I know the exhaust leak is affecting my performance but the question is how much..I have an exhaust leak coming from either the collector flange or passenger side header..And you know how cramped that area is..So how much HP could I be losing with a leak like that?
Exhaust leak affecting performance?

Keep it lubed .... keep it straight .... and keep
Don't know how much .... but when I had a leak at the passenger side collector, it was a SOTP difference. So I imagine it's enough to make your car run like crap. At least it sounds like an easy fix. Mine was ..... just put the car on ramps & tightened the collector stud & all is back to normal.

Well that particular leak may cause a noticeable performance loss since it's before the O2's. BUT, when my Summit pipe used to come apart at the crossover I could feel the difference by SOTP probably caused by a loss of back pressure.

i fear i have a small exhaust leak from my summit aswell, i think it's @ the passenger side connection between header/hpipe (before 02's). I'm going to get the crossever segment welded together on friday so i can take that damn clamp off as it just seems like im on burrowed time with that thing. Another terrible thing about the clamp is that at school we have long speedbumps and if i don't pretty much stop for them the clamps screws scrape and it's embarassing. Back to the previous Q, if the exhaust leak is before the o2's it can cause improper o2 readings and depending on the size/location of the exhaust leak it can lead to a loss of backpressure and to much of a loss of backpressure will result in a loss of torque.
