I Want to redo my exhaust on my 03 silverado I want to replace stock manifolds with headers then X pipe to dual super 10 flows but my problem is will I have enough ground clearance for full length I have a 4/6 drop and I don't have much clearance now and every car or truck I've put headers on in the past one of the headers always stuck down lower than the other but I've never measured how much or how much past the frame it sticks down ill use shortys if I have to but the only thing I've ever noticed out of them is sound difference so I'd rather go full length

 

4/6 drop on a truck shouldn't have much issues really. Unless you wanna run bigass mufflers lol. Magnaflow X-Pipe with those mufflers shouldn't be an issue. Id be more worried of your bumper than your exhaust.

 

Yea I can't keep a valance on there lol

 

Frame will bottom out before headers do

 

^^^ Exactly. Even junk china headers I have seen sit up above the frame rails.

 

I have a 2001 silverado with texas speed long tube headers and 3 inch y pipe. Everything stays above the frame. No clearance issues.

 

Good I just wanted to make sure on my 96 silverado with 5.7 one side was lower than the other but I couldn't remember if it was lower than the frame or not so thanks for info
