I am looking to get straight pipes out the back of my 88 K5, but when i go to my local 4 wheels shop they say they cant do it? Now i was reading a post earlier from "Mudnurl" and in one of the reply's some one said something about running them outside the frame? Is this because of where the fuel tank sits as to why they cannot get straight pipes. Sorry if this is useless question, but you all are my source for knowledge on my K5 until i learn all of it myself. Maybe if you can post a link to where i can get or have a shop fabricate some would help. Or even just reply as to if a local pipe shop fabricated some.
