Fabspeed GT3 Style Muffler Bypass

Recommended Posts

:help: I'm looking for some DIY instructions on this surgery to my 03 C2. It looks to be quite simple and bolt on, but I'll be doing this myself and it would make me feel a bit better about the job if I had some instructions to fall back on. :wrench:


Thanks in advance!


Hey Loren - missed you on the drive last weekend!! :drive:

Just follow the PSE removal instructions here. When you have the mufflers off you will attach the straight pipes directly to the cats.

I hope you don't get the flat spot (that some folks have seen) in the mid-range of your hp and torque curve. Let me know if you have questions

Yeah, it sounded great. Maybe I can make the next drive. I've been busy looking for a job...

Robyn- I really do not think you will like those bypass pipes... You will end up removing them in under a week. I know of a few guys that changed to them and them went back to the PSE. WAY TO LOUD. Just imagine the nasty loudness of a honda with a coffee can exhaust and multiply it by 5. I would really save your money. These were not for everyday driving. Only Turbos can get away with them because the turbos will muffle the noise.

But if you like making your neighbors mad or want to draw even more attention to your Speed Yellow car then get it. Every rice burner car will want to race you even more.

You been warned :)

Hi Robyn,

This mod is very easy to perform so just go ahead and do it.

At the end of the day - If it is not your cup of tea, it is very simple to return to your current setup with no side effects (maybe some ringing in your ears though :D )

If you do not give it a try, you will never really know what it sounds like unless you catch another vehicle with the bypass pipes.

I was contemplating the same thought with my new vehicle (Nov 14 Delivery - SY C2) and just to try it out I will get a local exhaust fabricator to make up some homebrew pipes just to give it a try before purchasing the real items.
