Not a Lightning but I ran them on a mustang I used to have, with 0 problems
Any hp gains? Or mostly just sounds better? And also when people are removing their existing headers has anyone had to use an impact gun to remove the headers from the midpipe? I can't get mine off for the life of me
You not going to see a huge gain in hp from a set of Long Tubes unless you running a built motor and kb/whipple setup. As far as getting the bolts loose, get some PB Blaster and spray it on there. That stuff works better than WD-40 does hands down. Let it sit on there for a few mins. and then try to get the bolts loose.
