XK8 exhaust without center muffler
#142
I am confused. There are two muffs/cats right off motor, then the middle one then the two at the back end? Which ones do what? Why 5 of these on the damn car??
Cutting off JUST the middle big muff won't throw codes as these cars seem to be tempermental if you f with them from orig config!?!?!?!?

I had the center muffler removed and an X pipe put in its place. I was disappointed with the difference. I could barely notice a change. Now I'm thinking about having either the mufflers in front of the axle or in back of the axle replaced. I think two of the mufflers are really just glass packs, but I'm not sure which two. I'd like to remove those and leave the mufflers in place. If that's not noisy enough for me then I'll have the glass packs reinstalled and the mufflers removed.

The owner of this site needs update to Vbulletin 3.8.x so they can load the LIVE TOPIC feature which would allow anyone in a topic (thread ) that is hot (many posts at a time) like were were doing, the posts would appear in real time instead of us having to click refresh of our browsers to see new posts. I use it on my yesfans.com site and it is a nice feature.

I'm running the two rear mufflers and the resonators. I wonder if the type and placement of the crossover is playing any significant role here.

Ohio XK has got it. When I removed the centre muffler on my R, I tried going with no crossover. Baaaad. Sounds like some cylinders are missing from the driver's seat. I put a short H crossover and cured it. Still idled nice with a tiny bit more rumble but when you stood on it, it howled. Now with the XK8, I'm going to take XKRacer's advice and dump the two mufflers in front of the axel but leave the centre and the two resonaters at the back.

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.
