catback comparison
Mean sound without being overbearing. skares the **** out of others if you WOT next to them
Hooker has a well designed chamber muffler and good back pressure readings.

Until next weekend! that is when i will install my Pacesetter Lt's & ORY!
Can't wait!!!! Will be selling my LGM Y pipe soon.
I asked a while back about the quietest cat back since I want an old man's performance exhaust. The general consensus was SLP dual/dual, with the SLP 2OTL second place. Since SLP had recently announced that the dual/dual now had a more agressive sound, I went with the 2OTL. Just put it on yesterday. Trust me, contrary to some of the posts, it is NOT as quiet as my stock muffler. It isn't bad - I can still hear the radio on the freeway - but my wife, who grew up with a loud Road Runner next door and made me promise that my mods would not make my Z28 loud, swore at me when I fired it up to leave for work this morning

I see posts where guys talk about how great the sound is with a loudmouth or open Y pipe. I can't imagine how you could even think in the car! I have driven my share of cars with open headers, and even had cutouts when I was a kid, so I do know what open cutouts or open headers sound like!
Bottom line? Sound is a personal choice and hard to describe accurately. It is even hard to describe with sound clips as there is no common standard. Reporting DBs 10 ft benind would be good, but who has a meter in their tool kit?
The SLP 2OTL is definately louder than stock, but, IMHO, pretty quiet for a straight through design. More quiet than the glass packs we used to use, even when they were new. Not as quiet as the Corvair Turbo mufflers we used to run on our duals. That is the best I can do to quanify the sound.
It would be cool if we could change to any sound we want at the flip of a switch.I have an SLP LM w/cats and get compliments all the time.I've heard the GMMG with and without headers,i've heard Borla w/headers,i've heard SLP LM w/headers...OMG.Now i want to hear the Hooker and the Magnaflow catback..........in person
