We just installed our Fabspeed 2ndary Catbypass Pipes, X-Pipe Center Resonator bypass and Stebro Race Muffler bypass Pipes on a 2003 Maserati GT. He wasn’t sure on what it was going to sound like but I told him it was going to be very loud since there was going to be no muffler son the car but that’s what he was going for. The installation took about 3 hours to do all three items and bolted right up like OEM with a snug fit.

The big power gains on this car, are eliminating the 2ndary 500 cell catalytic converters because of their size and restrictive design. Check the pictures below of the unbelievable factory design versus ours, I can’t believe they designed the exhaust this way. The X Pipe helps improve the aggressive sound and also increase a little more power. This car was so aggressive outside but with the windows up, there was no Drone or resonance with this bypass setup which was incredible. The customer was happy to save 26.55 Lbs. off the car and give it a really distinctive sound.

I have to tell you it sounds aggressive and really makes a nice power improvement but it will wake up the neighbors. The customer loves the sound and power increase and thats what matters. PM or Email me if you have any questions.

Thanks,

Sounds very nice, great work!

 

I recently had the Fabspeed secondary cat bypass, X-pipe and rear boxes installed on my 2004 Coupe GT and I couldn't be happier. The sound is strong but no buzz or drone and the responsiveness is amazing. The car is really crisp on the throttle. The quality of the pipe work is simply beautiful! It's a shame to hide them under the car.

 

Thanks for the great feedback guys. It is a great upgrade for these cars. Enjoy it.
Thanks

 

Awesome and to TS
