well, if the exhaust was all you got installed, you're not gonna feel any huge power 'increasement' (is that a word?). sorry, i had to....

as for your idle, i don't think your exhaust will affect that. maybe somebody else can help you....................

first, what car? second, did you change the cap? rotor? pcv valve? fuel filter? last, you did all these things before, after, or at the same time as the exhaust? when did you notice the difference?

I really doubt its the exhaust I have a greddy evo exhaust on my car and i didnt lose anything. You may not feel gains from a catback exhaust (in fact you most likely wont) But if you are sure you lost power look for a problem elsewhere.

the butt dyno should never be used as a way to determine whether you make or loose power...the only way to determine this is a before and after dyno.



Performance Chart
--------------------------HP Level-----HP+-----TQ Level------Q+
B Baseline Power-----105.5 *--------------------99.1 *
1 Intake----------------108.1---------2.6----------101.3------2.2
2 Exhaust--------------110.0---------1.9----------102.5------1.2
F Final Power----------110.0---------4.5----------102.5------3.4

tuned and mated with a intake...only gains were barely a 2hp gain and 1.2trq+ from a greddy evo. Dont be surprised Honda made their cars to a standard that aftermarket parts wont make that much of a difference. There is very little leeway to make an aftermarket bolt-on kit make a huge power increase
