When ever i first took off my muffler my car was loud and recently ive noticed a change my car doesnt seem as loud as it did i have my header on and my cat back and thats it my muffler is gone and before around 5k it would get real loud now it just sounds like my muffler before but just louder before when it was off it sounded different and i liked it but now it seems the same just louder what is this prob and also can i damage my car because i was goin to order a test pipe and just have like straight pipe and i dont want no problems?
If you get a test pipe and no muffler… oo man… its way TOOO loud… I need like ear plugs going under over passes… I think its louder then a straight header.
OMG I cant understand what your wrote dude…try using some periods. The only thing i figured out is that you car is loud with no muffler? No, a straight-pipe will not damage your car but it will make it a bit louder.

ALL im saying is i have a 90LS i had a borsal exhaust on there and when i took it off it was really loud and sounded weird but now which is like 2wks later it doesnt seem like it did when i first took it off and it sounds like like it did with the muffler just louder before it mound a weird noise what happened to it and also when i get my testpipe dont i have to worry about back pressure or something im not sure???
shot in the dark…
you still have a cat? check it, it may have collapsed, that would make your car quieter. if it was collapsed, it would feel like the higher in rpms, the slower the car will accelerate.
