If money is issue Gut the Kitty box out the sound to me is just some thing you get used to but i have nothing to compare it to so it does sound differant if you need better pix let me know i have more that i did not post. and i all so did not know what the differance is with or with out the PCiii i put it on and have loved the lower speed control in parking lots (NO JUMPYNESS) and my vtec open up is now at 6700 rpm's not 6000 (I think that is in the map i have on it) I M126-003 Staintune slip-on exhaust with or without baffles, Stock or aftermarket air filter (this is the one Dyno said for me to use till my Staintune come in the mail. PCiii Recomended My PCiii came with the o2's. I did not ask for them. they were in packaged shipped quick, it was about 287.00 with shipping and tax (estimated)
I just gutted my cats and I think the sound is great. I have a Leo Vince exhaust and have the baffles removed...It sounds just a little louder but there is no "hollow can" noise. I think when you get your exhaust you'll be very pleased with the sound.
