Here's a video I just took this morning. Unfortunately, same conditions - cold and not under load. Yes, it will sound raspy. I will try and take a video when its warmed up so that people can really hear the difference.

BTW .. do NOT have your speaker up too loud after you hear the startup (love the growl!). The wife guns its good unexpectedly and its like a banshee.


When it comes to a loss of power from the x-pipe, I could not say either way. I haven't noticed a loss of power but I do not tow or even drive it daily. I have no regrets doing the x-pipe.

Lol I love that start up sound. Holy crap.

Yes please try to get a warmed up sound, and maybe under load. Thanks.

So true!

Twins are you still running the crossover or did you switch to the pipe? I know we had a thread about those before. Still haven't put mine on because supposedly the crossover doesn't help sound as well.
Oh here it is.

X-Pipe sounds good...

I strongly prefer the sound of a straight pipe to an x-pipe. Straight sounds more deep and throaty, x sounds more smooth and high pitched. Could almost be mistaken for a straight 6 in my opinion.

Mine sounds very deep...

I love my straight pipes. The mufflers restrict sound so much.

Looking back and checking again, I think they are one and the same. So, I was incorrect in that thread. Sometimes they call it just "Tru-X pipe" other times they call it "Tru-X Crossover pipe". I still have the same thing. I didn't change anything.

Its the universal version of the "Tru-X Crossover pipe" that looks different. All the others are the same.

Man, I can't live with losing any torque. But those sounds are great. No, no, I think H-Pipe vids are in order too.
