b16a slight backfiring and pops after header install
ok I installed a header on my 89 hatch with a b16a 1st gen swap, everything sounds good until i shift or let off the gas, when i do i get a small but noticeable crackling and small backfire, ive noticed this in all civics, integras that have aftermarket headers, but what actually causes this?

Re: b16a slight backfiring and pops after header install
Make sure there's no leak on your header gasket and tighten all bolts properly... Popping and backfire usually caused by leaky exhaust.
