When I first took a look at the cats on my new set of AR LT header H-pipe, I though 2 things.

1) Man, that sure looks familiar. I took something like that out of my intake tube when I first got my 05 Mustang (anyone remember the HC trap?).

2) That sure looks like it will restrict air flow.



Then I saw the inside of the stock cat:



Oh YEAH! The ARH cats will flow better!!

 

They will indeed flow better, but not as well as no cats

 

Could we see those pictures again? They didn't post.

I'm still deciding on my exhaust, as I definitely don't want to ruin the low end torque numbers and sometimes eliminating backpressure too much does that to N/A [normally aspirated] engines.

Sorry Mike, they come up fine for me. Don't know what I can do to help you. They are hosted on photobucket.

 

They show up fine here.

 

yeah I just put on my bassani X with hiflos, and it basically just looks like a honeycomb resonator inside of the cat!

Jim- BTW do you know a guy around the neighborhood with a grabber orange GT, white stripes, white cdc front chin spoiler? Him and a couple guys stopped over to check out how the install was goin last night, and I thought they were pretty cool. They said they visted CTS a bit as well.

 

Yeah, I know them, the live right behind me. One guy was white stripes on his GO, and his next door neighbor has black stripes on his GO.

 

My setup doesn't seem to lose anything down low verse stock but no dyno numbers yet to prove just going by feel, especially since the cai/tune are added and the car is much more powerful
