Completely functional and not noticeable at all while installed on car. $1100.00 or Best Offer. Will ship at buyers expense. Paypal. PM if interested. Bay Area, Cali.

I live in SGV, Cali. Wondering how loud would this be compare to a standard muffler delete?

Any noticeable difference in tone?

Well the sound will change depending on other parts attached, but with stock headers and cats, the Fast Intentions Cat-Back is louder than stock, but not as loud as a muffler delete. Using the FI Catback also creates a deep, smooth VQ tone, versus a more aggressive, popping tone. Idle is very quiet, louder but close to stock. In-cabin resonance is about mid-level at highest. Deep hum at certain rpms/speeds, but overall pretty bareable.

I have moved on to the NISMO Catback exhaust due to pending project changes.
