i got me some long tube headers and isntalled them but my h pipe is for shortys and is going to have to be cut to connect to long tubes but i have to take my car to muffler shop, will i do any damage to motor if i drive it open headers for a day

 

It'll just be loud as hell and probably sound like an old bronco.

 

drive it at night so you can watch the flames

and no it won't hurt it

 

cant i mess up my valves or something like that or is that only with shorty's? im probably going to wake up the whole block in the morning when im on my way to school which is like at 6:30 am

 

it will hurt if its over a certain amount of time

 

Just take it easy. And remember it won't sound cool. It'll probably sound like straight up ****.

 

Why did you buy long tubes and not the corresponding pipe? Or Consider the shop time to get it done in the first place?
