Dynomax Muffler

I have read a lot about putting on different mufflers and exhaust work. For my 2005 Pontiac Grand Prix (Non-Gt - single exhaust). Was going to do exhaust awhile ago, but stuff came up. I am looking at doing a Dynomax muffler with a dynomax glasspack inplace of the resonator.

What Dynomax muffler should I go with? I am looking at eaither the Thrush Turbo or the Super Turbo?

I dont want it to be a whole lot louder than stock, what it to have a better tone over stock.

Also what size of resonator inlet and outlet do I need? As well as muffler?

If you got video clips link me up!

Thanks!
 


So is the glasspack going to be 2.25 or 2" inlet and Im assuming its going to be 2" outlet for the glass pack as well?
 


anything before the y-bend (where you'd put the glasspack) is 2.25". anything after the y-bend (where you'd put the mufflers) is 2".
 
okay so I need a 2.25 inlet 2.00 outlet glass pack with a 2.00 inlet muffler? Now am I going to sound pretty close to stock with a bit of a deeper tone? I do a lot of driving with this so I have been doing a lot of research. I know for sure I will be doing a ZZP 3" Downpipe with highflow cat and replacing resonator with a glass pack. A buddy of mine just picked up an 05 GT with a 3" Downpipe and high flow cat and I like the sound of the duals, but want it a little deeper. Im having a hard time even trying to find a GT Rear facia, all they have exhaust wise is the same as ours but a y split correct or is that a single in dual out muffler?

no, you need a 2.25" to 2.25" glasspack and 2" to 2" muffler.

anytime you change the mufflers the car is going to get louder. i suggest you put in a glasspack and run the 3" downpipe with the stock mufflers to see if you like it. it does change the exhaust note a little.

all the GT/GTPs have a Y split to two mufflers.
