Can't decide on which to get and no one around me has ether!!

I have 40 Flowmasters right now and sound decent but I hear good things on spintech..

How much louder are the 9000 vs the 6000 ??

I have a
5.7 vortec with whipple
CAM
LT Headers
X-Pipe
2.5 true duals

See i've heard people say the 6000 gives a nice tone, just curious if the 9000 is really that much louder. Hate to get the 6000 and be like well damn wish I woulda went with the 9000 or the other way around! lol

My brother had the 9000 on his truck with headers and offroad Y and it was fairly loud, but sounded pretty good. The 6000 sound pretty nice as well, and its a bit quieter. Both are WAY raspy at WOT

I got the loud one and it was too loud for me. Added a Straight flow through Magnaflow in front of it to quiet it down...

I had the Spintech 8000 with LT headers and it was very loud.

I just ordered the 9000.. I was hoping they wouldn't be raspy!! Crap!! I sure hope they aint that bad

I've got the 9000s on my 02 Sierra Denali. I've got 10.9:1 compression, long tubes, x pipe, no cats and dual 9000s. 3" the whole way. While it's pretty loud, it's by no means unbearable.

What was the end result, was it raspy?
