I just got my notice that i have to do emissions testing by the end of august, so i figure it's time to put an exhaust on the truck. It's an '87 RC 4x4. Would it be possible to have the exhaust exit right before the rear tires? is the only option to route it under the frame? if that's the case then forget it i don't wanna lose any ground clearance. any on here done this or think it may be possible? and is there a kit i could buy or would it all have to be custom from a shop? What about using those "universal" truck dual exhaust kits? thanks for any help!!!
