does anybody know wherer i can get a 3" exhaust kit that will fit my 79 4wd 150 with a 390 out of a 73? if nobody sells a kit then i will just order a builders kit from megs exhaust and build my own but would rather buy a kit

 

When i did the conversion on my '73 high-boy I couldnt find a kit... so i just ended up going down to the local muffler shop and had them do it for me... I will suggest however don't go the way I did with the glass packs... that is if you ever want to have a conversation when driving down the road... :P

 

All the kits i ever found were for the stock diameter piping
