I have a 1993 Class A chevy motorhome and am considering installing a set of headers. How terrible is the job and what is the most cost effective header? Do all the systems run the dual headers back into single exhaust?

Thanks,

Dave

It really depends on the vehicle. Most class A have room to do the install versus say a class C that is on a truck chassis.

Get a good set of headers to start with. Ceramnic coated are probably the best to help remove the heat from the engine compartment.

I would soak all the old header bolts with some sort of penetrating oil, like PB Blaster or Kroll Oil. Breaking a rusty nut/bolt can ruin you day.

The next problem will be cutting and attaching the headers to the exhaust system. In many cases is easier and cheaper to go from front to back with a complete new system. If you remove the old system first, you can install the headers from underneath the coach, install the connecting pipes, cats, mufflers, hangers, tail pipes, then adjust for clearance and lastly tighten up everything.

I'd like to second Dale's recommendation that you start with the best hedders you can find/afford have them aluma-coated [one name brand for this service is "Jet-Kote"]. You should also brace yourself to experience one of the most frustrating installation situations in auto mechanics because: "there is no such thing as a 'bolt-on' hedder!"

While you may have a Chevy engine, & every aftermarket manufacturer makes hedders for it, YOUR PARTICULAR INSTALLATION WILL BE DIFFERENT!

Recognizing this necessary "custom fitting" up front & the actual work is a piece of cake!
