but,all the magazine gurus,hype,and crap,is all with all the carb they can run,with maximum jetting,and peak rpm horsepower,blah,blah,blah. not at driving around town and street crusing,where,you will not notice a lick of difference between cleaned up HP manifolds and cheapie headers. and then factor in the future leaks,tight fit,etc. not worth it. really. and the difference in 2 1/4 over 2 1/2. on your car,with the weight and all things considered,2 1/4 will more than suffice. i don't know how many people you see on this board,and alot of other places,that are barely making 400hp and actually believe they "need" 2 1/2 or 3" mandrel bent exhaust on their cars.lolol really. well,i guess they might think that if they listen to all that "magazine,perfect world,on paper,westech dyno proven" bullcrap. i read that stuff for what it is.......good reading. then i go with what works in the real world,on the street,etc.
