Another Headers / X-pipe / Roush Axle Back thread.

[Abe71Z]

Ok,
So my combination is as follows:
2015 Car
JBA Long Tube Headers (1-7/8" Tubes, 3" Collectors)
JBA X-Pipe (3")
3" to 2.5" Transitions at differential
Roush Axle Backs (2.5" Mufflers).
All V-Band Connections.

As stated by others with similar combinations, it's beyond loud.
I understand the cold start can be toned down with a tune, it idles fine once warmed-up, and rips when you get on it.

My issue is with the mid throttle and normal speed up rasp & resonance, it's full retard.
I would like to see if someone else has, kept the headers, x-pipe, and straight through mufflers, and found a solution.
I was thinking of adding some 3" resonators right after the X-Pipe, in the same fashion as the GT350's.

Let me know what you know!
Thanks

Are you catless? If you have no cats then that's part of your issue with this set-up. I'm going with catted LT's in the next couple months and if its unbearable, I will likely go with the Xforce Varex axl-back so that I can tone it down a little if I want it. I know its more money, but at least it allows you to go full retarded loud when you want it and tone it down when you don't. Someone just posted a new vid on Youtube with a catted headers, x-pipe, X-force axl back with a Roush blower that really shows the difference. This is the route I'm likely to go when I get my Vortech set-up with LT's done in the next couple of months.

Different setup but just as raspy / loud. Corsa Xtreme direct connect to ARH catted LTH. Put a pair of Vibrant 1794s on and cleaned it up and toned it down quite a bit. Right after mufflers before the double x similar to below.
