I just purchased all the braces for my g37s coupe. I hope it clears the hks exhaust!

 

To anyone who has installed all of the GTSPEC braces (excluding the FSTB and fender brace)... Was any drilling/modification required, or do the braces simply bolt-on to existing holes in the chassis/subframe?

Also, are there any IPL owners who have installed the lower lateral reinforcement (M shape) brace? The description states compatibility issues with certain aftermarket exhausts. Is there any compatibility issue with the IPL exhaust or is that section of the exhaust the same as other G coupes?
