I have a 1996 chevy k1500 with the 350 vortec that has 230,000 miles and is still going very strong. my question is a little technical but I hope someone can give me some insight. it currently has the stock manifolds and pipe/cats to the point where they bolt together. after that I have dual 2 1/4 pipe going into 2 cherry bombs and then exiting out the driver and passenger side. I love the throaty groul I have right now.
One thing that has bugged me since is the dinky 1 7/8" pipe from the headers on it. it just seems like thats way to small and its even smaller in some of the bends! so my question is how much gain would I get from replacing the dinky pipe with 2 1/4' or 2 1/2" pipe. I figure I can do it for about $150 and I also think it would be a fun project. I read somewhere that someone replaced thier exhaust with one from a 2500 truck and gained like 2 mpg. would the difference be that dramatic? I would also like to put in a H pipe but Im not real sure how much difference that would make overall. my other question is the cats would I be able to stretch the pipe on the cats big enough to fit the bigger pipe or would I be better off getting new high flow ones? any recomendations? My last question is what size collector do the stock manifolds have so I can know what size flange I need. I want to stay with the stock manifolds because of reliability. thanks guys any help is greatly appreciated!
