Exhaust Modification
Hi all, I have been reading the threads on exhaust and x pipes. I would like to get a little more sound out of my exhaust. Has anyone just removed the last muffler and replaced it with a pipe and tip? How does it sound? Is there someone out there that makes these pipes? Thanks

I brought this idea to my local tech this week, and he responded with support - telling me that removing the center muffler was good for performance as well as sound. He described it as "quite restrictive".
What he couldn't tell me was what effect it might have on the computers that monitor all the exhaust system on an "r" - I'm not looking for more fault codes, warning lights/messages, etc - just some growl for the kitty! Any experences? DaleD

If you look at the pictures of the setup that came with my XK8 the center muffler was removed, I didn't have an X or an H pipe, just straight from the CAT to the resonator then to the muffler. No codes at all and a bit more sound when you press on that go peddle. Quiet when you're on the freeway doing 70 to 80 mph. Just a nice growl when the go peddle is stepped on.

Recommendations?
I've booked a spot at the local custom muffler shop in a couple of weeks and plan on having the centre muffler removed and replaced with an X-pipe. They quoted $150 - $170 for parts and labor - seems reasonable.
After having done some considerable reading, what is the consensus - X-pipe or H-pipe? Benefits / demerits?
Also toying with the idea of also removing the muffler BEFORE the axle. I watched all the posted videos and thought that the sound could be pushed up a little, but wondered how loud it would be with only the muffler after the axle?
I'd love it to be "Sporty", but not looking for "Boy Racer" db levels......
Any thoughts / recommendations?

Sound vs. BHP
I found this excellent article (albeit about a Mustang) that describes the operation of the X versus the H. Interesting point of note is that the X yields more BHP than the H (which they verified by dyno), but consensus would seem to favor the note of the H. Ultimately, you could spend a fortune looking for the right mix of X and muffler that gave the sound you wanted. You pays yer money......
