I think what teamrx8 means is that the davesport cat is not recommended for FI or heavy use as it is quite weak.

Even Charles has since updated that it is not recommended for FI cars.

I had a davesport cat that blew outta my car when on the dyno.

 

where was it mounted? that could be some of it, or i wonder if after they got noticed they cheaped out for the money. to bad if they did..

beers

 

I think it was supplied with a well know forum vendor's midpipe

for a competition car it is too small any way
