RE: CATS or NO CATS?
Personally, I like cats. Those little furry things r fun to play with. I got one but when I play with him too much he claws my hand bad. He's fun though and meows a lot. I think u should get some cats. Cats over no cats ftw!

Scroll down to "Headers -- Primary Pipe Diameters"
"Big pipes flow more, so is bigger better? Answer: absolutely not." Same goes for the cats/no cats argument I would think - there is an optimal level of exhaust flow...too much flow = no scavenging, too little = too much back pressure and decreased performance. Taking the cats off would be too much flow for a non - f/i V6, at least that's how I see it.

RE: CATS or NO CATS?
thats right.....backpressure is bad but some will exist nonetheless. i'm agreeeing about the point that there is an optimal level of exhaust flow: close to zero backpressure and maximum exit exhaust velocity. how does backpressure create scavenging when its bringing exhaust gas back to the cylinder? only good thing that could do is bring fresh air/fuel back into the cylinder during the valve overalap but that would also bring exhuast gases back in and contaminate. i'm sure all these negative things will happen at some degree but keeping them to a minimum will result in better effeciency.

Did you do the interior yourself? It looks beautiful!

As far as this debate....I think I will just go with some universal high flow cats and the slp.

haha....yeah, i'm done with it. anybody can research it and figure it out like i have. makes sense one you understand the whole backpressure concept. i see that pypes sells some high flow cats. anybody have em?

Sorry, but if you have a V6, you'll never get the "growl"...at least, I've never heard a V6 growl...

Yea my friend got pulled over a month back and the cop was a complete jerk.. gave him a speeding ticket... bent over and looked under the car (no cats). wrote him a huge ticket. not worth it IMO.
