If I were to delete the muffler would I lose hp dew to loss of backpressure or would I gain hp dew to better flow? I plan on istalling in the very near future headers and ory. But right now I wanna know if it will lose or gain while stock. I know it will not sound good to some people but that's not the question.

Backpressure does not help make power, so no, removing the stock muffler won't hurt your power numbers.

I have not had one on my car in years. Long tubes, ORY. Its not a DD car. Just for a goof I dynoed through my Flowmaster and then Open. Open I ran 32RWHP more than through the Flowmaster. You might pick up some power depending on your muffler, but its gonna be loud. I never realized how loud it was until I rent for a ride on my R1 and had my wife follow me in the Camaro, I had her do a WOT Fly By past me, I was doing like 60. My ears were ringing for about 10min. And thats with a helmet on.

well, if you want to delete the muffler go for it, it all depends on your opinion. i doubt you'll pick up any more than 10 rwhp over a good cat-back. i ran one with LTs and ORY for about 6 months and hated it. yeah, it sounds cool at WOT from inside the cab, but standing a block away and hearing the car row through a few gears, it's downright obnoxious. also i drove from coast to coast and every time i pulled over for gas my ears felt numb. and forget about any and all conversation even under mild accelleration. a decent cat-back setup will eliminate the "clackety-clack" sound like your grandpa's old farm truck, and it will change the tone altogether. and it will also enable you to actually hear your radio on lower volumes. i would suggest going with a cutout if you really have to squeeze all the power you can out of your car. this is just my $.02 having run a straight piped car before. and by the way, a cat back like a rumbler or loudmouth won't be very restrictive since it's just a bullet on the I-pipe. but you won't be able to use a single cutout with one. most people say the bullet cat-backs are too loud on H/C cars, other people like it. once again, depends on your opinion. but i like the way they sound on bolt-on cars. TSP rumbler is cheap too!
