347 mustang borla XR-1 mufflers

I am changing from XR-1's to the Pro XS mufflers and i wanted to see the difference in sound. That is why im using a sound meter. I will post the video when i put my new mufflers on.

Yes, 3"

I dont remember exactly, but i think they were around 12"

[slostang89]

No I went with a custom cam from Ed Curtis

[slostang89]

I actually already changed it and turbo'd it. I went with an Ed Curtis custom grind

[slostang89]

This cam was .638 in .667 ex lift .254 in .264 duration @ .050 lift on a 106

the car sounds smoother, was this after megasquirt?

@twynne2929

Yes this is after megasquirt, but before getting it tuned. This was just a base tune. if you notice i had to go rev the engine to get it to stay idling.

The car is being torn down right now to be turbo'd i will post a video when im done.

did you stay with same cam after putting turbo on ? by the specs seams like a lot of duration and valve overlap with 106 center line just asking for when i have cam made for mine thanks .car sounds fantastic
