94 chevy S-10 p.u. 117.9 in. wh. base, i want 2 replace the middle pipe,muffler, and the tail pipe. i dont want 2 replace the catylitic or the manifold pipe if i dont have 2. i got a rust hole about 3 or 5 inches from the catylitic converter. the pieces are welded.
get a tape measure and crawl under it and measure, then get a little more just so you have room to work with it.
Just buy a preformance exhaust system and replace the whole thing for about $300. Adds about 30 - 50 HP around 17- 20% increase, and increases fuel efficiancy.
is the rust before the cat? if so plan on the hole system. most exhaust rust from inside to out as moisture settles inside the pipe with excception to cars driving in snow conditions, and unless you replaced the Cat converter its probably not to happy, the other answer you got was pretty good pipe wise. measure your overall exhaust pipe Lenth and add around a foot for bends (each)
