Nissan 370Z Forum - View Single Post - Exhaust Finally Made It!

Here is an update from the weekend -

Installation-

Everything went into place better than stock. The clearance over the crossmember is substantial and doesn't come close to touching. the hangers and solid and hold the exhaust very firmly into its intended place. After driving around this weekend I have noticed the right exhaust tip is sitting a half inch higher than the left so a little adjustment will be necessary. I was in a rush to bolt it up as it was late and I was heading to a local meet.

Sound-

This is what took me completely for a spin. After watching all the youtube videos I was ready for this extremely aggressive tone at all rpms. I wiped down the exhaust for fingerprints and started it up.

Idle - Other than the usual growl we get at startup it quieted down to a tone quieter than stock!! It has this unique hum to it at idle but anyone near it wouldn't exactly be able to put their finger on what it is.

Revving - Revving the exhaust in neutral limits it to 5k rpm... the exhaust gives a sound out of nowhere! The best way I could describe it is having one of those vavletronic exhaust and flipping the switch... except the saclam does it based on exhaust volume and not some manual bypass valve. Revving to redline makes the exhaust sound like it is ready to jump the gates and is full of harmony and just enough popping on the way down to give it a race car sound.

Driving - Ill keep this simple... Anything at 25% throttle or less and this exhaust is quieter than stock, I repeat... I picked up my girlfriend with the windows up and drove off under low load and she asked what had happened and why I didn't put the exhaust on. With the windows up, the loudest noise in the cabin in the tires and rocks in the wells. As you press into the pedal, 50-75% throttle starts giving off a very sporty and exotic sound, much like a ferrari/m5 mix under normal acceleration... compliments each shift with a little pop for good measure. Anything at 100% throttle, and it just screams.

Something I would like to clarify is that the tone isn't RPM based... if you hold a 25% throttle acceleration all the way to redline it keeps the like stock sport sound. Only if you open up the throttle and bury the pedal does the exhaust tone rip out of the back. Another great thing is zero ZERO zero droning, to be honest... you can barely hear the exhaust at any point in the cabin except when passing under a bridge or through a tunnel. I had to drive behind/next to my car with someone else driving to actually get the full effect.

Butt Dyno -

I feel a nice jump in torque, I am not sure what the figures are but when I roll into the throttle at 3k I get a nice push back into the seat where as before it would just be more linear. The exhaust pulls well to redline and I don't feel any drop off based off the seat feel.

Overview -

This is my dream exhaust. I am so happy that I kept with my instinct and went with the Saclam. Workmanship and material is bar none, and the design is clearly unique. The resonators are very different after inspecting them on the interior, I won't disclose the design but it is not a typical perforated or louvered core...

I personally like loud exhausts, so I am going to experiment and install a test pipe to see how it changes. If the result is too offensive I will move to a HFC, really in search of the extra power and little less restriction of noise. This will be paired up with the Maxim Works exhaust manifold which should be on the way already, that will complete my exhaust at which point I will get on my local dyno to get some numbers up for you guys.

Time to decide on an intake, as I haven't found a favorite as of yet.

I will be posting videos tonight, so check the thread in the late hours... at which point I will answer any other questions.

Thanks!
