im starting to smell some slight exhaust fumes in my cabin, so im thinking i have an exhaust leak. but how do i know for sure? and how do i check?

im using the drag kit that came with no gaskets at all, and ive been suggested not to use silicone gaskets either between the mani and the dp and mani and turbo. how do i find the leak?

im also wondering if me scrapping my cat cuz my cars too low has anything to do with it.

 

listen for it, try idling the car next to a wall or in a garage (with open door ). sometimes its easier to find having the sound bounce off something

 

i used to have that very same problem. To find it, i had my car jacked up at an exhaust shop, and had them weld it for about $20.
