I have the GN1 3" exhaust with the mufflers that come with it. I no longer mind driving my GN the way it sounds now. This is the best exhaust sound I've ever heard from a GN. No drone and it's a deep musclecar sound. FYI - This system is a Chinese knockoff of some other exhaust system no longer available.

There is only one muffler that IS the GN sound: Pitbulls from the old ATR.
Anyone who has them will testify to this fact.

I know I will get flamed for this but
 I like the Flowmaster 40s they sound real nice , I know they hurt tons of HP ? I have Magnaflows on mine but still like the sound of Flowmasters better , I have never heard the sound of Pitbulls anything on youtube?

I have to agree about the ATR Pitbull mufflers sounding great on a GN. They give the car a unique sound that is all it's own. However if you don't want to be noticed while driving down the street you had better forget about the ATR Pitbull mufflers.

I love the Pypes RacePros on my car. They sound great and have no drone. I used to have an SLP muffler, side outlet exhaust on my car, and it was the best sound from any gn I have ever heard, but it was the worst drone, and muffler was smashed from previous owner so it had to go.

I doubt ATR actually made the Pitbull mufflers. Some muffler company had to me making them for ATR.

Here's my car when it had the old Flowmasters on it:
http://www.youtube.com/watch?v=oKwDLRJXkuo Here it is with a straight shot 3 inch single pipe and Ultraflow muffler: http://www.youtube.com/watch?v=w5_a5Bs4fXc You be the judge.... I can say it definitely has more top end power with the 3 inch set up....

I like no mufflers, sounds and performs great.
There isn't a muffler that flows better than a Hooker Max Flow, it literally flows like a straight pipe which is great for any FI car. LS1TECH

Sounds like most people like what they have.
I use a 3in $25 summit muffler off of a straight pipe and with a turndown, its quiet to me!

First thing I noticed was the sound. They sound like crap. Specially WOT.  According to the seat dyno, the car did not run any different just sounded worse. I was soon back at the speed shop picking up some more flowmasters. They sound the best hands down. The car runs just as strong if not stronger with the flowmasters.Be glad to take anyone for a ride. You too can become a believer. Right John? LOL!

My 2 1/2" Pit Bulls droned, but sounded great. I have added the Ultraflow crossflow & got rid of the drone & it is quieter. Pit Bulls & Ultraflow are straight through & almost no performance difference compared to open dump.
