I took my car to the shop, and they said the factory gasket wont connect the header to the downpipe, wont fit.

What gasket do I need? Or should I double up the gaskets?

 

theres no reason it shouldn't work

 

I dont know, they told me I had a leak, so they needed to get a new gasket, he went to chevy and got one, said it was too small? So I told him to use 2.

The sound its making is horrible. So I have no idea what it is going to sound like now.

 

maybe ur dp bolt are too long
