I really appreciate all of the feedback! I must admit that I'm shocked that there's no 2 people that does it the same way when it comes to headers and exhaust. However, there seems to be a consensus when it comes to Pypes and "shorty" headers. But from my research thus far, the "shorty" headers are primarily for short distance bursts or drag racing type usage.....so I'm a bit surprised that so many people opted for this application. I also shocked that more people are raving about Magnaflows. I heard that long tubes were a better option for your everyday/average type of usage. I also gathered from my research that the larger the headers the better because it allows for more airflow etc.... I also read that Hooker headers are garbage, but I also hear a lot of people saying they are sufficient. I guess what it boils down to is your personal plans and usage......and oh yea, your personal preference.
Brandon, just want to add my two cents here if I may.
I'd like to correct you on a couple of things, the length of headers has nothing to do with usage. It has to to with flow, horsepower and torque curves.
Traditionally, long tube or full length headers are better for making or spreading out the torque the engine makes throughout its power band. Shorter headers allow easier fitment, at the sacrifice of less than optimal flow and thereby shortening up the amount of torque made in the same RPM band.
Additionally, header primary tube size affects flow and power as well. Too large a primary tube size will kill flow, just as too small will restrict it.
You are correct in that exhaust (especially when it comes to sound), can very much be a personal preference thing.
Lastly, I wanted to say two things about the two manufacturers you listed, Magnaflow, and Hooker (and these are based on personal experience, and not opinion or conjecture):
I'm not sure where you heard or read that Hooker headers are garbage. They are actually of very high quality and fit and work like they're supposed to. I have two piece 1 7/8" primary into 3 1/2" collector Hookers on my 455, and I've never EVER had an issue with them in the 15+ years I've owned them. They flow and sound great, and have never leaked or blown out a gasket, even with their two piece design.
As far as Magnaflow mufflers are concerned, before this year I had never used them. When it came time to find a set of mufflers for Project Olds Cool, I took a chance and bought a set. I have to say, I'm more than a little disappointed with them. Sure, at full song at WOT, they sound great, but the rest of the time at part throttle, and at idle, they sound terrible. They have this buzzing sound that sounds like an exhaust leak or a broken baffle in them. But it's from both mufflers, so I know it's not a baffle. I've been under, over, and thru the connections, and there's definitely no leak. It's just the way they sound. Not a fan by any means, but to each their own. I know I'll be changing them out and selling them at the first opportunity once the seasons over.
Hope some of this gives you food for thought, and doesn't further complicate your decisions.
