BA XR8 Exhaust
Hi guys,
Was a member a long time ago but unfortunately had to sell my old car. But I am now back in a ford on the form of a BA XR8. I'm looking for advice with the exhaust. When I bought it there had been a twin 2.5" cat back manta exhaust, twin pipes went into a big single center muffler then into a large resonator on each side at the rear. with duel rear exit and quad tips. Looked great. But was very quiet. Almost sounded like a 6 unless I opened it up. I replace the middle muffler with twin pipe so it was straight through into the mufflers at the rear. Sounds way better. But still isn't what I want. And it may just be mind over matter but it feels slower than it was before. After doing some research I found that twin hot dogs in the center and twin dogs at the rear sounds amazing, but before I do this is this a good move performance wise? What is the best option performance wise. Sorry if this has been covered before but I just don't know enough about this subject. TIA Kane |
Re: BA XR8 Exhaust
is there a merge pipe or was the merge in the centre muffler? merge pipes kill noise but help scavenging and power

Re: BA XR8 Exhaust
The exhaust fitter said he removed something that he called a mixer. From what I know from the cats there is straight pipe all the way to the twin exit rear mufflers

Re: BA XR8 Exhaust
The mixer as he called it was before the center muffler

Re: BA XR8 Exhaust
that would be the crossover, like and x-pipe but int he muffler. it would sound fluffy without it and maybe more like a new mustang??
got any sound files? my GT sounds too smooth so i'd like to remove the centre muffler i have a similar system on my LS1 and sounds crap just drones |
Re: BA XR8 Exhaust
It sounds a little bit fluffy. I will take some photos and a sound clip later today and post them up. I will have it on a hoist later today. Removing the center muffler definately killed 90% of the drone. And I'm not unhappy with how it sounds now. Just worried that I may be suffering performance wise. No point having a beastly sounding car that is under performing

What does fluffy sound like?

Re: BA XR8 Exhaust
I have extractors, 200 cell cats, x-pipe, dual two & one quarter inch pipes and just two mufflers. I am really happy with the sound, quiet enough around town but when you floor it, its loud and has definitely improved performance. This is on a 302 Windsor, not the 5.4 motor, but the lesson I learnt was to go a little smaller in diameter to aid scavenging and leave off the resonators that most add after the two mufflers. Definitely add an X-pipe as well, it helps smooth out the sound and maximise power. Have a chat to Best Exhaust & ask for Chris. He has been doing this for 30 years.
