Did you replace the gaskets?

 

i put the stock header gasket (which is in good condition) on bc the one that came with obx header was bad already.. the gasket between the downpipe and testpipe and the testpipe to cat back havent been changed..

 

Change those gaskets and see if that helps.

 

ok i give it a shot to see.. thanks for the help

 

i disconnected the stock header from the downpipe and i turn it on... i know it sounds loud but i did it to see if the flickering noise would quite down.. despite the rumble the car makes when disconnected from the downpipe.. it still made the flickering noise.. so i know now its not the gasket.. its sounds like its coming from the head....

what i am gonna do is disconnect the header and turn it on.. i know that crap is gonna sound loud but its to see if i could hear the flcikering noise.. if i do.. what might be???

 

prob fix: the stock header and gasket were in good condition. from research and opinion from a mec .. the sypmtons seemed as if the car was low on oil but when i check for leak.. the oil filter had a leak an oil change later and a addtive.. car is sounding beautiful and quiter than ever..

 

Good stuff bro
