$107 4th Gen F-Body LS1 Long Tubes on 67 C10/C20

[ZforSpeed]

I saw a post from BossHog69 and he left some pretty good review on a pair of Ebay headers.

I found a similar set from the same vendor for some 4th gen F-body LS1 long tube headers for $107

Has anyone had any experience with installing these 4th gen long tubes on your truck? Or any other 4th gen long tubes? I'm thinking of trying these on my 5.3 C20/4L80. I contacted the ebay vendor and they're less than 10 miles away. Worst case, I'll have to pay their 15% restocking fee.

Thanks Fellas!
