LTH hp gains?

[Wookie107]

What’s a realistic hp gain with adding long tube headers? 2021 gt.

on the 15-17's you could expect around 20 hp, on the 18+, a little more.

20whp is fair. If available in your area tune for e85 or flex at the same time and you'll really transform the car.

Thanks. I couldn’t find any definitive info on the gains. I do have a gas station down the road that carries e85. Planning on a tune next spring and thinking about doing the headers over the winter while she’s hidden from snow and salt!

The 18+ engines really love E-85. With just LTH's, a good CAI, and a e-85 specific tune you could knocking on the door of 500 whp

I'd suggest just tuning for both at the same time instead of separately, no need for revisions etc.

That’s what I did (93, Flex and E85R). I had to pay separately for the E85N tune.

20+ rwhp is pretty common for gains when going with LT's. I personally think the most potent and cost effective combo to make power on the 18+ cars are LT's and an E85 tune. After that it's Whipple time!!

Let us know if there's anything we can help you with.
