Bigger single shot exhaust!!!

[BlackMetal]

I'm really surprised a vendor has not stepped up already now that 3.5" downpipes are more common. Last I heard RJC was working on 4" single which would be overkill for me but no updates from them lately anyway.

We will need a 4" cat as well...some of still have visual emissions equipment inspections.

Id like the 4 inch also.

The problem I have is: Where can I find a 3.5 cat that may be hollow that will fit up between the 3.5" DP and the cat-back flange? Would like for the cat to slip on to the dp don't want to weld it.

spun metallic substraight cats, shorty style, 100 cell cats, t-304 stainless > old style high flow oval type ceramic honeycomb centers cats

I buy my cats and resell them cut to size from http://www.fabspeed.com/ anyone want one let me know.

I run a metallic 100 cell. I also run a 3.5" DP. My 100 cell cat has been cut to a 3.5" entry and a 3.5" exist, goes into a y-pipe 3" into dual 3".
Haven't finished welding it all up yet, because I ran out of money

I don't think I even make enough money to look at that website.
Anyhow, I have the 3.5" DP and 2.5" exhaust.

How much for a 3.5" or a 4" cat for my ATR headers and dual 3" cat-back exhaust?
