I have a 99 Cobra and going to put exhaust on it. Is it worth doing headers or do the stock ones work well enough?

 

That depends on what your ultimate goal is with the car as well as current mods.

But outside of that.....is around 20RWHP/TQ worth it to you considering the cost of parts/install? You could see less than that as well. Could see a little more.

 

To me, its not worth the cost. Just going to do an x-pipe and cat back
