I have a Pacesetter header and I want a Corsa Touring cat-back. What are my options for downpipes with a high-flow cat???

 

options as in brands or size of dp??

 

Both would be nice to know I suppose but I had brand in mind w/the op. I wasn't sure if they would all bolt up without cutting.

 

I'll sell you mine it's a 2.5 down pipe with no CAT but all you have to do is buy a high flow for like 50 then take the downpipe to a shop and pay 20 bucks for them to weld it in! If it's emmisions youre worried about I did just fine? I'm asking $130 shipped.
