Bogging/misfire under load at 2-3k

its not the question , nobody expect big power around 2k revs , but with stock exhaust it runs smooth from 1500 to 2500
and now its undriveable in this range . would understand , if the exhaust setup makes 15 horses more in the higher revs ...
Hm, i have removed cat and rear muffler and still drives like stock but it's loud and proud
 
I guess people who ride bikes understand this
i ride street and mx.. i totaly get it what you mean…. BUT …. it cannot do missfire on full pedal…. i understand that it cannot pull .. but it CANT do missfire :smile: and the biggest problem is… that it worked fine for years.. and than i slowly noticed a little and little problems on 2500 ride.. even in second gear.. until it started missfire and pulling all “elastic” with no changes to the car…. had KN filter and k-tec exhaust for years… and it worked SUPER :smile:

Check your flexis in your manifold. Common that these split and cause exhaust leak, which has a noticeable change to the flat spot, including misfiring.
