Customer Reviews for 2.25" Outlet Exhaust Header for GMC Yukon 4.8L 5.3L for GMC Sierra 1500 99-01

Good set of cheap headers. Flanges are good in thickness and even included collectors with o2 bungs welded in. They are currently being used for mock up with ls swaps

Fits great on ls swap cars fast shipping good price. I will be buying more sets.i bought 4 set Ms because the price was so good. I used them on fist gen Camaros.

Its being installed quite a while, its works perfect does not let me put a picture is to big my files. It works perfect and looks great still. And will still

Span between outer bolt holes on left header was about 1mm too much, making it real tight to get the bolt at cylinder 7 installed, but I was able to without enlarging the hole. Even with that, I five it 5 stars for weld quality, high polish, and quality hardware included. Good packaging and fast shipping, too.

Really well built. And the price is great. Bought them for my 1987 GMC. They look great. Nice and polished.

Headers look good, had to do a bunch of modifications ( a lot of grinding, hammering, etc) to get them to fit, but that’s the case with most headers I’ve ever bought!

These are some sharp looking headers. Polished to look like chrome with all the gaskets and hardware. Even has places for O2 sensors and plugs. Very happy with the thickness of the metal and appearance.

Looks to be correct and match my old ones. I have not installed on truck yet. Will update when installed.

Greatly built product and allows my Audi A4 to breath better with noticable power Increase while sounding a little louder with a deeper tone. Way cool! Vevor was very helpful and I received it without glitches. I will definitely buy more products because of the great service and great products. Thank you Vevor for making my day :)

I have this in my 1.8t passat and it works as it should. However, I did have to modify the bend in my exhaust after this downpipe because the angle changed with this converter pipe. This pipe did not match the bend that the catalytic converter which required me to make the modification. Maybe this would be the case for you or perhaps it was unique to my situation. Otherwise, this pipe does the job and works great. The only other notable thing is the back o2 sensor port doesn't have a lot of clearance when installed.
