Hey guys,
I have a Tubi Exhaust system which does sound really good but I am looking for more. Does anyone know what type of sound would be had if the Gundo hack was done to an aftermarket exhaust? I was riding next to a Ferrari yesterday and the sound was incredible, I want that sound!
Thank you in advance!
Googled and I like how it sounds. Wondering how it will sound accompanied by the Tubi considering all I can find is them with a stock exhaust. It could be better, but it could be worse, should I go back to factory first?
I have mine Gundo hacked and it sounds awesome. Not too loud and no drone. Only gets loud when I�m hard on the gas. Do you have a sound clip of your Tubi system?
Here are two videos of a 996.2
Kline headers and 200 cell X pipe and Tubi Style mufflers
This motor does have mods.
Don't hach your Tubi mufflers
First video, it is bouncing of 5k launch control rev limiter, revs are not going over 5k

i second the do not hack up your Tubis, if you dont already have high flo cats get those, you can also add Tubi headers, i have Tubi headers, Fabspeed 200 cell cats and Tubi mufflers on my '02 C4S and the sound is absolutely amazing
So here it is, I have no idea why it looks like it was filmed on a 1978 camcorder. It was taken with an iPhone 8plus lol Oh and it was a freezing rainy day, she doesn't always smoke like that its the cold weather.

i did the fister mufflers to my 03 and soon wanted a little more sound. I went with a cat delete X-pipe the day after i got it smogged. the sound is awesome after 3500 rpm.
Scott here at Fabspeed, consider a 200 cell High flow catalytic converter. Our system is a direct bolt on product, cut some weight, add exhaust note, and performance gains! Consider your factory cats are at the youngest 14 years old! So replacing them will only help the engine breath more efficiently! Take a peek at the product and feel free to reach out for forum pricing!

Here's a video of my muffler bypass. Two weeks ago a guy in a Ferrari F40 pulled up next to me and asked what exhaust I had on my car. It may be the exotic sound you want, but it's definitely not for everyone. The weight savings is a huge plus too.

I have muffler bypass on stock cats but I don't daily drive the car, or street drive it much at all. I can't imagine it would be tolerable with 200 cell cats but it's awesome with stock cats. Low-range torque is lost, but high RPM hp is gained and a LOT of weight is saved.
Bypass with a 200 cell x-pipe got two notable comments at a track day; "glorious!", and "is that a flat six?!". It's rowdy for the street, but sounds amazing at full tilt.
Yes stock cats are still on the car.
IMO it's not that loud after driving it pretty much daily for 3 years like this. I did a back to back with the stock mufflers and I can never go back. Hearing the car rev makes it so much easier to drive. Just have to watch out for cops in Los Angeles. There is a way to drive it quiet enough to where they won't notice it.
Thanks Bill. Sad thing is I just took this vid Thursday. Today this area is all devastated by the Woolsey Fire. This was taken on Mulholland Dr and Kanan Rd.
Any decent exhaust shop should be able to do it mine cost me $200 cash ,,,,, just remove the mufflers and show them images of the merge pipe added ,,,,there are many online photo,s ......seriously the best valve for money exhaust mod and makes the car sound like it should have from factory ...no drone ,good rumble at idle and a really good flat six howl when you get on the car hard with some small pops and burbles when you jump of it ...
top image is a Fister Mod with 1 inch and 3/4 merge pipe ,,,you can go as large as 2.5 inch dia pipe ,,,I went 1 inch 3/4 personal choice didnt want it to loud ..
many you tube videos and many threads on this site about this simple mod ....

I just saw on E-Bay a sport exhaust with electronic bypass valves for $1300 with free shipping, from England. The manufacturer is Topgear and its being sold by Pure Performance Parts.....It seems to me that's a really low price compared to everything else I've seen...anyone have any experience with their products.
I have their Big Bore High Flow Catted X-Pipe. Decent quality, sounds great with Fabspeed Maxflows. Fitment was a little challenge due to the big bore piping, if I did it again I would get factory size piping. I considered removing the supercups and trying that exhaust. I would think a factory PSE Switch would work perfectly and look great. If you do this and like the results, Let me know. I'm Very Interested.
I'm trying to understand the difference in sound and design between PSE (which I have), Gundo and Fister. I've been searching but no direct comparisons. Anyone have a explanation or know of a link to one?
