while growing up i have always been around older muscle cars(my dad and i built a 67 chevelle that has 730 hp to the flywheel). All the older muscle car guys always say flowmasters is the way to go. But what catback gives our cars the most rwhp? or do they not really make a difference? I was thinking about switching from my generic borlas( on the car when i got it) and going with sss adrenalines but i do not want to decrease my rwhp do catback really make a difference?

You will get the most power out of 2.5" mandrel bent ones with straight-through mufflers...they are all pretty much the same performance wise

mrt how do you like the terminators? And i have a O/R h pipe. Do you think it will be too loud with a O/R h?

Ir really makes no difference. Maybe like 2 hp between different cat backs.

Nice choice on the SSS Terminators btw. At least it will sound fast.
