Exhaust is too loud
 
Well guys, its the beginning of the season, and since i just got my car last September I am looking to take it to its first track and autoX days this year. When I first got the car I was less than impressed with the exhaust note. Too quiet. So I installed short tails. But now, i need something more quiet to be allowed on the track. What are you guys running exhaust wise? I need to be less than 95db. I'd really rather not lose completely my exhuast note i have now. But I dont want to spend the cash for valvetronic, as I still need an oil cooler and such. Any reccomendations? Thanks!

Go ahead and get your order in for Fast Intentions.

Thanks guys. Is that confirmed to be quiet enough? I just dont want to still be too loud after dropping the cash and have to go about using a decibel devil or something as well.

Talk to Tony at FI. I am not sure exactly what the noise level is but it is quiet enough I didn't get any complaints at AMP or Barber.

At 50' (SCCA autox rules) my car with FI CBE and LTH was ~93-94 dB.

None. He's running straight pipes from the headers back and probably 40+ dbs over the limit lol

Yes, 50ft away is going to be about the norm. For instance AMP is 98db at 50ft.

You better worry more about if they even let you on the track with those RE71 in 205's on the back!

If you want to go the cheaper route do what I did. Custom xpipe, true dual, 18" resonators with Top Speed axle backs. Good low rumble and I had no complaints at all at my first autox event. Every other Z owner that has heard it really likes the tone.
