Another Header Thread

[Wagnasty]

So I was looking for a set of longtube headers and off-road Y pipe to install on my 2003 Yukon Denali. I was wanting to go with a set that has the 1 7/8 primaries, and with my searching I found that there was a few companies like calspeed, lpp, and pacesetter. I also saw that there would be fitment issues to work out due to it being awd. Upon further searching I found that calspeed and lpp don't offer them anymore. Pacesetter does but I'd honestly prefer the stainless version for obvious reasons.

On to my question. Is there any companies that make a decent set of longtubes with 1 7/8 primaries and off-road Y pipe? I'd like to find a budget friendly set for possible maybe less than $500. Do you guys know of anything or could point me in the right direction?

Speed engineering.

I have speed engineering so does ezdaar. Both of us have had no problems with them. You won't need 1 7/8 primaries unless you have some serious boost.

I have a pretty large cam and no problems at all getting the air out.

Yeah I just saw those headers from speed engineering. But they are sold out, and they told me it would be closer to the second half of July before that get any more in. I wanted to get the 1 7/8 primaries because I'm building a 408 to put in my Denali and would like to stick a magnacharger on itafter the first of the year. Looks like I may just wait for them. I didn't want to because I've got my truck apart having the transmission rebuilt.

 

[ezdaar]

For the cost and features, they are worth the wait.

 

[Wagnasty]

I appreciate the input guys.

 

[ezdaar]

Do you want to coat and wrap them aswel?

 

[Wagnasty]

I honestly hadn't thought about doing that.

 

[ezdaar]

Ebay for header wrap, you can get two rolls for the price of one from auto parts stores.
VHT header paint and a commercial heat gun to bake the paint on works very well.

It reduces the temps so much you can put your hand on a primary after a hard freeway run and not get burnt. Now that's not saying its not hot, but you wont get burnt.
I don't recommend doing it, but I have to show friends how well it works.

 

[Wagnasty]

I may just go ahead pick up some of that wrap. I'm hoping that there isn't to many clearance issues, otherwise I may not be able to wrap them without really having to crush the tubes. Thanks for recommending that. Did you all have any issues with clearance or installing them?

 

[ezdaar]

Y pipe cross over tube need to be made oval from round. to clear front drive shaft. dont dent it.

No other issues.

 

[Wagnasty]

Ok, I can handle that. Thanks again brother!

 

[ezdaar]

You realize that a denali exhaust is diff than a typical yukon.

 

[Wagnasty]

Are you refering to it not being a Y pipe? Where it's 2 pipes that go in to the muffler? Or is there something else different?

 

[ezdaar]

Yes, exactly that. What are your plans to connect a standard y pipe to the denali catback, or are you going to use a yukon style catback?

 

[Pachanga02]

For the denali 6.0 engines do you have to purchase the y pipe along with the headers? I'd like to do headers and maybe a cam down the road on my girl.

 

[Wagnasty]

I did away with the factory catback and had a local muffler shop put in a MagnaFlow. I'm not happy with it at all so I will probably just replace everything when I install the headers

 

[YukonXL04]

You can buy the headers with or without the ypipe. For a denali either have a shop make you pipes that hook to the denali duals, or buy a yukon cat back and run that with the y pipe

 

[Wagnasty]

I wish there was a way I could get a X-pipe in there and turn the exhaust out before the rear wheels on both sides but the fuel tank is in the way. I'm trying to avoid your typical truck sound if that makes any sense. The popping/clapping sound. I thought it was because the pipes were so long but I moved my muffler right up to the transmission cross member and have the outlet coming out under the running board. It still sounds the same but a tad louder.
