I have sealed all wholes in firewall and the spot under shifter (since mine used to be a manual car). Looking to get any other suggestions so that after I go for a cruise I wont smell like exhaust! Where else to seal that im not thinking of, what else to do ..

Where does your exhuast exit?

exits around the rear axle area.

Theres always going to be air coming in. Maybe your exhaust manifolds are leaking and it's coming in through your hvac intake?

whats a good way to check for leaky headers. I dont hear any ticking from them or anything like that.

Define "around". UNDER the car? Out the SIDE?

If if exits UNDER the car.....that is "the problem". Got a pic of the exhaust exit location?

yea its right under the car around where the ujoint and rear axle is. moving it to rear and outside would make that much difference? like to have it not showing.
and wanted to stay away from going over the rear axle, any other suggestion to routing

You could turn it to the side & exit it right in front of the rear but then you can run into ground clearance problems, depending on how low your car is. Use an oval exit & that helps with ground clearance out the side.

I almost did the side pipes, but ran out of scrap pieces to make it. Also got tired of laying on back on and off the car to weld. lol.

Silly question... What do you have for breathers/PCV setup? Is it factory or do you have open breathers?

Perhaps you have an exhaust leak by your headers, and that which is leaking, is sneaking into the holes where the Heater Core goes through the firewall, then the air from ac/heater is pushing that exhaust leak into the vents, and onto you.

Will have to continue to track that down. Hoping to find it soon. Thanks

I bet if you had some sort of tailpipes sticking out from under the car it would take care of it, i had the same problem with an old car i had a couple years ago, the exhuast turned down at the rear end on it too, i finally broke down and put some tail pipes on it and it took care of it.
