Works great so far been a few weeks does smoke a little after installation
Most Liked Negative Review
Absolute garbage - typical Dorman quality
Yes, this part will fit and initially resolve an exhaust leak. If your intent is to keep the vehicle in which you install this part for more than a year or two, do not buy! You can find the OEM GM manifold online for around the same price and won't have to do it twice in a year! These Dorman manifolds fail...period. I've purchased many Dorman manifolds for several makes and models and they all crack over a short period of time. This right side manifold on my 2004 Denali 6.0 lasted only one year before one of the runners cracked completely through. FYI...I used GM hardware and torqued to manufacturer's spec. Dorman products are typically low quality...you get what you pay for! As an ASE certified tech I've used many Dorman products when in a pinch and it always comes back to bite me.

What brand of headers would be an exact fit for my 2002 silverado ls
Verified Reply - Steve
Hi Michael! Since you didn't mention the specific sub-model and engine size of the vehicle, it's hard to tell for sure. To give you the correct information I would need the sub-model and engine size of the vehicle.
Why is the right side manifold twice the price of the left side?
Verified Reply - Steve
Hi Chris, please provide the left side manifold part number to check the difference with the Dorman - OE Solutions Exhaust Manifold Kit (Part No. 674-732). Also, please provide us the year, make, model and engine size of your vehicle.
