I am planning on getting mufflers swapped on my '05 V8, and am wondering if it is worth it to swap the stock cross over with an x-pipe. Any gains, better sound, etc.?
X-pipe swap
- Thread starter JoshMcMadMac
- Start date
They have a chamber in the middle where both pipes go into. Some call it another cat, but some say it's not a cat. Most are doing x-pipe. I've heard benefits over x-pipe over no x-pipe and since thats what i currently have since I took out that center "cat" piece. I'm going x-pipe this weekend

How do you get around emissions inspection in Kalifornia, I know here in Nevada they physically inspect?
I have only done it once, when I bought the car, everything was stock though. Why the question though? I still have my cats which is the biggest deal isn't? That third chamber isn't a cat, it was empty. The guy at the shop said he removed it cause it was empty and I always wondered how all the material in the "cat" fell off, but turns out it's not a cat, it's empty. I dont think I'll fail because of that
That piece isn't on the '06. The exhaust is just like the 1st gen; an "H" pipe after the resonators.

Which part, the crossover? Why are you mentioning the '06?

I have an 05 V8 and I dont have a third cat either, I have an H-pipe afer the resonators.

maybe replace the h-pipe with the x-pipe?

That's the best thing and what most people do. X pipes equalize the pressure between the exhaust pipes better for increased velocity and scavenging.

you can do that on a gen 1 too right?
It's too far back in the system. You would need to install it after the point where the pipes separate from the cats, ahead of the resonators.
I have 2000 with v-8 and h-pipe is towards rear of car right before resonators stock. I now have custom exhaust and have installed an h-pipe closer up the exhaust where they first come down under body. I noticed a big difference in power and sound!! BTW i have 2.25 inch piping all way through except for mufflers which are 2.5 center in center out and they are cherry bomb extreme mufflers and tailpipes are 2.5 inch too!
