TTI Clearance

It's not uncommon to have to shim the engine mounts up on one side or the other to get some clearance with the TTI or Doug's headers. Well, any headers really, but the less expensive headers people usually just dimple because they're too far off for a shim or two to fix things. Even TTI's and Doug's need some dimples added on some cars, just the nature of the beast with headers on these cars. The tolerances on these cars are pretty loose, and header clearance is at a premium. Even the expensive headers usually take a little work.
