Invidia Q300 Catback + Berk High Flow Cats installed.. disappointed..

Diversion · 07-10-2009, 09:36 AM

High quality versions will be available soon once Youtube catches up with the process..

Sorry about the sound quality, I think my tripod covers up the microphone some. You'll have to crank up the speakers im sure.

Cold start with a little revving..

Warmed up all the way with some revving..

Really disappointed with the sound of the Invidia.. it's horrible over 4k.. lots of rasp, sounds pretty crappy, like a cheap exhaust is installed.. Maybe the Berk HFCs make it sound like this =(

People might want to stay away from this combination of parts if they value higher quality sound out of their exhaust. It sounds good up to 4k, then this loud metallic rasp takes over. Not only that, the cars feels SLOWER than just having intakes =( And i'm 99% sure there are no leaks.. we had the car up on a lift to check for leaks and did a pretty thorough job of checking.

Thoughts?

Invidia exhaust are known for their fine built quality with rasp sound!!!

My friend has Invidia exhaust for his Acura RSX, and it was raspy. It really doesnt suprise me that you have the similar sound.

Haven't you done a research/youtube and listened before purchasing this exhaust?

Diversion · 07-10-2009, 01:17 PM

Yeah I listened to the videos of other owners with Invidia and theirs didn't sound like this! I almost think I might have an exhaust leak now under WOT and partial throttle because if I slowly rev up, it sounds good.. anything more it starts to sound like butt =(

ArticReaver needs to check in and give me some thoughts!

m4a1mustang · 07-10-2009, 01:22 PM

It's probably the HFCs... they will make the car sound more raw/raspy and if the CBE already does it with stock cats then you get this.

Diversion · 07-10-2009, 01:36 PM

Crap.. It really makes the car sound crappy.. and why it's feeling slow is beyond me too. Guess i'll consider selling now.

ECU might not have adjusted fully yet which could be why you are feeling a power loss or no difference. But yeah, the sound will continue to suck.

kevr6 · 07-10-2009, 05:05 PM

Thanks for the info!
I just bought the exhaust and thought it was better then stock but still mild so Berk HFCs was next on my list. I wonder if headers would help out the situation at all???
I'll still try the combo then just get another exhaust if need be since I got a good deal on this exhaust!
We'll see!

Did Eddie Murphy put a banana in your tailpipe?

Viera · 07-10-2009, 10:16 PM

Ewwwwwwww

davidyan · 07-11-2009, 12:03 AM

Although there is some rasp, I think the majority of the noise is due to something loose. You can hear the ringing which means something is not tight. Did you check all the rubber hangers, gaskets between pipes, etc?

Diversion · 07-11-2009, 08:06 AM

Nothing is loose guys.. it's how the exhaust sounds.. I crawled underneath and re-torqued all bolts and checked all gaskets for any blow-by. Nothing, looks clean..

While driving I know the rasp is definately coming out of the tailpipes only, no weird sounds from anywhere else on the car..

I'm going to give it about 2 weeks and i'll repost a video and see if there's a difference.

Also, I was remembering there were a lot of packing peanuts that got inside the HFCs during shipping, I hope I didn't accidently leave 1 inside one of the HFCs! Could be the horrible smell i'm still getting! Lol.. oh well, it'll burn out.
