Have had three of these choices, the RSRs, the Stage Is and now Stage IIIs. The RSRs are a nice upgrade but produced a drone between 2500 and 3000 that bothered me a lot and I sent them back. Next was the Stage Is and these were terrifice, no drone at all and a nice deep sound. Eventually though I wanted more, that sound is addictive. Hard choice between the Stage IIs vs. IIIs. Sometimes feel the IIIs are just a tad too loud and think the IIs might have been a better choice for me. But, I've gotten used to them over the past few months and now think I've made the right choice. Funny thing is, since putting on the LWF, the little bit of drone I was getting seems to have diminished. Mark and Darin are the best, you can't go wrong with either of their mufflers.

 

In case nobody's mentioned it, I would recommend Fisters . Fantastic product and great guys to deal with. 2s if you wish to be quite civil, 3s if you want a more aggressive sound.

 

Has anyone tried cat bypass pipes with their stock mufflers?

What does it sound like?

 

I agree since installing the LWF the stage IIIs sound even better.

 

I thought this was a really good video... I think he's a member on here.

says the guy that weld exhaust systems as his day job.........................

 

LOL @ "993 Performance Exhaust"

There ain't no such thing. 993 noise-enhancing exhaust yes, but performance no.

 

Bah, losing 40 lbs is a performance gain!

That it sounds much better is just a "happy".

I have the Fabspeed RSR Header and Muffler set up, and am very happy with that. Sound is great, especially at high rpm. I have also seen the combination of Dansk headers (w/ or w/o heat), Fabspeed X-pipe and standard mufflers. The sound of that set up is amazing, like a GT3 on high rpm.

 

I have Fabspeed cat bypass and Supercups -- but wouldn't even think of driving it on the street. Sounds awesome at the track. All the pops and gurgles on decel when pitting in make you want to go right back out.

 

Is it way louder the YT video posted above? post #18
