So I got the Magnaflow, dual exhaust put on today. It sounds great, not over-loud in the cabin, but enough to know its not stock!!

Ty

did you put in high flow cats, or did you leave the stockers in?

Left the stockers in. How much is that? Does it make a huge diff?

some pics would be awesome although i cant talk since i suck at resizing photos

Ty

when you use photobucket, it will automatically make most pictures smaller, and then you can choose to make the immage 75%, 50%, or 25% the size of the original immage

On the hi-flow cats, I am not sure as to how much HP gains you would havem but I know some of our 04-07 trucks have 4 cats and lots of the owners take 2 out... I personally would not spend the extra dough on the hi-flows as they wouldn't be to noticable on the "butt-o-meter"...

ford trucks 97-up have 4 cats, and some people do cut out the two pre cats, but they then have problems with their CEL being on all the time.

most people usuallt replace the pre cats and the cats with two high flow cats. there WILL be a high drop in back preasure, so people who run high flow cats, a larger diameter pipe, and no muffelers or glasspacks dont notice a performance increase, and usually a drop in lo end power.

running high flow cats is mostly to get more sound.

which would give you the greatest hp or performance gains
1 running straight pipes from the stock cats back no muffler or

2 running straight pipes with h-flow cats no muffler
