I had bypasses for a while and there was a definite drone around 3k rpm. I did not like that.
Now have Fisters and love the compromise with a lot more sound than stock, but no droning

I have fabspeed muffler bypasses and no drone....lucky i guess

No HTwo O

That's because we're used to it, I guess.

Thanks Tony! How are you liking the new turbo? That power is very addicting

DALLWA

Car is incredible, and really enjoying that power more second time around.

Drive the 993TT in a parking garage last night, and the sounds were intoxicating.
You have mastered your craft, its gets better each time.

When I bought the car, the PO had initially put FS Supercups on, then decided they were too loud, asked for the stock cans back but they had already been recycled. So FS built a pair of "stock-like" cans for him, which were easily as quiet or quieter than stock. In other words, too quiet for me.
So I went back to FS and had them put on the catback bypasses. Plenty loud! But there was a definite drone at idle, also a bit monotonic for my liking (all baritone, no tenor), and to be honest just a bit on the loud side for my otherwise quiet neighborhood.
So I sent the cans to Darin and now they are perfect for me. Right in-between volume-wise, no drone, nice basso growl under acceleration, burbles pleasantly on decel, with a few discrete pops when blipping the throttle at a standstill.
Darin was a pleasure to do business with: quick to provide info on the front end, did the work promptly, with nice fit and finish, and sent the modded cans back promptly and well-packed for shipping.
To each their own, I guess, when it comes to what you want your car to sound like, but Fister gets my vote.

Knight, we'll have to get together to compare systems. I have Fabspeed bypasses - a bit of drone top gear at 70-80 mph which tends to make me gear down after a while. It's ok out in the countryside but probably going to be a bit much when we relocate to Vancouver and twiddling around town most of time. I might put Fisters on next yr.
Cheers

Hi Mark - For sure, whenever your in Vancouver just let me know. Or by chance are you coming to Mike J's bbq 18th?

Mike J

Mark wont make it - but i have been in both of your cars, and the bypasses are a bit too much for me. As mark says, he is moving down to vancouver and he will be triggering car alarms all over the place...

I sound like I'm driving an electric car compared to all the Lambo's and Ferraris in Vanc though
Broke my ankle 2 dd ago motorbiking Iceland so no Porsche for me until cast comes off - hopefully Sept - catch you then, Knight.

I swear these things are getting louder every day. Love it!

Tokyo Joe

Thanks for posting the pre/post video, very helpful. I've been considering such a modification for some time but could never sample a before and after scenario.

I'm not concerned about their impact on peformance but do they get louder over time?

DALLWA

Glad to help, best mod for your money.

I've come to the conclusion they don't get louder over time, but much louder when cold. I find myself starting my car just to hear it.

Knight

Totally correct about the start up.

I've had mine in since Jan and no changes volume.
