i have a gsr with i/h/e, the header specifically is a 4-1 racing so clearance is a terrible issue, i was told by a friend that if the header scratches the floor causing a dent on it, theres also a bad side that the motor might mess up as well?, or is it just the header being damaged? i kno that the dent will hinder some power. I shrug my shoulders...help with some answers?

 

When you dent a 4-1 badly, you dent the bottom and the backs of the pipes emerging from the head. Heck, this guy discharged his airbags:

yah man...i remember looking at that thread...ouch!...but ya, any possible harm done to the engine with the header just being dented.

 

I suspect that you could pull the header bolts out of the head if the impact torque is high enough.

 

yah..that y ive been really slow on dips and what not, good thing im getting new headers very soon. and a skid plate or some type bottom shield.

 

there's no possible way it can harm your engine.....it may cause the air not to flow as smooth...

 

thats what i thought, when my friend told me that, thanks ....btw any one know of a universal type skid plate for like 4-1 headers, or the expensive tri y headers that are being produced now?
