Invidia Q300

[codylibertysti241]

Anyone else got an Invidia q300 turbo back system? I have questions

[alexxxz]

as do i!

apparently its a very noisy exhaust (noisier than the xforce) can anyone confirm this?

Yeah I have one, complete turbo back too. It is loud. I think it's a combination of a few things. 3" stainless pipe is one thing. I installed an additional 18" resonator to try and bring it down a little, sorta helped. I had my exhaust guy look at the mufflers too, apparently there are bugger all baffles. I'm just going to sell the muffs and install something else a little quieter. They definitely don't restrict the flow that's for damn sure, and they sound good when you give it a flogging. They would sound 10 times better on a manual, not so much with the 5EAT.

I have one of these on order now, speaking with Troy from PSR that the new stock is "quieter" so will be interesting to see what its like.

After my Invidia carboned up, the Db levels dropped a fair bit. When cruising, the car was quite pleasant. Only when WOT was applied was when it got louder, but not uncomfortably loud. I like it.

How long did it take to quieten down?

1-2 weeks of daily driving.

I've had it in now for 3 months, get driven daily too. Not much change at all

Interesting. It's one of the first things I noticed. If it's still too loud, you'll need to consider fitting a resi.

Funny you say that, that's the first thing I did. I fitted an extra 15" resonator right behind the existing 10". Not a lot of difference at all. A waste of $200 really. It's the mufflers ay, they're just plain loud. Not enough baffling

Mine is pretty good, quiet until given the boot.

Is the car tuned at all or running the stock tune?

What mufflers are you running again Cody?

Invidia Q300 twins, twin tips

ah ok. Not sure what they are like. As you said they could have less baffles built in. Maybe look at the TCP Auto twin tip muffler group buy and sell the Q300's?
