SmokeyDP,
Ditch the shorties!
These things were designed for people who don’t have access to a custom exhaust facility or don’t have the ability or know how to do it themselves. Shorties are an easy bolt-on that have no advantage over the stock headers due to the restriction at the connection to the H-pipe. If they made shorties that mated to the exhaust pipes in the same way long tube headers connect (collector), they would provide better flow over the stock set-up but then they wouldn’t be an easy bolt-on.
I’ve went that route with the shorties, both equal and unequal; they were a huge disappointment! If you plan on better heads or cam swap in the future, your level of disappointment will be even greater with the shorties.
If you want your exhaust system to breath, go with full length long tube headers. Your engine will sound better but best of all, it’ll run better too...
