Ok i wanted to see what people actualy have for realy dyno sheets and actual gains.... i know the singles are sup to make the most ect.
but i am looking for real prof of which type and model makes the best power gains all through the power band. I also understand every dyno and setting along with weather and suport mods will effect this test

 

My advice would be to just get the lightest one you can afford or find a good deal on. I think HP gains are less beneficial than the massive loss of weight that you can really feel.

I have a JIC single that weighs in at around 13 lbs compared to the stocker which is closer to 60lbs. You can really feel that weight difference.

 

I had the mugen DOUBLE on for a while, and you could still REALLY feel the weight savings on acceleration. I can't imagine the savings of a single.

 

yea i just wanted dyno postings...... but you guys also have good input thanks

 

go to the comptechusa.com page. They have dyno charts to back their cat-back. The sheets note a +3whp gain.

Here is the link:
