We have installed many TPIS headers on an ls1s and have gained 14-17hp on the dyno. The cars have had only bolt on parts for mods. We then proceed to delete the cats on one of our customers cars. 7hp was the gain with no cats. Its my opinion the deleting the cats is not worth the time,cost and SMELL!
Gaining 45 hp with LT headers and no cats is not realistic. Maybe 20 or so is.
I also believe shorties is a waste of money compared to the gains. Unless, you want something to bolt on where removal might be necessary. You will gain good power from long tubes and the TPIS headers can not be beat for the money!
hcvone- send me an email! Are you ready for your first mod?
