Yes, another dual exhaust routing post...I did the search, but havent found a post w/ answers to my particular dilemma. I'm looking to replace my stock, single exhaust on my /forums/images/graemlins/burb.gif, 87 TBI350, with headers and dual exhaust - probably gonna opt for Dynomax Standard Series Headers and their dual kit as well - mainly due to price. If possible, I'll see if a local Dynomax dealer can install an AIR hole for me, in addition to welding on an O2 sensor bung - that way I'll be able to run their coated headers, which arent much more expensive at JEGS and come w/ a lifetime warranty. Clearly, that warranty might be voided w/ custom AIR and O2 bungs, but at least I would get the better heat and flow characteristics of the coated headers. For the difference in price between the standard series and coated series, I could hardly buy enough wrap to cover them. One of my biggest concerns is the safe routing of a muffler and exhaust on the passenger side, specifically where it runs along the frame rail, wherein sits my fuel filter and lines. Has anyone else encountered this in running dual exhaust? I 've thought about installing some custom heat shield along the frame rail, and maybe also moving the passenger side exhaust further towards the center of the /forums/images/graemlins/burb.gif. Pics? Solutions?
