    2010019 is rated 5.0 out of 5 by 5.
    Rated 5 out of 5 by from Perfect fit, great quality 2001 Silverado LT Ext cab, 5.3L, 4x4 - Install was relatively easy - you WILL have to drop the transmission crossmember (passenger side only, 3 of the 4 bolts, only about a few inches) to get the passenger side cat-pipe in. (You can cut the original out to save time.) YouTube has a couple good ideas on how to do this... I installed the Flowmaster American Thunder cat-back muffler with it to complete the system. Couldn't be happier! (I will weld the connections when I get the time...) She has a nice rumble!

    Rated 5 out of 5 by from Great fit! Purchased a couple weeks ago everything fit great ..good clearance on all oxygen sensors and alignment with manifolds and Muffler were spot on. The only negative was a small pin hole leak in one weld....not a big deal.

    Rated 5 out of 5 by from Good price Installed on our 2004 Chevy 1500 Silverado 5.3 engine. I have read other reviews on lesser products and they all said they rattled. This product did not. No problem with coding any sensors. Works just fine. Also installed cat back Flowmaster exhaust. This was professionally installed.
