[email protected] Posted November 25, 2008 Report Share Posted November 25, 2008 I am in the market for some hi-flow/aftermarket cats. Should I just buy new stock ones? Just wanted to know what everyone has, what they like aobut em, what they dislike about them, etc.... I could not find a good thread in the search, so I just started a new one! my mods are in my sig if you need an idea of what I am working with as far as bolt on stuff. No I dont live in Cali nor do I plan on going there anytime soon with my vehicle, just done want to kill the person behind me with carbon monoxide poisoning! Thanks for looking!

kersey Posted November 25, 2008 Report Share Posted November 25, 2008 I am running the dynatech CATS that came with the headers. They seem to run fine, will be getting rid of them as soon as i get the money to redo my exhaust. I am planning on running no CATS and dual super 44's flows.

It past 2 vehical inspections though, one by the dmv and one by a state patrol. i was looking at those, but really dont like the fumes that come out of them. A lot of my import buds dont run cats and that shit gets annoying. Most of all I hate the smell, one of the reasons I stopped going on cruises...... Got tired of going home with a headache or feeling dizzy! Quote Link to comment Share on other sites More sharing options...

firervfd37 Posted November 26, 2008 Report Share Posted November 26, 2008 <---Once again knows nothing about this stuff. Do diff. Cats give more HP? I need a semi cheap way for more HP. Would love to S/C or Turbo but no money for that right now. Any ideas? Quote Link to comment Share on other sites More sharing options...

Got tired of going home with a headache or feeling dizzy! add a gallon of 110 to every tank and it will smell like a million bucks. but i guess the only time i smell the "no cats smell" is when i walk around the truck or only if the wind pushes it back to me at a stop light. Never smell it driving Quote Link to comment Share on other sites More sharing options...
BigCountry Posted November 27, 2008 Report Share Posted November 27, 2008 I miss that smell myself. Cant wait to get rid of the cats. Quote Link to comment Share on other sites More sharing options...
[email protected] Posted November 30, 2008 Author Report Share Posted November 30, 2008 ended up purchasing a pair of 3"x11" magnaflow universal 300 cell density metallic, will most likely put them in place of the resonaters that come with the magnaflow 15838..

shadowsniper3006 Posted November 30, 2008 Report Share Posted November 30, 2008 what does 300 cell density mean? are there better and worse cats to get based on this number Quote Link to comment Share on other sites More sharing options...
Jond983 Posted November 30, 2008 Report Share Posted November 30, 2008 honestly u don't need aftermarket cats..the stocks ones flow well enough. but i'd keep your stock cats and just hollow them out. and get it tuned for the rear O2 sensor delete. although aftermarket cats will make your exhaust sound a lil deeper. i was running dynatechs took em off and installed an off road y pipe and i absolutely LOVE the sound.
