i ordered a zpi stage 0 with all the fixins, etc.....i'm runnin an axle-back and wondered how much louder with the turbo will the car be? is it better to get a resonator in order to control some of the sound, seeing that i don't want to attract the wrong attention? also, has anyone been pulled over or got a fix-it ticket with their turbo set up? haha, thanks all!

 

turbo'd actually act as a muffling device. the tone should go lower

 

I have a ZPI stage 0.5 with a full ZPI exhaust, which before turbo was loud as crap...in a good way...turbo actually dampened mine down some...Full throttle is loud as ***** at the moment, but mostly because of the open wastegate...ive passed cops and such with no problems...i should add that the zpi exhaust i have is straight pipes with a magnaflow muffler on the rear section and thats it..so i doubt you have anything to worry about...Hope that helps and happy boosting!

 

i just figured with the change in the stock intake manifold, like most cars, ithe sound usually increases dramatically....well at least thats what i had on my old 97 prelude....but then again, i had a racing cat back exhaust which was like 100 db, lol

 

aight cool, thanks....if anyone is down in the oc (ca) and wants to get in on a turbo build in january, lemme know

 

i have an HKS axle back with a megan racing mid pipe.


Piping goes as:

DP, 2.5"...S-pipe, 2.5"....Midpipe, 2.25".....axle back, 2.25"



Dump is closed loop, recirculated to exhaust and when that wastegate opens, it sound MEAN!! Very loud (inside cabine, dunno how it sounds outside).

 

you wanna talk about mean....i have an open dump wastegate lol.....its 100% WTF loud lol

 

I concur....and love every minute of Open WG earblastings!

 

so any people in CA have any problems with turbo noise level? etc....

 

when i had the stage 0 i was running a zpi midpipe..zpi spipe.. and hks axleback.. before i had the turbo it was raspy kinda... due to the lack of air.. now with the turbo i have added backpressure.. causing the sound to increase in a throaty sounding way.. the rasp is gone.. it sounds louder at idle with the turbo but your exhaust sounds more manly lol and less like a beecan and our 2.4l helps out too ..

 

Know what I love about turbo exhaust....mine when its at idle...theres like a mini back fireish rumbling lol in the exhaust....pure sex on the ears...I find myself sitting at stoplights with the windows down when its 40 outside listening lol

 

yeah, i'm just waiting to slap on this zpi stage 0, and listen to the sweet sounds of boost, with an abnormally large grin as the blow off valve chirps in the background....what a feelin it must be, and less than 2 weeks to wait!

 

Let me tell you my friend...first time I went for a drive after the install.....got just a little into boost, let off, heard that beautiful HKS SSQV open up..man, i didn't just smile, i laughed, clapped, even talked to myself saying..."dude...thats effin sweet"....now my favorite is going under bridges/between buildings that you get a nice echo....man i LOVE it!

 

i thinking of taking my exhaust off from the spipe back it will be loud but will deff help the turbo and give u some good power gaiins deff with a turbo, plus u get to hear the turbo all the time.

 

Translation "Hey cop, pull me over please"

 

I live in the Irvine area and drive all over orange county area. I don't have any problems with cops as long as you are smart about it when driving around town you should be fine. Just don't attract unwanted attention when boosted. (Which is hard to do)

 

rhythm, are you runnigna completely open wastegate, or do you route through a dump tube to underneith the car?

 

If its like the ZPI kit i have, its completely open....but i could be completely wrong on that lol

 

errr... dirty engine bay

 

Yeah I know, I thought about creating a dump tube, but i figured if im gonna do that might as well get it welded to the downpipe
