how much does a header leak affect performance? ok i had my Hooker lt's installed with brand new stock GM gaskets and i had bad leaks at the heads on both side... so i swapped out the GM gaskets for Percy's seal for good gaskets and still leaking... i assume it's leaking cause theres a fluttering/ticking sound when im under medium to heavy throttle... it sounds about the same after i switched gaskets but i noticed my car runs stronger now... so how much does an exhaust leak at the heads hurt on power??
i'm wanting to get my car tuned asap but i can't decide if i should go ahead and do it or continue to try and fix this exhaust leak first!
what do u guys think?

ok will do.... how can i tell for sure that it's leaking? i'm almost positive it is but maybe i'm just paranoid... i'm mostly basing it on the fact that this car sounds alot different then my last one did which was a 2001 with pacesetters... whats a good way to check for the leak?

To check for leaks I go over where all the connections are on the collectors, y-pipe, intermediate, over the axle, and muffler. I look for any black exhaust markings.
I also use Percy's seal-for-good along with Stage 8 locking header bolts and have never had a single issue with any leaks...

well the only place it's been leaking is at the header flanges... everywhere else is sealed up good. i also used the Percy's seal for good gaskets but i'm almost positive it's still leaking at the flanges so what is the best way to test and see if i have a leak around the flanges??

so can somebody tell me how i can test to see if my headers are definately leaking at the flanges? i want to know for sure before i pay again to have them taken off and messed with... if i find out they def are leaking im gonna take them off and have them milled flat and maybe even use some rtv.... i want to get it tuned asap so this leaking is killing me.
I would say pull them of and check to make sure that they are a flat face. You have gone through and re tightened all the header bolts i assume.
why dont you just pull them off yourself? It jsut take a good buddy or two and an (i believe) 10MM socket
