**STICKY WORTHY** GMMG Exhaust.. How To Eliminate Rasp * Lots of Vids and Pics*

Just some info I want to add regarding this thread. The title may be a little misleading depending on what the rest of your mods are. My friend has a GMMG exhaust. His car is a h/c/i car running AFR heads, MS3 cam and fast102. He dynoed at 468rwhp on a dynojet. He added the powerstick and it did very little to reduce rasp. I cannot tell any improvement or difference in sound quality.
The powerstick may help for bolt on or slightly modified cars. On cars making more serious power, the powerstick doesn't seem to help much for reducing rasp.

I PM Torchd asking him a couple questions, but want to get others' input as well.
My setup is 1 7/8" TSP, TSP 3" ORY, and Magnaflow 3" Catback. Also have dual DMH cutouts in the bends of the y pipe. Will adding a powerstick help? And also how is it going to sound with the powerstick AFTER the cutouts, with the cutouts open? Another question, will this reduce noise even further? Because magnaflow is already really quiet and dont want to lose all my noise!
Thanks

Want to get rid of rasp get rid of the y pipe,the cats help the shitty design of a y,the gmmg sound great and even after having duals for awhile i still love the sound off a gmmg,but if ya want to cut down on rasp/frequency high flow cats help,also a very good y merge,but imo duals will always out sound a y pipe

I have Kooks LTs, the GMMG, but I have the catted y-pipe... it tones it down quite a bit from what I hear in this thread. Probably a little raspier than some of the people in the thread seem to want, but I personally love how it sounds.
This is what my exhaust sounds like..

I am with ya bro! I spoke to Eric @ Classic Chamberd Exhaust he told me that the Powerstick will NOT make it any quieter, it just changes the tone. I am thinking that a Cobrapac or any bullet type glass pac in the I pipe with cats and two more 12" cobrapacs in the tail pipes will be as quiet as you can get while still mataining flow.

COBRAPACK MUFFLERS – 3” OD Flowpath (*Over 450 HP)
(NO PACKING - More Aggressive Sound)
COBRAPACK MUFFLERS – 3” OD Flowpath (*Over 450 HP)
(WITH PACKING - Better Noise Reduction)
Or at least very misleading.
Also, why would you go with (2) 12" cobrapacs? Why not just 1 longer one?
