Cool, now lets get some sound installed pictures and sound clips.

PKumarM3 · 02-09-2011, 01:42 AM

i dont understand how that exhaust won't have drone like HPF claims.

Yeah, I want to see this also.

Penn999 · 02-09-2011, 05:17 PM

Im uploading the rest of the pics and videos now, its really loud. Louder than I had expected but its growing on me. I LOVE a loud exhaust, im just worried about the cops, it sounds sick. I need to start looking up exhaust laws in VA. Im gonna go ahead a get my license and registration handy. Im sure its a matter of time...(im gonna just try and clutch as the cops go by, god forbid if I ever get one to ride behind me...)

if its lound use headphones joking, so how u will drive if it so loud? maybe its really too loud....post videos waiting.........u will feel pain in your head and ear soon i think.......

Jake@MOTIV · 02-09-2011, 05:21 PM

Lol - its a nice looking piece but 2k for straight pipes - the company isn't making the sound - the car is. Mufflers are how you change what it sounds like - all the exhausts on the market have the same starting point. The N54 engine has a sound that it will make - then people add mufflers and resonators to get the sound they want out of it. This exhaust is just really overpriced pipes that move the sound from the motor and out to the back. I like HPF but a local shop could have fabbed stainless straight pipes in 3.5" for you for less.

Hmmmm thats what i was afraid of, i would def. get harrassed in NJ.

**335i** · 02-09-2011, 05:23 PM

price is really overpriced

Penn999 · 02-09-2011, 05:30 PM

Its freezing up when I go to upload the videos...I took like 5. Im working on it..throttle response is noticeably better and you can hear the turbos spooling considerably louder.

Forcefed3 · 02-09-2011, 05:34 PM

So really... Is there drone? I wonder how much this would cost at a local shop? The only problem is a local shop probably couldn't do as good of a job.

Why not - its not a turbo manifold. its a basic exhaust with no difficult bends or issues. Literally just a few welds. I would say 600 for stainless locally. Ehh maybe 700-800 because its 3.5"

The two to one conversion probably wouldn't be very easy to make.

Check my sig. for my youtube page. I couldnt upload it on here. They are more coming...

There is some drone..

Jake@MOTIV · 02-09-2011, 05:51 PM

Lol - it has all the rasp. That is retarded loud. Its always fun the first few days. Just goes to show you that a name can sell a product - this product is sub par imho. 2000$ for a few mandrel bends and welds. They can say r&d but thats 100% bs. You are straight up paying for straight pipes. Their profit margin is HUGEEEEEEEe

Thank you for being honest. I unlike many people don't think it's a terrible exhaust, I really like the sound and I think it looks awesome. However, i do agree with many people in the fact that it is going to get very annoying. I would not want to damage my ears like that.

I didnt pay that, thats all I can say. They did do lots of R&D tho, I was working with um through the whole process, thats why it took so long...

Penn999 · 02-09-2011, 05:59 PM
