Hey people I just had a question.... so basically i bought a Topspeed Pro1 Exhaust from a friend for my 2004 G35 6MT as soon as he installed it for me right from the start it sounded badass..it was loud deep and really growly*..
for the first couple of weeks of having it on it sounded amazing anytime i gave it some throttle in the lower gears and in the tunnels it sounded like a Nissan GTR lol...now i realized it sounds nothing like it used to ...its been about a month or so and its not as loud for one nor is it as deep or growly*...
after i put a new air filter and got my oil change done the noise kinda came back but then within almost a week it was back to the more quiet tone...
If anyone has any ideas on what i can do to get the sound back i would really appreciate it thanks

You prolly just got used to the sound & now you want more, I say get a intake & you will hear a little more growl.

Lol i thought it was that as well but then i heard the video i made of it when i bought it and even my buddies who i see once in a while noticed it....intake is something i was considering but i want that sound back

bring it out to Blain's meet on the 18th and we can give it a hear

Yea i'll be there but just to give you an idea here is the first start up and drive when it was just installed...


im uploading a current video of what it sounds like now on youtube i'll post the link up as soon as its finished uploading

sounds good nitish , i actually liked the sound of the topspeed when i first had it wasint 2 loud to begin with, after HFC's got a lot louder lol, i think you just got used to the sound.

btw,

That silver 350z, u know the owner? he was @ a wedding yest we were dj'n at , nspire sound.

^ yeah i have seen him he was at my cousins wedding too

lol yea he's the one that sold and installed the exhaust for me... did the whole thing for 4 bills i really like the sound...its just not what it used to be....you'll hear it on the 18th trust me its a lot quieter...like a lot lol

Looks like after u drive hard for a bit it warms up and sounds a lot better...but again no where near as loud lol

edit

LOL you think your exhaust sounds too quiet???

I didn't even know this was you at the meet....as I said, I think you had the best sounding exhaust

dont drive your car for a week it will all come back.....i have the injen and hfc's and you start to get used to the loud when you dd it

Adriano add me aman toor-nspire on fb .. Any1 as well

Btw, nitish I thought ur exhaust sounded just perfect !

haha thanks a lot guys

idk if anyone said this, but when you first put it on, the car had not learned the new flow parameters and sounded really well. once the cars computer computes all the changes it adapts and compensates. when i did my HFC and Amuse exhaust i was like oh yeahhh, and then after a few days realized that it got quieter but was like oh well still sounds good. but later i learned what i just told you from a local tuner that know these cars like the back of his hand.
