I've done the same mod to my XKR that I did to my KX8. I took out the center muffler and added a H crossover. It's mellow at normal acceleration or cruising speed but it's much louder than the XK8 at hard acceleration. I'm not sure I like it and am regretting not keeping the center muffler to reinstall so I can try removing the others. Oh well. It doesn't sound bad, it's just really loud when you're mashing the pedal to the floor.

My XKR, now with straights replacing the center muffler, seems to have a little flat spot in the 2000 rpm range (gotta look closer) since I eliminated that huge center muffler. Maybe a crossover or x-pipe would eliminate it. It's not a big deal, but I'd like someone else who has access to a dyno to evaluate these options.

I haven't seen a universal H-pipe, but they probably exist. I know they are really big in the Mustang world, so there are a lot of them available for them. That said, they are simple enough to make (my exhaust guy did mine in about 10 minutes while I waited, he did the rest of the system and then couldn't remember what I wanted so he waited for me to pick up the car to finish)

I eliminated the center muffler months ago, and the XKR seems to run great, but I have no way to directly compare the X-piupe setup, even with the change, as I think the effect would be small. Anyway, a local muffler shop did the job quickly and cheaply ($40), and would have done the H or X mod easily, and I didn't have to crawl under the car and try to weld.

I haven't seen this till now, but thanks for the offer. I ended up putting a new Borla 2x2 in followed with a Mina exhaust with the NP cats. I don't think many vehicles have ever sounded this nice.

I have removed the center muffler and installed an x pipe...sound did increase and the tone was good. I thought I might like a bit more noise and then had the pre axle mufflers removed as well. Noise increased considerably. These little mufflers are flow through design and do quite a lot to tone the exhaust down. I might have been ok with them off but there was some drone under load but worse was a "trumpeting" brassy sound at wot at mid to high revs. I had them reinstalled. I may consider replacing the rear mufflers with borla now but it is sounding better with just the x pipe.

Stevec,
A few months back I put up a post about modification(s) to my exhaust. I don't mean to hijack this thread, but in case you want to see and hear the end result, I have some videos on it.

Hi Devspider...Thanks. Viewed your video and your exhaust is a bit too aggressive for me (just a personal preference as you have said in your first post)...However.. I do like yours better with the x pipe you installed as I think it gives a more mellow tone. The XK coupes can get away with a more aggressive exhaust note as it seems to suit that body style. I have a convertible and I just feel the really loud set ups don't match up with the rag tops as well as they do the coupes. Once the snow melts here I will get my xkr out for a drive and evaluate the exhaust with a fresh perspective after missing it for the last 4 months!.

I'm back on the road now - being very mindful of potholes that can swallow the whole car.

I removed the central muffler and found the noise thrilling under acceleration but a definite power loss on the low end. The shove in the gut is gone but revving beyond 4500 sure became more interesting.
That said, I can't live with that setup. Either the center muffler goes back on to get my power back or perhaps an H pipe is in order.
Love that WOT sound though.

I removed the center muffler and put straight pipes in its place, just to see what it would do. Sure enough it sounded like a low rider with "twice pipes" and glass packs. I then added the X pipe in the middle and that did 2 things, quiet it down somewhat and second it made the exhaust sound like a proper euro sports car. It is still pretty quiet and at idle no rumble. No drone at speed either. Just a tasteful bit of throatiness when under acceleration. I can't feel any power change at all, nor did I expect to. I believe the stock center muffler has an X pipe inside it.

Has anyone tried removing the center muffler, replacing with an H crossover straight pipe, leaving the two mufflers in front of the axle and removing the rear most mufflers?
The result being the two middle mufflers only with a straight pipe.
I saw some videos from DaveC where he added an H with two glass packs in the center position and took everything else out, just straight pipes all the way, sounds interesting but I'd like a little more refined sound.
One more thing the XK8 and the XKR seam to sound differently with modifications, would everyone please note which car you are working on, thanks
