i have to doug thorley header on my yota and the only problem with it is it was welded incorrectly and leaks, i have the stock manifold for it. Am i going to notice a big loss of power or different sound going back to the stock manifold. i also had a pacesetter which also leaked horribly before the thorley, i dont have many mods besides the afm meter mod and rv cam. im just tired of the. although doug thorley offered to fix it if i sent it to them, i jsut rather fix it without dealing with bs. thanks

 

uhm..just take it off...put your stock manifold back on..and send it off to Thorley...then you can either put the header back on..or sell it?? a leaky header wont sell too good..lol

 

^indeed that stock manifold won't affect anything. it was on there in the first place from toyota..... so yea.... you won't notice much.

 

yea im tired of these headers lol i might to put the manifold back on
