yoo sup guys.

just putting my exhaust on my car

my setup right now is:  
S13 vert chassis  
red top sr20det  
Nismo engine/tranny mounts  
stock manifold  
T28  
3" Circuit sport elbow

problem:  
3" ISIS downpipe, but its touching the top of my floor.

i was told to smash the floor out of the down pipe’s way. im not sure about that. any other suggestions or anyone ever came across this problem?

Thanks  
Jacky

Put a wood baseball bat on your jack and jack it into the floor where you need space. This will give the down pipe enough room and leave the floor looking like it was factory indented.

You dont bassshh things Dylan lol…Bash the down pipe if anything.

+1 or use a length of pipe of the same diameter as your downpipe ( 3") and jack it up. Just make sure you secure the pipe to the jack or you could slip and damage something important.

Could you just get a different down pipe or do they all do this?
