Dynomax headers
Is the standard Dynomax headers a good choice for my stock 1980?

get the CERAMIC coated ones for an extra $100.....the removal of all that heat in the engine bay and you will thank me later !
$210 from Jegs ! Jet-hot coated high quality, cheap performance....others will agree !

Re: Dynomax headers (Ingar, Norway)
Thanks!
Yes, if I could get them at US prices I would definitely go for the coated version.
But in a shop here Norway the standard version costs $227, guess coated will be more that the double of that. But I will check to be sure, a large portion of the cost might be shipping.
I also intend to weld mountings for O2 sensors at both collectors (TPI), will this be difficult if the headers are coated?
My plan was to use wrapped headers, since heat insulation will be especially important with the O2 sensors.

Re: Dynomax headers (Ingar, Norway)
I have been rec. the Dynomax coated for a long time since they flow great, fit great & are made from thick tube to last. These are too good to pass up. There may not be anyone on the forum running the regular ones which are different. Expect you know something that is initially less exp. may not be in the long run. You don't "need" the better ones w/ a stock engine.
Rec. the Dynomax coated.

Be real careful about where you put the O2 sensor it is real sensitive to heat. However if when you swap to TPI buy an newer system that uses a heated O2 sensor. That would work much better for your application. I use the standard Dynomax headers that are wrapped and they prevent heat transfer real well.

Re: Dynomax headers (adam)
Ylose;
I don't know if Ingar needs to worry about heat - did you check the temp on his post?
That's probably a high too! :)

Re: Dynomax headers (Ingar, Norway)
Thanks all!!
Yes, engine dept. temperature is really no issue over here....:-)
I'm still checking, but its seems that coated ones would be to expensive. I will use heated sensors.
What size of exhaust do you recommend? My plan was to use 2 1/2.
Ganey: From what I can tell the coated/painted looks identical, what's the difference?
