None for a Mustang, but I run a 3" turbo back setup on my daily driven Volvo with no issues. I can tell that its not very think tubing, but not sure if that will make any difference or not as far as longevity
I would recomend that. With my car, there were two available...The OBX unit that was $350, or a swedish made setup that was $1100. $1100 for some exhaust tubing? Not for this guy
I have OBX long tube headers on my 08. Have been running them over a year with no issues. Actually found mine on ebay for $250. Came with 2 off-road h pipes as well. I would buy OBX again for sure.
