Custom 3.5 inch y pipe....

[NORCAL SS]

Seeing if anyone here would be interested in a custom 3.5 inch y pipe. Im thinking about keeping my stock manifolds on but doing a custom 3.5 inch y pipe with 2 high flow cats.

Highly possible, but aren't there already cats on the headers? I'd rather drop any extras

Prob run 2 magnaflow spun converters. I need to measure what the stock piping is on this truck because dual 3 inch then to a single 3.5 out would be nice also.

Hell ill look at the kooks and arh y pipe set ups because you could **** just buy a 45 end and a 3 bolt flange and might be cheaper just to get a kooks or arh y pipe

Tony, does your truck have the 3rd cat? I've been debating on gutting my stock cats as they have to be the biggest corks on the stock system.

 

[NORCAL SS]

yes i have 3 cats on mine.

Just poking around and Magnaflow shows a y-pipe with converters for the 6.2 p/n 49631 but no info of which cats or piping size...might be worth a look.
