I am doing a typical 6.0/4L80 swap and doing mods from a D1Procharger and cam to mild suspension work for a tow vehicle out of an '01 Sierra. Wanting to know how some headers preferably long tubes are; price, specs, material, and personal. I was looking at a set of Texas Speed long tubes ceramic coated, let me know what everybody thinks.

 

Speed Engineering hands down. Cheaper than TSP and the same product for all intents. I have SE's 1 7/8" primary long tubes on my 2004 light duty 2500 and they are honestly one of the best fitting headers I have ever used. And for the price..... can't beat them.

 

Just installeed a set of Speed Engineering's 1 7/8" and their true dual system (no cats) on a buddies 2001 2500HD. Perfect fit and finish, and VERY attractive price. Just be sure your motor mounts are new and not sagging.

Headers only

Headers and Y Pipe

True Duals

 

Same as above.

 

ARH or Kooks if quality is important, if price is more important TSP or Speed Engineering

 

Lol. What "quality" exactly beyond the price tag. I have owned those expensive things and had fitment issues, grinding needed on edges etc. The welds are nice on the cheapies... The tube and flange is thick and it's T304... but hey... Go pay $1600 plus for something else lol.

 

I agree.

 

I've had both 1 7/8 and 1 3/4 speed engineering headers and y pipe on my 2008 sierra Denali. Had to make my own adapter for y pipe to bolt to factory 3.5" cat back but other than that you couldn't ask for better fit and quality.

 

Running paceshitters 1 7/8 here, no problems at all. Fitment was good, but looking to sell these at some point and step up to TSP or speed engineering. They look like best bang for buck.

 

if you are on a budget and don't mind chinese headers then TSP or Speed Engineering will get the job done, Ive had both and the fit, finish, welds etc are much nicer on my ARH headers...the chinese headers are knock offs of the real thing, no different than a chinese rolex, yah it will tell time but you are kidding yourself if you think they are the same quality
