Changing my sport exhaust back to 'standard' ?

[Kerry]

While i really love the sound of my current exhaust, I do find it wearing on longer journeys (eap motorways) so have decided to replace it with a more standard one.

 

As it is the manifold appears to be standard that has two pipes that join the rear twin silencer section shown, so wondered if anyone has any recommendations or do i just simply go to one of the usual suppliers and order a rear section (guess also in stainless).

 

Also would i need any addition fixings to revert to standard too ?

 

Cheers

It really depends on how "standard" your existing system is. There's a risk that if you just buy the rear cross box from one of the suppliers it might not be compatible with your existing front end. I would guess that for the difference in costs it might be as well to get the whole system with all the hangers and know it will fit. Go for the standard cross box rear and enjoy the sound of a 6 as it should be without being raucous. You'll probably get better rear ground clearance too.

[Alec Pringle]

Agreed, twin box systems often enough incorporate the OE pattern downpipe from the OE cast manifold, but all the pipes from the downpipe backwards tend to be specific to the particular 'sports' system.

 

Therefore you'll need not just the rear box/tailpipes but also the full length of intermediate pipes between the downpipes and box.

 

And a full fitting kit !

Thanks Gents, had a feeling a full manifold back system would be the way to go

Get the Phoenix cross box exhaust. It's a big bore with the cross box which looks original.

It will fit the original manifold with a kit

It's a lot quieter than the one you have but still sounds fantastic when you give it some ( a little louder than an original though)

You can buy direct from Phoenix or moss.

I had the twin 'wheel barrow' sports system on my first TR6 in 1983 - sounded great, but tiring on motorway driving; called the wheel barrow system because you could pick up your TR6 and wheel to the side of the road when it broke down, but of course they don't break down anymore...............

 

If I was buying now, I would go for the Phoenix cross box system as Steve has on his 6.

Sounds louder then the one i have =

[Andrew Smith]

That's the sports 6-3-1 system, a completely different system and not the cross box, see: http://www.moss-europe.co.uk/exhaust-system-twin-pipe-standard-cross-box-stainless-steel-pxs5202.html

I have the system which Steve describes and I agree that it is quite a bit rortier than the standard system, but much less wearing on a run than the sports exhaust which I took off, in my opinion.

 

When I asked the tester what he thought of the exhaust note when I took it in for its last MOT, he said "it sounds like a TR6 should!"

 

Before you spend any money, maybe some of your local group have a selection of different systems which you could listen to?

Looks like i am in luck, another forum has offered my this at a very good price, has a few dings as you can see but I guess they will not be visible !

 

[Andy Moltu]

The Phoenix cross box sports one is quite loud - considerably louder than my straight through single pipe system.

 

An alternative option is to get the silencers replaced on your exhaust system (by an exhaust specialist like Custom Chrome in Nuneaton) with suitable alternatives that will make it more civilised. This may not be as expensive as replacing your entire system only to find it just as noisy or noisier.

[Kerry]

Thanks Andy, problem is Nuneaton is a long way from me here but I know of a specialist not far from me, might be worth giving them a call - cheers

Hi All

 

Long time lurker here. Me and my Dad have owned a '71 TR6 since 1989. It needed significant recommissioning back then, including the exhaust. A previous owner had fitted an early type of performance manifold (6 into 2). The rest of the system was shot so Dad got a twin Double S in the 'wheelbarrow' pattern. My grandad, who was very old school, hated it from day one and always said it was like a "bee in a bottle". You could hear the car coming from streets away. Frankly it was unbearably fumey with hood up or hardtop on and the back bumper was always smutted-up.

 

Fast forward to a couple of years ago and, after another extended period off the road, we got it up and running again. It all came flooding back how unpleasant and uncivilised the exhaust was so with a deep breath the whole lot was replaced. I went through all sorts of soul-searching and considered all the choices. The manifold had gone pretty thin (mild steel) so was junked and it is now on a standard cast iron manifold and a standard pattern exhaust system in stainless. Within seconds of starting it up and during the very first journey my Dad and I looked at one another and said we couldn't believe we'd lived with the horrible rasping, howling Carlos Fandango thing for all those years. It is the biggest, most transforming change we've ever brought to the car. Refined but with a thoroughbred sporting burr to it. No fumes and a clean back bumper. Personally I like the OE look too. I've almost never seen a 'wheelbarrow' that it absolutely 100% symmetrical.

 

That's a very long, rambling way of saying I can only recommend a standard set-up!

 

Cheers,

 

Steve

Not at all rambling Steve, in fact a very nice story to go with the sound (ha!) advice, cheers :-)

Back in 1983 I fitted an SAH twin system and it was bloody awful, lasted a month and was fitted with a standard system. Wonderful. Never had the desire to change away from standard since. I do run a mild steel box though with the rest S/S. I find the standard mild steel box better sounding.

[elclem1]

Yes go mild steel standard, stainless can be very tinny.

[Colin White]

+1 for original manifold, standard system with stainless pipes and mild steel box.

[Tom Fremont]

I've had the standard system on a TR250 with a stock engine, then stainless on same, kept it that way at first with triple Webers and Kent cam, then wheelbarrow system with factory dual hole manifold, then 6-2-1 stainless manifold with single bore pipe and muffler, then changed to Phoenix TUV approved " quiet " muffler where it is today. Short video attached for sound sample.

 

My show car has the 6-2-1 stainless manifold with the single bore pipe and large bore cross-box muffler ( triple Webered engine with steroidal cam ). It's quite a bit louder than the one in the video and I wouldn't like it for long distance use. Regrettably, Phoenix no longer make the " quiet " version single bore muffler, as the small perforated stainless tubes they inserted into the bore are not available now.

 

In sum:

 

Stainless is louder than mild steel, and tubular manifolds are louder than cast iron.

 

If I were shopping for a system now I'd go with the highest performing one I could find ( factory is fine for factory spec engine ) and go to Phoenix to see about reducing the decibels on a bespoke basis. I still have a glass fibre packed single bore muffler which preceded the current one in the video. It was almost as quiet as the one on the car, and was done by request before the current one was supplied.

Thanks Mike, appreciate the information (and video, must have taken ages to upload)

Hi Kerry

 

A long while ago (3yrs+) I got fed up with grounding out with a twin exhaust system and took the plunge and had a tailor made system fitted from the bottom of the manifold to the rear. The key thing for me at that time, was to retain a s/s sports system with twin pipes that didn't ground out on ferry ramps, etc. So briefly the requirement was to design a single pipe with flange joints wherever poss, made easy to remove and a horizontal box, (oval shape), tucked up under the gap between the boot floor support and the diff, with 2 pipes coming straight out either side, as you have on your current exhaust. The interesting part, was that they could design the box to be sporty or quiet or very sporty. I chose sporty and although it's very nice, I think I would now choose quiet. Anyway, it took a day to fit while you waited and cost about £600. Here's the link.

Best Bill

Well, just back from Spiro of Classic Cars Cardiff, he kindly replaced the exhaust and so much better. The M4 drive back was almost a pleasure with the added bonus of no exhaust smell (at least while your moving).

 

First time i have met Spiro and a nicer a person you could not wish to meet, went oit of his way to sort out a mess up by the exhaust supplier (parts missing they had been ordered etc) - so very happy indeed
