I just installed the FRPP GTA mufflers (Shelby GT - H) on my '07 GT/CS. They sound great and the tips are the best. when i ordered them, i also got the X-pipe. I have not put the X-pipe on yet. I have seen a few threads that say the X-pipe will take away from the deep sound (and i don't want that). Should i just forget about the X and keep the H on?

 

As the first person on this forum to install both the FRPP/Shelby X-Pipe and the GTA's, I can tell you that the X will only make it sound better. It will not take away from the lower sound of the GTA's. I get compliments on the sound all the time.

 

I liked the way my x pipe made my car sound. Go a head and put it on

 

Here is a video of GRAYPNY's mustang with Shelby GT Axlebacks & FRPP X-Pipe YouTube - GRAYPNY Video

 

I've read that FRPP X pipe will generate a higher pitch tone , but Craig has personally attested that it doesn't, and by the sound of Graypny's vid, I'd say go for it

 

That Graypony car is awesome.When my garage floor thaws out the FRPP X-pipe is going on.The temps are up the snow is melting.I'm ready for Spring

 

Hey Grabber, you have defiantly had a white Christmas! In General the X- pipe under hard acceleration does produce a different sound note! I wouldn't say its higher pitched put that X-pipe on if you don't like it theres always other options..

 

GRAYPNY doesn't look like that anymore but thanks for the compliments. The GTA and X-pipe combo just keeps getting better and better as I put more miles on it. People ask me all the time what kind of exhaust setup I have. A big thanks to Graig for being the test mule!

 

I like my GTA's Even without X-pipe. I get lots looks ad heads are turning on parking lots when I star my car up.

 

Guys:

I was just talking to a guy at a place called Galpin Auto Sports here in LA - they do alot of work on Mustangs. I asked him about the FR Axle Backs and FR X-pipe and he recommended Bassani X pipe, high flow cats and Magnaflow axle backs. He showed me the Bassani which had a much larger opening between the pipes.

I had rented a Shelby and loved the sound of WOT, so I was looking to duplicate it when I get my new GT - hopefully soon.

Anyone have any thoughts on the combo he recommended vs. what you guys have?
