I would recommend a Motordyne TDX V2. I just installed mine last week with ART pipes and MY F**KING GOD.. It is the most amazing sound ever! I haven't been driving super aggressive, but it has been turning heads everywhere! But if you were looking to pass inspection, I'd recommend keeping a eye out for a Motordyne TDX V1 exhaust. This version allows you to run Motordyne's HFC module. But if you are going to keep the OEM cats on, definitely go with the TDX V2. I waited for almost 2 years to be able to afford this system, and it was so worth it.. I could not be happier with it. I have always loved driving my car, its my stress relief. But now with the new exhaust setup, I cannot wait to wake up to drive it everyday. The note is absolutely intoxicating. Just my $.04 lol.

 

Maybe, turbos slightly muffle the sound. But you can't get much louder then straight pipes with a dual 3" setup. Whats the diameter of your exhaust? Dual/single?

 

HO MY LORD

 

Dual 3"

 

it's not just about how loud, it's also about how good it sounds too

 

I am straight piped all the way. no cats. 2.5in. right at about 3krpms it gets rediculously loud.

what difference do you think 3in all the way back would do?

 

Surprised you haven't seen that thread before, car's a beast. I got to drive it last year and all I can say is O My God!!

 

I really love his post....^....someone that enjoys driving his G as much as I do!

Yeah I mostly stick to coupe or local section of the forum... Not that I don't love your guys' sedans just the same

 

I think i was one of first couple people with this setup, IT IS LOUD. I cannot think of any other setup that is louder than this. I had to switched to HKS/ART setup to reduce the sound. Driving in LA is no joke with the 5-0.

If you do not care about performance gains, remove the muffler. That will be loud enough. I don't recommend anyone going louder then that....You'd probably get pulled over. But if you want to, I guess you could remove the resonator, but when I did that it sounded like a Nascar straight pipe racing car lol.

anyways, heres a vid of my g without a muffler
its much louder in person

Here is an older video of my G, it looks a lot different now than what you see in the video...but my exhaust setup remains the same

 

That is probably bat **** crazy loud. I wish I could hear it in person!

 

Ive been told by a ton of VQ owners its the loudest they have heard. I have yet to hear louder myself

 

I'm pretty sure the V1 would be louder then the V2 w. Art's. either way their both mean sounding exhaust...even the HKS is impressive.
