Just got my Q300 in today. Can't wait to slap it on tonight.

Hey Guys,

I have a question that i hope someone can help with. I have the invidia N1 on my 2015 fg4. It was rattling so i bought new hangers and that seemed to fixed my issue. However, a couple months later the rattling came back? I attached an image of where the exhaust seems to rattle. My car is lowered on coilovers? could that have anything to do with the issue?

Thanks.

Thanks.

Most likely the exhaust is rubbing the rear spring. My full race system did that on my tein coilovers. The rear spring is wider diameter than stock.

I have a 2012 Civic Si Sedan, would an N1 exhaust meant for a coupe fit on it?

 

Not direct fit, Sedan Exhaust I believe are 2" longer than coupe versions.

 

After 3 years with the Q300 my feelings are pretty mixed.

The Positive:
Ideal exhaust for a daily driver. It stays pretty quiet in town when you want to be discrete, and when you're driving hard it provides a nice subtle baritone to compliment the screaming vtec induction sound.

The piping itself is very high quality. After 3 years of salty NY winters the exhaust hasn't even developed surface rust (except on the gaskets.)

The Negative:
The design of the Invidia exhausts causes significant droning at 3k RPM especially off throttle, this can be irritating on long highway drives.

As many others have discussed, the axleback will rattle against the heat shield when the exhaust gets hot.

The midpipe hangs extremely low. If you're even moderately lowered (~2 in) this will scrape pretty often. I'd imagine the stance people probably can't even use this exhaust.

Gasket's have a very short life span. I didn't expect to have a gasket fail within a few years of ownership. Not a huge deal, but not really acceptable at this price point.

Overall I'm happy with the Q300. Its a much nicer sound than stock that won't get you in trouble with your neighbors or the police. That said, I get the impression that Invidia rushed to make the Q300 compatible with our cars and left some pretty annoying oversights. The result is a very high quality exhaust with a few low quality problems.

 

I'd agree with Mr. Tentacles. I've got like two inches of drop and my mid pip is destroyed. The 3k vibration also syncs up with something lose in my b pillar that annoys me to no end.

 

Installed my Invidia N1 exhaust the other day... Man does it sound good, pretty loud when RPM's are dropping but other than that it's great. Drone isn't too bad either. Is it true that after a week or so of driving it quiets down a bit?

 

No it won't get much quieter the N1 is loud and stays loud.

 

Ordering a q300 for my 2015 si coupe soon. I am wondering what is the difference between extended version and the normal one, as there is an option for this in Procivic. Thanks

 

Why don't you email and ask ProCivic that would be the logical place to start?

 

Can you show pictures of how your q300 end muffler sticks out from the 14-15 coupe rear bumper? In my q300 the end muffler sticks out very short and I wonder if that's ok.
