FYI to those contemplating new exhaust, I just received my truck back from the muffler shop. I had Mike Yoder in Kansas split my stock exhaust-did a REAL nice job-in fact my mani was cracked so he pulled one out of his stock with the same casting number and made it out of that,($185.00). Then I had the muffler shop run dual exhausts with stainless & glasspacks out the rear. Sounds nice/quiet the way I wanted it. Yoder's method allows you to keep the stock heat riser and carb. The exhaust wasn't cheap but the whole setup is close to stock and less that new intake/headers/carbs/linkages etc. So far I'm happy.
