ok well tomorrow i am going to pull my full exhaust to check eveything but befor i do does anyone else have any ideas and if i do will i **** the gasket or will it still be good too go and one more thing would the intake manifold make that noise if the gasket goes and the its sounds fine just reving it but as soon as you starts moving it sounds like a two stroke thanks guy and girls lol

 

what year?!?

 

It would be best to replace the gaskets. I always do. After time the gasket forms to the shape of the pipes. Creating a perfect seal. if you break that apart, it may not go back together 100% flush. If it's all stock, it may be rusting depending on miles ect. But I always do it if I'm seperating anything that has a gasket in it.

 

its a 07 ss 2.4 and it is all stock and has about 120,000 km on it

 

found the problem my manifold was cracked in the middle where it v together

 

Yea I would replace the gaskets.

 

well i am going to order a new manifold and down pipe when i get back from the city so any suggestions
