Use of TTI headers

And the thing is, there probably isn't 20 HP difference between those and the high dollar ones. Arguments incoming. lol

Well, imo on a VERY serious engine the bigger headers MIGHT be worth 20 over the summit ones, (maybe).......
but I'll bet there's not five hp between TTI's and summits on 400 horse motor. Again, my opinion.
