I have a reasonable exhaust fitted on my '72 XKE V12 OTS. It was developed from parts from Welsh and others, mostly made by Bell. They are:
Interpipe (BSJR141, BSJR140)
Exhaust center balance pipe: C34044
Front pipes (BSJR138 & 139)
Center silencer box: BSJR142
And of course the other misc. parts such as clamps, brackets, etc.
What are the best alternatives for a louder, sharper sound?
I have found:
AJ6 Engineering: TT Extractor Super Sports (& the optional “extra silencer” if its just too loud…)
Note: I emailed them and the owner responded that he is not taking any new orders for a while due to covid & personal reasons. Maybe later but this is iffy at best.
Quicksilver JR022 “Sport System”
Bell JR020, however i thknk this is pretty much the same as the installed exhaust
Are there any other makers of sports exhaust?
Any guidance to what sounds best or any other makers would be welcome!
here is my old car which just had the center two mufflers replaced with straight through mufflers, the same size as the originals, with fiberglass packing.
It is a mild steel system with no rear resonators fitted, and no balance pipe. It has been upsized from the original pipe size.
Just be aware that if you open up the breathing you will have to retune the car, depending on how far you go new needles may be required.
Everyone I know loves the sound, and it is not intrusive when cruising.
Oh, and dare I say it, quite cheap to do. The local muffler shop made the 2 center mufflers, and a bit of larger pipe, job done.
Just leaving the rear resonator off of your current system I believe will achieve the sound you’re looking for. We have not that long ago finished the restoration of an S3 OTS and did that to achieve the sound the client was after. You then only have to get longer pipes to run from the Front Silencers to the Fan Tail.
Your car being a 72 model, originally had the four outlet Fan Tail. The car we omitted the resonator from also had the four outlet Fan Tail and the attachment to the two pipes was achieved with a branch in each pipe to result in four pipes at the Fan Tail. Of course, if the exhaust you have has the dual outlet Fan Tail, then the job is easier.
Your car doesn’t have the correct four outlet Fan Tail, which is effectively a single assemble. Accordingly, you can have the two single pipes from the forward silencers terminate where the four pipes from your current resonator do now, or purchase a dual outlet Fan Tail that is easily attached to the two pipes and at least have it look like an S3 should.
After I got Tweety back on the road, after years and years of dealing with his straight-through, no muffler exhaust, I had to quiet it down a little bit too. The SuperTrapps trips did it just perfectly!
