Mid Tubes headers?
#11
Once again I apologize for my lack of computer skills.

scroll down to lt1-lt4 modifications and click
on the top right is the search , click and type, proven hp from lt headers
it should be the first post.
It's just no one dyno's their exhaust systems, I did and so did the other 3 people. I have never seen anyone bolt on a set of longtubes on a LT1 and pick up 25 rwhp on a dyno.

down farther there is one guy that says the shorties are adding good hp and only gained 2 hp by adding lts but no dynos. on the other side one guy also says he gained almost nothing adding shorties. judging by the variables and that the uper gains from the shorties are the same as the lower range of gains with the lts i would say its possible either way, its possible to have almost no gain switching from shorties to lts and its also possible to pick up a good gain doing the switch.

True dyno proven exhaust gains. Shorties have a 3" collector.

in a latter thread 96lt1m6 said he gained hp by going to long tubes over his shorties.LS1TECH - View Single Post - Long tube vs shorties on a lt1..
speed demond said "I went from 276rwhp to 303rwhp with lt's and a mailorder tune." im going to guess stock manifolds to long tubes. LS1TECH - View Single Post - Long tube vs shorties on a lt1..
and a guy with an lt1 corvette said he gained 15 hp going from shorties to long tubes. LT1 shorty vs. long tube header results - Corvette Forum
