Replacing Short tails for AAM COMPETITION S-LINE AXLEBACK EXHAUST
 

Is anyone running this Axleback? I'm looking at swapping out my Short Tails to something quieter but a little deeper and louder than the OEM Muffler. My current setup is ART PIPES, AAM S-LINE Midpipe, and the OEM Muffler...had to put the muffler back on because pairing the Short Tails with that setup was deafening and headache inducing. Any other recommendations would greatly be appreciated!

Yup,it’s the way the Z should have come from the factory.Little louder and deeper than the stock muffler.No pops or backfires or silly sounds.

Do you by any chance know what the whp gains are?

Excellent choice on exhaust. The AAM short tail exhaust is the best quality muffler delete you can get for your Z with the best fitment I believe but, exhaust among Z enthusiasts exhaust is so subjective it seems that everyone likes something different. I currently have the AAM short tails on my Z because I love a loud exhaust and I enjoy the drone they produce as the AAM short tails are just fine for some but, can be too loud for others. I have had the AAM S-Line axleback exhaust on my last Z and I really liked the way it sounded. The reason why your exhaust combo is so loud is because of the pairing of the ART pipes and AAM S-Line mid pipe together they will increase your volume making your exhaust louder in turn. The AAM S-Line axleback will sound deeper with more tone to it than loud when comparing to the AAM short tail exhaust which will increase volume and loudness. Fitment is spot on with the AAM S-Line axleback exhaust when paired to the AAM S-Line mid pipe. The AAM S-Line axleback exhaust is excellent quality as well made of T-304 stainless steel and is pretty light when comparing to other brand exhausts.

Sorry I'm just now seeing this but thank you so much for the feedback about the Axleback and providing me with more information about my exhaust setup as a whole. I managed to buy the Axleback from someone for 550 with only 1k miles on it and after reading your reply I'm more than happy that I did!
