one shop around where i live will do it, but they make you pay cash and no receipt, so there is no record of the job being done.

For sure sure the abovementioned mods would work, but I wasn't referencing changing parts out that result in better intake tract, higher compression, legit cam etc. I was referencing the common theme with a lot of guys in that the belief of taking off the cat, or putting on a K&N will awake an 8 second car.
Oh no. with that alone. no. your right. You will get a 25 horse power increase with a K&N system and no cats. I mean to get the sound and tone definition of aggression you will have to put forth a flowmaster, magnaflow, borla, etc. muffler with y-pipe and headers to any V8. That is to get that perfect rumble out of even a 305 or 289, 350, whatever with 8 cylinders. An 8 second car out of the heavy F-body takes money. The stock 305 was running 14 and 15's outta the factory. Hell, the new 2010 ss camaro is running low 11's in the 1/4!!!
