Anyone got a part # for the dormans? Thanks

 

Dorman 679-005

 

Got it. Thanks

 

I wouldn't put Dorman anything on any vehicle I own even if it were given to me free of charge. That is just another company that reverse engineers a product (a copy) and manufactures it with inferior materials and cutting corners. There was a time when Dorman was good, but that company was sold a while ago and it went to crap when they started reverse engineering stuff. Ask the guys who installed a Dorman oil cooler, or hpop line.
As for the uppipes, as much of a PITA they are to install, why skimp on that to save but just a few dollars? And then have the real possibility of doing it again real soon. It's like tripping over a $50 to pick up a $5 off the sidewalk.

 

Keith, your money and your choice. For years the Dorman up-pipes have been performing fine and for those few dollars ($275) saved I can buy a whole lot of beer.

 

This has already been posted up several times but here's a good example. I paid for bellows, I want good bellows and welds and tubing.

 

Understood. And I get what you're saying. I am very budget and price conscious, but there are just some things I personally feel aren't worth settling for. Piece of mind is cheaper than beer sometimes, lol. Just another outlook on the subject is all.

 

I can say the Dorman pipes I installed had good welds on them, and I do have a pretty fair amount of welding experience. Enough that I still catch myself referring to TIG as Heliarc . . .

 

We could argue this one 'til the cows come home but I'm with Keith here. Just been burnt by Dorman too many times to go back if I can avoid it in any way.

 

OP, I went with the Dorman brand, simply because I ordered through Advanced auto Parts due to the fact I had a discount code which made them an extremely good deal at the time. That said, I live in an area that I don't really have to worry about rust issues. I am currently satisfied with the purchase, fit, and function. Not to take anything away from any other brands. And I am picky to an extent on what I purchase for the truck. Best of luck on your decision as you are the only one who knows what you will be comfortable with purchasing.

 

Got the dormans. Will be able to afford frx soon. I don't mind wrenching on the truck. I know I will replace them in the future again. Ih will be the next up pipes

 

Dormans here as well. I hi temp primed, painted, and heat barrier wrapped them. No issues at all. For what up pipes are, I think any more than the cost of Dormans is unnecessary.

 

I have the Dormans as well.What is the benefit of heat wrap?I am going to prime and paint,just curious.

 

Heat wrap, and a real ceramic coating (not just the "ceramic" engine paint in a spray can) both serve as heat barriers. This keeps the exhaust heat in the pipes instead of bleeding off into the underhood air. This is good for 2 reasons:
1.) It generally keeps the engine compartment cooler, which is just generally a good thing for the various rubber and plastic items under there. It also helps to keep the intake air charge cooler.
2.) By keeping the exhaust gases hotter, they maintain higher velocity. In other words, the exhaust gases retain more energy, which in turn spools the turbo quicker, and more efficiently.

The ceramic coating also adds corrosion resistance.

The wrap, on the other hand, tends to accelerate corrosion; especially on uncoated pipes. In fact, most header manufacturers instantly void your warranty if you wrap the headers. While the retained heat doesn't help, I think the biggest cause of excess corrosion with wraps is that they retain moisture, and hold it right up against the metal for sustained periods. Heat + water + road salt,etc.. = rapid rusting. Now, in our up-pipe application, I suppose they are subject to LESS ( but not zero) road spray vs headers which are closer to the wheel wells.

I would definitely do the ceramic coating if you can. I probably would stay away from the wrap; especially if you aren't also having them coated.

 

Yea the wrap has rusted out my motorcycle exhaust. What brand or where can I get these ceramic coated?
