but better flowing, you could always go with a random technologies high flow cat.

 

I would stick with a HF Cat, it will barely change your exhaust tone on a stock car. Gutting it or deleting it will effect it more.

 

thanks guys - guess I'll take a look at those two places. Good info.
