You can reach out to topspeed directly too. I think they were the seller on ebay.

I am actually running the topspeed pro axle back 1 with mufflers. It gives it a nice deeper tone without being nuch louder. I'm also running the autokitsx v2 kit. The tips are a bit big and may touch the diffuser a little. Topspeed has their own website where you can purchase their exhaust. Also there are websites such as conceptzperformance, (where I got mine), that also sell this type of axle back. If you do not want topspeed specifically, there are other exhaust brands such as manzo or tanabe that could work for you. Depends on your price range and what you want.

I have a 2012 convertible and have recently installed the Top Speed Pro 1 plus Kinetix Hi flow cats , I bought it off of Ebay BTW I paid $485

I had the axleback with no mufflers with my autokitsx v2 diffuser and like one poster said, the tips were really close the diffuser. It didn't get burned but it wasn't the best fitment. Maybe you'll have better luck adjusting the it though.

Additionally, while the exhaust tips look good against the OEM bumper, the tips look comically small when paired with the AKV2 diffuser.

I'm now running the ARK CBE with the 5" tips with the AKV2 and it looks way, way better.

But I absolutely loved the way the car sounded with the axleback. My favourite exhaust set up I've had so far when it comes to sound. But looking for a Motordyne exhaust now lol

Coming for an ARK and now running the E370, you're gonna fall in love once you get the MD.

This seems to be the consensus but being from Canada, the exhaust will run me 3K easily...difficult to justify but God the youtube clips make it sound so perfect...

I'm running ART pipes too so I'd probably complain about the MD being too loud haha (which is still better than being too quiet, I guess)

If you want loud and don't care about performance then just do a muffler delete. Pay for some nice piping/tips so it doesn't look ghetto. Who cares what ppl think as long as your car still sounds good IMO

A couple years ago I paid $470 for my topspeed axleback (I'm in Canada) which is literally a muffler delete with decent piping. Could have probably done the exact same thing for $300 at an exhaust shop.

I'm running ARK + ART pipes now, but my favourite setup I've had on the car for sound is the muffler delete + HFC lol

Okay thank you, will most likely just do a muffler delete then because the stock 330hp is more than enough haha. Do you think it's better then to just have an exhaust shop cut the muffler out and put their own pipes in? I was looking at some axlebacks as well, but like you said just having a shop do it seems much cheaper.

It's a crapshoot depending on the shop. Custom work vs factory made.

axis.

My opinion is either snag an axleback (I'm assuming you're in USA so it's cheap) or go to a custom shop and ask for quotes to fab up a piece and then determine what's more worth it to you. I don't like the idea of hacking up the OEM exhaust in case you ever need it again but the end result will all be the same lol
