any one personally heard or own the spin-tech 9000s? i order em for the grand prix after hearing the 6000s on my bros 5.3 buick regal, i wanted something that is loud, nasty, and in your face. gotta say i think thats what i just bought. this will be interesting to see how they sound without the resonator. i have a feeling it will be bad *** but the phrase "for use with multiple cats" worried me a little

 

Id leave the resonator on and see how it sounds like that. then if you dont like it take it off but youll get the rasp if ya do

 

resonator has been recycled into something else by now ,

did nobody go for the big dawg? they souhttp://www.youtube.com/watch?v=ns21k-z2cJUnd bad *** on the trucks.

 

I have the Super Pro Street with a dynomax bullet right before it. It's ahight lol. When it was dumped under the car it was unbearable, now behind it ...could be louder...lol
