Is it worth it to upgrade?

 

Yes - shorties don't get you much over stock manifolds except a prettier engine bay.

 

ill second that

 

I'd honostly like to see some dyno comparisons between the JBA's and LT's. If mine are doing nothing, how much more would I make with them (LT's)????

 

DO IT.... you will not regret it. better sound, and more power all around.

 

My shorties seem to work ok.

 

wouldnt you lose boost with your LT's? thats why alot of boosted people run stock manifolds plus the scavenging effects unless this theory applies only to turbos. im sure the shortys do something or they wouldnt be marketed so much. IMO they are a decent deal if you dont want to mess with ANY ypipe or post header exhaust stuff upon install.

 

You won't lose boost with a supercharger using LT's.. The potential for losing boost with LT's is with Turbos, due to a possible loss of exhaust velocity, which is of paramount importance for spooling the Turbo.

 

ok thanks for clearing that up. i thought it might apply to both but knew only for sure or turbos. in that case you should see pretty good gains with the LT's

 

well w/ pacesetter lt's and radix on a 5.3, should i run the ORY or true duals?
