Just ordered my GMMG catback Was debating the Rumbler, GMMG, B&B and Mufflex with Spintechs. Was so close to ordering the B&B from Speed Inc but they were out. The price was great at $699 but N/A.
Getting Kooks with a catted Y so should be a nice set up. Currently have a cutout on the stock factory exhaust so hoping a decent improvment is made. Love the sound of the cutout with stock manifolds but needed something better. We'll see how I like it.
Been wanting it for 2 years, finally got it. Hope it was worth it!

Was debating on gmmg and b&b way back when. They only thing I didn't like about the gmmg was a bit of drone and cabin noise where the b&b was quieter. If I recal too the gmmg was a little quieter at idle until you stepped on the gas. WOt they both scream equally as nice

Yeah, the vids probably don't. Hard to tell.
It was a dead heat for both B&B and GMMG but like I said, Speed didn't have it and so GMMG it was.
We'll see if there is any time reduction at the track. Best so far with just the cutout is a 13.13@107.99mph. So I was stock save for the cutout. With the cutout closed I went 13.18 so it made no differance. Kinda want to hit a 13.0 before going with LT's and drag radials we'll see what happens. Damn automatic holding me back. LoL
I am lucky...been waiting for 2 years to get the GMMG or a single mod for my T/A, waited long enough.

Here is a clip of me racing at the UTI drags in Nov. Not my best showing but oh well.
Hope it sounds better than what the cutout does. I like the way my cutout sounds!

Well put it on today. Liked it a lot. Deff not as loud as my cutout was but that's why I left the cutout attached 
I like the sound at WOT, muscle sounding but so far not very loud like I was expecting. So overall very nice.

When I put it on my stock manifolds/cats, it sounded good and it did get louder after a little while. Same thing when I added headers. I had it on the stock manifolds for a year, first drive after the headers went on I didn't like the sound. I don't know if it was something with the car or something with my ear. It did work itself out and sounded great on all accounts. Catback only, LTs and catback and H/C.

Cool...I guess I was expecting it to be louder. I am very happy with the tone though. I finished it late so didn't get a chance to video it but I will tomorrow. My best friend was laughing because he said I spent $700 on the exhaust when my cutout was louder. LoL. Then again he has QTP's w/dual ele cutouts, Moser 4.10's and a LM1...so...
Sorry man but that was just gay. 
ya fish.
