Mac's with stock CATS?

Mac's with stock CATS? I've been thinking about getting a set of headers, but want to keep the CATS for emissions. So would I still see a pretty decent gain with the MAC mid-length headers and the stock cats? Can't go with long tubes because I'm running sportlines and I already have a 3200 Vig installed

Re: Mac's with stock CATS? There is not an easy way to do that.... and the mac cats suck hard. I wouldnt worry about the stock cats and get some high flow ones. I gained 20 rwhp with my headers. I have lid, tb, macs, ory and a cut out and got 340 hp and 350 tq. before the macs I got 321 hp and 340 tq. Im actually thinking about selling the macs.... but I sadly still have a stock converter.

Re: Mac's with stock CATS? Alright, thanks for the input. The RT cats cost quite a bit, so that will set me back a little more before I'm going to get headers. I just had the converter put in last month so can't go rushing into headers
