Ground clearance with headers
Well I got the headers on the LS-4 earlier this week, looks to be a little over 4.5" of ground clearnace to the header flange. I got the rest of the exhuast hooked up to the headers on Tuesday, I'll be taking it back since the passenger side has a real nasty crimp in it right after the header :( . Anyway just wondering what some others have for ground clearance and if I should worry about speed bumps etc.
thanks

4.5" from lowest point of header to ground? That sounds like a lot to me!! I think I have less with my regular exhaust pipe. You would always want to go over speed bumps extremely slowly. I approach at an angle so go over almost 1 wheel at a time, and so slowly sometimes I dont make it and roll backwards on the first attempt. MJ

About the same as mine. No problems. :cool:
Since the headers point down some, make the upturn in the widest part of the reducer & the header flange will be the lowest point.

Give it much more gas !

Yes, you have to be careful, especially on the back roads, some slight dips can scrape (I know :( ) But, 4.5" seems like great clearance for headers

Mine touches everything.....I'm going to take her in and have them shave off the lower pointed tip that's nicking everything above the pavement surface. I have to be very aware of every bump or curb I climb........Talk about low?......Sparks fly from my knuckles as I cruise by the pool hall at night.... :lol: [IMG][/IMG]

I don't have my car back down on all fours yet from suspension and headers etc, but it appears that I will lose about one inch from before. Give me about 4 inches ground clearance.

Re: Ground clearance with headers (73 LS-4)
I have (had) 4 1/2" clearance from the bottom of the header flange and had no problems with speed bumps, just dips in the road. I just installed heavier front springs so we'll see if that fixes the dip prob (the new spring only gives me 4" clearance, but is tighter).

4.5" ... I'm jealous.
I just got my new 17" wheels on and I have a modified suspension ... guess what my ground clearance is.
Give up? 3.2 INCHES WAHOO! Does this mean I win?

Thanks everyone for your replies, I was glad to see the ground clearance as much as it was after hearing all the horror stories before about dragging them on everything.
