Long Tube Header Question?

I have a 95 with the Corsa exhaust system. My question is: How much, if any would long tube headers help the performance/ horsepower. How hard are they to install and who makes the best?

Thanks
Goose

Don't know if you have converters on the car,but long tubes will require them to be placed further back which means you will have to get a "bullet" style converters,and will have to modify the corsa system.I used hooker "2149" works for me,how ever a specific lt1 header will cost more.

The LT1 exhaust system flows really good for a stock motor.

i looked at getting long tubes on my 96 but due to the location of the cats i would have todo some other work for the long tubes to work. i decided to just get shorties instead
i will problably be blasted for that. most people prefer the LT's over shorties.

Performance is lost when emissions equipment have to be added. If you can eliminate this factor you will gain. Vettes just dont gain a lot like you would with another car because of the performance engineering. It didnt stop me, I have LTH's and when I can afford to get the exhaust tied back in, some day

,I will post my impressions. I have LT headered every vehicle I have owned except for the ones under factory warranty and have seen some impressive gains in performance. The best was out of an Isuzu Trooper!

I can't complain. JBA was even helpfull with written installation instructions, and hardware, when I contacted them thru thier website.

The guy I bought my '95 from said he put shorty headers on at first and couldn't really feel any difference. Then he had TPiS long-tube headers with a 3" B&B exhaust installed and said it really picked up how the car felt. This is a manual transmission car. Later he said he had a 4:10 gear installed. Stock was a 3:45. He said that made the biggest improvement. Not knowing what a stock '95 feels like, I would say my car feels pretty quick. That should improve after I install the AFR 195 heads & LT4 Hotcam.
