I am installing a borla manifold and megan 02 housing and cant decide if I should get new gaskets. I have done the manifold on my older evo and the stock gasket worked fine. I know a lot of you say it will be better safe then sorry but is it really necessary? Car has 8K miles on it so it is fairly new.

 

Depends on the gaskets, but I'd say just replace them so you don't worry about exhaust leaks anywhere!

 

I used the gaskets it came with and they leaked after a couple months. I put the stock gaskets back in and have been fine since

 

I use the stock gaskets...

 

I bought I new stock gaskets. You just dont know. Like stated before better safe than sorry.
