Would anyone know from experience if the JetHot LTs offer an improvement in ground clearance over the Hooker LTs?

 

Yes, but with the improved ground clearance some f-body owners are having issues hooking up the y-pipe due to interference from the tranny cross-member. A good muffler shop can create or modify a y-pipe to fit.

I have a set of Jet-Hot LTs in my garage waiting to go on my car as soon as Jet-Hot releases their coated dual-cat y-pipe for the headers (which is supposedly coming in late summer).

 

I can't speak for the hookers, but on my stock-height car my Jet-Hot LT's have about 4.5" of ground clearance(this is an estimate)- I can tell you for sure that the lowest point(I actually measured this) is on my y-pipe which gives me 3.75" of ground clearance.

 

i could have sworn chris at jethot said same collector location as the hookers, thats why the mufflex pipe works with em.
