Great product
By Gary G. Kish
I used these headers on a LT1 350 V8. I've put headers on about 80% of the cars and motorcyles I've owned and these where the best. There was no pause or waiting for the tach to climb before the power hit. It was instant! Very strong low and mid range, yet still have the big power scream on top. Other long tube headers always seemed gutless down low, until they hit. I never thought much of it until I tried the Afterburners (great name)and had no lag or waiting. It later showed on the before and after dyno run I had. I have to dig it up as it started as soon as the dyno operator was able to hit the throttle (I think at 2,000-2,500 rpm) It showed the same power increase right though the run, with no dips or peaks. The car felt like it had a big block in it after I installed them.I had sent them to Jet-Hot before I installed them just to keep the temps down but I don't believe that had anything to do with the hp increase. This is a weird design for headers but so are most cars that have factory tubes over a manifold and I believe the Nascar ones are very similar to the Afterburners design. It's not easy getting a patent and Flowtech has it with the Afterburner design which says something.I would only recomend you properly coat them, not only to keep heat down but to make sure they don't rust (which everything but stainless seems to). If you Jet-Hot them, don't spill oil on them afterwards. It ruins the look completely when it bakes. I also ran them with an X Type and dual mode mufflers. It was the wildess sounding Roadmaster LT-1 in Michigan, and with the torsen rear diff and low gear pretty darn fast!Gary
