SRT and Borla here. Really like the sound but I think I am going to try out the Blitz exhaust.

GS42NV

Stock intake for now (until I can pick up a black SAFC2 from somewhere).

But i'm running magnaflow mufflers, with custom piping (2.25") from the first resonator (almost an x-pipe). I cut out the individual resonators on each pipe leading to the mufflers, and replaced it with the larger piping.

The sound is great. No extra noise at idle. Under light throttle it has a lil throaty groan to it. Under WOT it screams. No droning at all. Plus, this cost me about half of what most other retail exhausts go far. Would definently consider this in your next purchase. Total cost was about $440. About $220 for the mufflers and tips, and another $220 for the install (which im sure you can probably get for cheaper)

K&N drop-in & L-Tuned Exhaust. Surprised what a diff the drop-in made. Maybe someday I'll get a real intake? I hope.

SRT with L-Tuned. Every time I go to Carson Toyota to pick up a part I ordered I end up buying something else to!!!!!

SRT Intake, S&S Headers, custom stainless 2.25" mid-pipe/Magnaflow X-pipe straight into Carson Tuned 'Cat-Back' resonators, mufflers and Magnaflow 5" rolled tips. This combination makes a significant increase in power and gives a deep, throaty sound.

RMM Intake + HKS mufflers. The sound is not too loud at idle.

For me its the stock intake and RMM mufflers. Not too loud at idle and sounds great under wot. I had the RMM intake on my GS300 and it killed my response off the line so I went with a 3.76 lsd on my 430...great response off the line

I have the SRT and the Tanabe Medallion Touring exhaust. A little loud for my tastes when cruising with windows up, but absolutely love it with windows down, or if I'm racing around on some mountain roads. My ears are sensitive though (I like the quiet)...EVERYbody else that has been in my car since I installed the exhaust loves it. It can be intoxicating, I have to admit, especially at WOT...deep and throaty.

And I have to say, the Medallion Touring is sexy as he11...I love the visible stainless steel canisters and the oversized tips.
