Looking at both cat back exhausts. The Borla S-type (more aggressive) exhaust sounds pretty loud, and the Megan is a tick louder than stock. However I'm planning on a cat less downpipe, 2nd cat, & res delete. Would the less expensive Megan racing exhaust sound about right with the listed above? Does anyone know hp gains with either?

 

Hi FELIX,

Please be advised that these 2 systems are non "Cat-back", but rather, "Axle-back" systems.

The good news is that both systems are made out of T304, rather than T409, which is key.

In terms of HP gains, I would not expect anything more than 5-8 HP. I'm just ballparking, but axle-back systems are 90% for sound and 10% for flow. However, you will definitely start freeing up some flow when you begin with the aforementioned additions.

Please also note that the diameter goes down to 2.25", which is pretty nominal over OEM.

I would take a look at the VIP Custom Parts full-exhaust system. The system is madrel-bent, tig-welded T304 2.5" along its entirety. Since you plan on doing 2nd Cat & Rez, you could avoid having to create some sort of custom setup between the 2nd Cat & Rez delete, midpipe, and axleback. The awesome thing about this kit is that it comes all together, from the DP to the tip, all PNP. Additionally, for the amount you would be spending between the axle-back, a custom midpipe, custom 2nd cat & rez section, etc.... you would probably be breaking even and be able to avoid all the trouble.

The reason I am recommending all of this, is because I wet through that very situation. I started out with the NM Engineering Cat-back. Then I decided I wanted to go with an Akro DP and a 2nd cat & rez delete. I actually had to call VIP and have them custom cut only the front section of their full-exhaust system for me, which I then had to custom mate up to my NM.

It all came out great, and I absolutely love the sound between all three: Akro DP, VIP Front Section, NM Catback.....but if I could do it all over again, I would just buy the VIP Full exhaust from scratch. Please note that there are plenty of other manufacturers and forum-wide sponsors that offer their own full-exhaust systems, which are awesome as well. I am just noting from my own experience.

In the below link is my Page 3 of my build thread, where you can see some pic of the VIP front section and the NM catback. You can see where I mated them, that I actually had to reduce the 2.5" VIP to 2.25" NM.

Thanks guys for the great info! I hooked up with VIP and will go with a full system! Pics to come!

 

Got my CNT cat-less downpipe on as well as my full VIP exhaust. It sounds good, and is a bit loud at times but I like it. lol The mechanic who installed it said there was a small leak where the downpipe and exhaust meet. Still need to add some high temp silicone to it.
