Injen catback: Too loud

[BronxBomber]

Just pulled the trigger on an Injen catback exhaust. Just had it installed about four hours ago, and the drone is driving me nuts. I purchased this exhaust due to the favorable reviews and also the video clips I saw online. All of the videos and reviews that I've seen stated that the exhaust had a pretty mellow tone and did not drone. Well mine drones something horrible at around 3000 RPMs. This is both on acceleration, and deceleration. It has cobb exhaust hangers. I read A review on Mod bargains and the guy said it was a bit loud up until 700 miles have been put on it and then it mellowed out. Can anybody else chime in on their experience with this exhaust. I'm thinking of selling it and going back to stock.

Make a video of the droning.

Which tip style did you get? Just I case you sell lol

 

[caliboy15]

Ive been always telling everyone.. fswerks ftw!

 

[Plainrt]

I wish more companies made the single tip like injen

 

[DRock]

Bad news. Majority of the time exhausts will mellow out after a but but will also get louder

Remove the sound symposer

 

[BronxBomber]

It's not the sound symposer. I have a Tahoe with flowmasters, 3 Miatas with headers and catback and my last car was a 400hp Subaru with cams, header and turbo back and none of them droned. This is so damn annoying. So my question here is simply if anyone else that has this catback can chime in if they have issues with droning. All I have is a Cobb drop in, Mishimoto inlet pipe, Cobb FMIC, Injen catback and Tune+ time by Adam. Just want to know if this is normal, I'm going back to stock and selling it. I guess I'm getting old, because I'm no longer willing to drive a compromised car. This is my daily, not some project car. My 2 year old routinely rides in it and I know for sure my wife will refuse to deal with the noise. Thanks for all who chime in with their experiences.

i have an injen cat back, raw tip. It drones 3000-4000rpms. If it bothers you maybe go with a Cobb cat back ?

I feel your pain man. My STi years ago sounded great with a Cobb exhaust, but in between it and the Fiesta I had 2 other cars, both of which I put an exhaust on, both of which I promptly removed the exhaust and sold. It was frustrating but the car was just too loud. I too am getting older and that probably has something to do with it. My wife doesn't like all that noise and driving up to school to pick up my kid just isn't gonna work with all that sound. Plus it's just no fun with all the drone and NVH. I need peace and quiet in my life.

Go back to stock!!!!

 

[BronxBomber]

Yeah. The reason I went with Injen is because I planned on going with a DHM quickspool turbo. I'm gonna remove it today and start a for sale thread. Thanks for your input Frankiefiesta. At least I know hats how the exhaust is. I was gonna spend money on putting on an exhaust vibration dampener like BMW uses.

Yeah. Same boat here. I may sacrifice some power by staying stock exhaust but it's worth my sanity. I love a good exhaust note, but I don't do drone. There is no reason these exhausts should drone if designed correctly. For the price of most exhausts(Injen is around $600 on avg) you would think they'd try to make them drone free. I know it's possible as this is the first exhaust I've had that does drone. Anywho. Back to stock and maybe I'll go the Cobb route later on. Haven't even installed my catless DP either, which I won't do till I go bigger turbo. Again thanks for he input guys.

I bought my Injen for the same reason you did, then promptly sold it for the same reason you did. Switched to the MAP exhaust and haven't looked back!

fswerks is amazing. No drone for me. Had it on 6 months.

Cobb also drones. Its not really bad, but It's pretty annoying some of the time.

 

[BronxBomber]

I don't know what to do now. Every other review of the Cobb exhaust that I've read claims it does not drone. I really want to get another exhaust, but don't want to keep spending money buying and installing exhausts till I find one that doesn't drone or have bad resonance. Getting frustrated. Guess I'll have to try and find someone with an exhaust and go for a ride. Won't be easy as where I live, I've only seen 5 FiSTs since last June.

 

[Butterybunz]

Injen drones bad 3k+ which is like 75mph+ in 6th gear. Cruising at 60mph which is how fast my commute to work is there is not very much drone.

 

[StayPuft]

Nothing more disappointing than putting on a mod and not liking it.

Fwiw I have catless dp with stock exhaust and it's really mellow.

 

[no-pistons]

When I had a catless DP + Cobb exhaust drone was almost non existent. However now that I went back to the stock DP, the exhaust became more annoying with drone.

Thanks for your input. I wonder why there seems to be so much difficulty making an exhaust with no drone. Like I said previously. No issues in any of my other vehicles.
