Fast Intentions exhaust is here!

I already built a prototype 3" CBE for Sebastian's 370Z at SpecialtyZ. It came out great and is quieter than the 2.5" version. This is due to the turbos acting like primary mufflers. Comparing apples to apples turbo cars are usually quieter than their N/A counterpart.

Things have slightly changed since last week though. This may be a project that Fast Intentions will venture into solely on our own!

Time will be the test. I hope to have the first report for you all within a few months.

It will tank your low end torque and mid range power. It may pick up minimal horsepower in the very high end of the RPM range! However the trade off is not worth it.

That pretty much should sum it up...

Thanks, Tony

Now due to our design we have never sacrificed low end torque or mid range power on ANY of our exhaust systems.
