I've done Gundo a few months ago. I like the sound.

I actually found it a bit loud in the beginning but now I want to go louder.

What would you recommend as the next step. High flow cats? Resonator bypass?

What's the best bang for the buck?


P.s.: A friend of mine has a few full exhausts that I could put on but I would like to do this step by step. I'll swap my exhaust if and when I get bored.

 

Go with cats.... I am getting xpipe cat from fabspeed.. Look for videos on YouTube but I've always found that videos especially sound on video does not don't justice

 

+1 on the x-pipe 200 cell cats from Fabspeed. I have them with the PSE and it sounds amazing!

 

Does your "friend" have a set of headers for sell?

 

On my 2009 DFI I'm running Cargraphic side mufflers and last week added the Sharwerks X pipes - sounds like the ole school...absolutely fantastic, no longer the DFI wimp sound

 

I am having a 2" Gundo being done as we speak and will also have some HJS 200 cell sport cats put on later this month. I hope that does the trick on my 996

 

muffler bypass pipes. $300 from fabspeed.

 

I installed a set of sport cats on my 996 and I was really pleased with the sound.

 

AWE 200 cell cats.

 

+1 on the AWE 200 cell sport cats.
I have the Gundo hack with the AWE cats, and it's naaasty!

 

Nasty where it wakes up the town at idle? Or nasty when your at WOT

 

Nasty not by sound volume, but by tone. The tone, when cruising slow around town, is clearly serious. Without being overly loud, it's obvious that there's power there. It is definitely not raspy, and there is zero cabin drone.

It's a low and deep exotic burble at low sped. As RPM's rise, it turns into a growl, then a howl, then a vicious scream at high RPM and WOT.

Here is a video of when I had this combo with the SC. The SC gave it a higher pitch whistle at times, but this is still pretty much how it sounds..

I've got Cargraphic Loud mufflers and NHP 200 cell sport cats. No drone and pretty loud at WOT. I'll be selling the system if you're interested.

 

How much for Cats?

@White Rock: He's droping by later today. I can ask him if you're interested.

 

I was in the same boat as OP. Did Gundo first, wasn't loud enough, so added EVOM airbox, X51 headers and AWE cats in one shot. Loved that combo! Felt it was civilized enough at low RPM but crescendo'd linearly to 5500 revs, where it boomed perfectly. Here is a video of that setup on the track:
