Invidia has just released two new exhausts for the 2012 Civic Si Sedan and Coupe. Both look amazing IMO.

The Invidia Q300 Exhaust is designed for customers who want a "mild" street exhaust, with a deep sporty tone that isn't too loud. Amazingly though, the Q300 still produces great power gains.

The Invidia N1 Exhaust is more aggressive, in both looks and sound. It is geared more towards all-out power, and the gains are more noticeable at higher RPMs. Plus, it comes with a nice looking burnt titanium tip.

For more information about each exhaust, follow the links below:

The images are actually from a 2DR Si application (I believe), but the 4DR and the 2DR look virtually identical.

I've seen your videos on youtube! You've got a nice ride!






That's his car w/ the Q300 on it.


I've heard that the 2-1/2" systems are better than the 3" because 2-1/2" exhaust gives more gains in the midrange where as 3" systems typically give their gains in the higher range.. This opinion is shared by a lot of the people in my local car club.

So which one is a better system, the N1 reminds me of the old greddy ti-c catback exhaust I used to have her I miss her, is the n1 like her? So the n1, is a little louder, really? Or for more performance? I have a takeda Cat back exhaust love it, but kind of want something with a little more roar, so people hear a nice clean, deep tone, and say dam I like that, which I get, but I love that tip haha lol

I just installed my Q300 on friday. So far I love it, it sounds a little louder than stock and in my opinon is the best exhaust! Only problem is for some reason mine is banging on something, I have to double check if I left anything loose, but besides that this exhaust is great!

That's basically the exact sound I want. Not too loud but can still hear it. I want to be heard to a degree but not all the time. From what I've watched from the 8ths the N1 could be heard even from a slow take off and was quite loud. I know a guy with a q300 on his type s and he loves it.

Plus I think a downpipe will make it a little louder to find a good medium

Invidia n1 rattling noise

Hello,
I installed my invidia n1 exhaust system on Friday and this morning I noticed that when my car is idling or at low rpm that my exhaust makes a rattling noise. It almost sounds like it's hitting something. Could it possibly be that the stock hangers are too short and the muffler is hitting my bumper? Or could it be the heat shield?
Thanks,

Invidia Q300/N1 Civic Si

I haven't seen any threads that are officially about either of the Invidia exhausts yet, other than a couple by procivic and import dps stating that they were available to purchase. So I'm gonna start this one as an official thread for anyone who wants to share info or pics or anything else concerning them.

I purchased the Q300 from wesellcarparts.com for a great deal: $509 with shipping included. It was a pretty easy install, my cousin in law and myself got it done in about 45 minutes. Very simple.

Overall I am impressed with it, it is noticeably louder, at any given point in the rpm range. I picked It because I didn't want something too loud...I'm not gonna be THAT guy who wakes my entire neighborhood when I leave for work in the morning. It also is bearable at highway speeds as well. It definitely growls when you get on it, anyone around can hear me, I'm sure of that. It also looks great too, excellent build quality, and fitment is great. I have had it on for about 4 days now and i havent had any rattles or leaks at all. As far as power gains, I haven't dynoed yet, as I'm waiting for a dp, but its noticeably quicker from 4000 rpms and higher.

Highly recommended for those guys who want a good exhaust that is livable yet also has power gains and gets attention when you want it to.

Pics below! Don't mind the bird poo on my bumper, I must have gotten bombed on while I was at work since I parked under a tree :(
