BLACKHORSE-RACING Stainless Shorty Exhaust Header System Compatible with 1999-2001 GMC Sierra 1500 2500

I was very unsure about the purchase of these headers. The price didn't set right with me thinking they weren't of good quality. I dropped almost 600 bucks prior to this purchase of headers on another set for another vehicle I have. A high end company and let me say this im upset I didn't purchase bothe sets from dark horse racing. These headers are most definitely a high end built product. The welds all look like some one stacked dimes in them very clean no burn throws anywhere the stainless steal is very thick an excellent quality. I have showed these things to all my hotrod buddies and they were amazed just as I was. I know I sold another 5 sets for dark horse over the weekend. Do yourselves a favor buy these headers u will not be disappointed in any fashion. I will be a return customer an I will be pushing darkhorse products to my fellow gear heads every chance I get. Thanks Darkhorse racing. Please keep up the quality work with ur products. Very very happy customer here.

These were an absolute perfect fit for my 00 sikverado and just 95 bucks cheaper than the 2 previous orders that had to be returned because they didnt kick down in the proper place . The seller sent them to me immediately because they came 6 days early.

Bolted right up no problems I put them on a 02 4.8 and worked great only issue I found was with the spark plug wires but that does effect the product very happy with them

Couldn't tell a difference in sound or performance forreal

Welds had holes. Flange welded on sideways. Maybe for a different truck. Not mine.

Came with everything I needed. The sound of the stock cam can be heard easy now with a super 10 muffler. Not too loud a deep tone

Driveside flange was off by a lot for a lot for a 2007 chevy 1500 5.3.I guess you get what you pay for

Made a big difference
