Fabspeed Muffler Bypass Pipe

[GranburyChuck]

Has anyone tried the Fabspeed Muffler Bypass Pipe? I have seen postings about the cat bypass but not the muffler bypass.

Anyone?

My friend (he is 20 years old) put the muffler bypass on his 997 S. The car is very LOUD. It sound good if you're 20 but is too much for most people. He feels he has lost some low end torque but likes it overall.

You can go to the Fabspeed website and listen to a soundbite with the muffler bypass.

You do have a sustantial weight savings without the mufflers. If you do decide to buy them you can switch back to the mufflers very easily. Just takes a few minutes.

If you looking for performance I doubt you will be impressed.

You may find the car to be obnoxious.

If I were you I would go for the mufflers (Tubi, Fabspeed, whatever.) The mufflers save you some weight and have a very nice sound when you get on it.

Hope this helps.

When you reduce back pressure in exhaust system for sure you loose low end torque but you gain a little bit on top end. Many years ago I have raced karts- Yamaha 100cc class. To gain low end torque you would install longer "flexpipe". If top speed was the goal shorter pipe was the solution. Provided that your gearing was setup to optimum you would do fine tuning with "flexpipe". Same principle here.
