After bouncing around trying to decide on a non-resonated, catted, or resonated midpipe, many hours of searching the forum and youtube, I finally decided on the AAM Resonated Midpipe.

I also bought a 90mm to 70mm reducer to avoid any exhaust leaks.

 

With my bad back I decided to take it to a local shop for install.

 

1st problem, their 4 arm lift would not reach the front jack points without damaging the side skirts.

After over an hour of trying they finally used two scissor jacks to raise the car up enough to get the arms under, and again when lowering it to get the arms out.

Note to self: Buy Reverselogic Jackpads (at least 2, most likely 4).

After that the install was easy.

 

Now for my impressions....

 

At 1st start-up I was a little disappointed, car did not sound all that much louder, but I was in this as much for the rwhp gain as I was the sound.

I decided to take a local ride and see how it sounded, i let the car do the shifting (I did not use paddles), again I was disappointed in the sound.

 

Next day it was pouring rain, but I needed to see about drone so I needed to get on a road where I could check out drone.

I took a nice 1-2 hour ride. I was only able to do 65 on this road, so I used 5th gear to achieve 2500-3000 rpms.

No drone at all.

Still I was a bit disappointed in the volume.

I started to use the paddle shifts and this made it sound better, but still a bit quiet.

 

KEEP READING

 

After another day or two of driving to and from work and using the paddle shifts, I guess the resonators break in some how,  the car sounds so much better and significantly louder.

 

My dogs hear me coming home from a nice distance away according to my wife.

 

I have not had a chance to test the power increase, I commute to work in a pretty congested area, but the sound is really nice.

 

It sounds very much like a sport exhaust equipped Porsche to my ears.

 

At 2500-3000 rpms you can hear the car humming nicely, but not droning.

 

I am very happy with this purchase.

 

I do need to buy jack pads.

 

Many thanks to Chris Riggs from Speed by Design (while on vacation in Italy), they were out of stock on the reducer, he hooked me up with a previous customer who had a reducer and gaskets.

thanks, I was in a rush and did not get to write all I wanted, but when using the paddles the car sounds so much better.

I had Greddy Non resonates midpipe. Sounds deeper. Slight drone. Switched to full AAM exhaust with resonated midpipe. A lot deeper sound. Than just midpipe and no drone. There might be better exhaust out there but I got it used for a good deal Sent from my iPhone using Tapatalk

Very nice detailed write-up and glad to see you have it installed. The resonated MPs sounds nice and refined on the outside of the car without the headache from drone on the inside at 2500-3000rpm. How does the car feel HP-wise?

Drone is a killer, I did not want to risk it, glad I went resonated midpipe.

Maybe a catback, but while under warranty I will try to hold off on anything that requires a tune.

I am not sure as I have not had a chance to go full throttle since install.

Ordered 4 ReverseLogic Jack Pads today, $150 is not cheap, but I want the peace of mind that I can change tires, oil, brakes, etc...

at any shop without worrying.

correct, but it is resonated as opposed to non-catted and non-resonated

no tune required, I did not want to void my warranty.

It is an easy 15-20hp and it sounds better, well worth the $$$.

Picking up a Kline Innovation catback today from a buddy of mine, it was too quiet for him, let's see how it is with the AAMmidpipe

Downpipes is where the fun really starts.

Downpipes is where the fun really starts.

No ready to do that yet, since the car is new to me, I want at least a year of warranty to make sure there are no issues before I really start to play.

 

I know this goes against what most say, but since adding the catback to the car, it feels faster than with just the aftermarket midpipe.

 

It now chirps/screaches the tires, it never did that before and it is warmer out, so it is not cold weather.

 

As far as sound, it does not sound much different than with midpipe alone, so for a sound basis it is not worth the $$$.
