Conradski Posted June 24, 2022 Report Share Posted June 24, 2022 (edited) Evening, My 6 just past its Mot, hooray for a bit of peace of mind, as the man who tests it is a classics expert. Anyway, it has at least one exhaust leak. I'd like to keep the wheelbarrow style twin pipes. Is it possible to upgrade the manifold and down pipe and retain the twin silencers and pipes? What upgrades have folks tried in that configuration? I have had a short look at the usual suspects website but not found anything yet. Cheers Edited June 24, 2022 by Conradski Typo Quote Link to post Share on other sites
Hamish Posted June 24, 2022 Report Share Posted June 24, 2022 Hope you get a real world reply on this perhaps ask the bespoke retailers that do hands on work. TRE, revington, etc they have probably done a version of this and know what fits or get a 4 pot and a sports exhaust Quote Link to post Share on other sites
brian -r Posted June 25, 2022 Report Share Posted June 25, 2022 I am guessing you have a stainless system, in which case most manufacturers make a sports manifold for the 6 and down pipes also. It may be worth checking the OD of existing pipe you intend to connect to. As Hamish said talk to the people that do the work TRE. Revington , TRGB etc they will most likely have the answer . Sorry I can't be more definite but still have the standard system on mine Brian Quote Link to post Share on other sites
Jonny TR6 Posted June 25, 2022 Report Share Posted June 25, 2022 Have you tried Peco in Birkenhead ? They’ve been around since I was razzing around in my Fulvias and should be able to help. They’re local as well, so you can pop round. Quote Link to post Share on other sites
Conradski Posted June 25, 2022 Author Report Share Posted June 25, 2022 Thanks, I did not know Peco were local to me on the Wirral. I'll certainly ask them. TRE and Revington, too Thanks Hamish, hope you go well at Aintree today. I have pulled out last minute. Quote Link to post Share on other sites
BarryC Posted June 25, 2022 Report Share Posted June 25, 2022 Worth also giving Gary at TR Bitz a call -near to you, Warrington. Quote Link to post Share on other sites
whatmore179 Posted June 25, 2022 Report Share Posted June 25, 2022 (edited) Call Phoenix exhausts. They make stainless manifold and systems for the TR6. They make the “wheel barrow” style exhaust as well as original style and original big bore style also a performance manifold. https://www.phoenixexhausts.com/ most of the shops sell these exhausts. Quite expensive but excellent quality. they make adaptors for the systems. I’ve got the manifold and big bore original style system. Had this on the car for over 10 years now.

Nigel Triumph Posted June 25, 2022 Report Share Posted June 25, 2022 I would also suggest Phoenix. Their 6-3-1 manifold fits and seems to give a bit of a boost to mid-range torque, plus a nice exhaust beat. Phoenix were helpful in supplying the bits needed to link up all the pipes on my TR6. That was 15 years ago and I'm still pleased with their manifold. Nigel Quote Link to post Share on other sites
harlequin Posted June 25, 2022 Report Share Posted June 25, 2022 Conradski Please be aware that a stainless 6 branch manifold will offer very little performance increase over the standard manifold. It will however increase under bonnet temperature which will cook the standard type starter motor, once cooked you will have to remove the throttle bodies and the nice new 6 branch manifold again because the starter motor will not come out with it in place. Fuel vaporisation will also become more of an issue but not so much with an injection car. On the plus side stainless manifolds are shiny and have some bragging rights . Spend your hard earned on petrol an enjoy the car! George Quote Link to post Share on other sites
Nigel Triumph Posted June 25, 2022 Report Share Posted June 25, 2022 15 years after fitting a Phoenix tubular manifold, the standard starter motor fitted before I bought my TR6 20 years ago still works fine! Nigel Quote Link to post Share on other sites
Andy Moltu Posted June 25, 2022 Report Share Posted June 25, 2022 Having tried the regular exhaust systems on my 6 including the twin silencer system I would not waste time on finding a link for a sports manifold to this system. Pretty sure the likes of Phoenix supply the link pipes. The best IMHO is a 6 to 3 to one manifold and a single exhaust. The volume being determined bt the silencer you opt for.

Jonny TR6 Posted June 26, 2022 Report Share Posted June 26, 2022 My car came with a tubular stainless manifold. I’m thinking of the best way to reduce heat to the throttle bodies and also starter. I don’t want to wrap the manifold as this can cause issues, but thinking of a heat shield of some sort. I’ve read up a bit ne you can get one for the carb cars, but not injected. Is this because the PI throttle bodies don’t soak up the heat as much as carbs ? My throttle linkage is the underslung type as well, so potentially getting expansion of the metal and associated issues with fuel delivery. Am I being unnecessarily cautious ?

Conradski Posted June 26, 2022 Author Report Share Posted June 26, 2022 These replies are all very helpful, thanks everyone. I will talk to some of the usual suppliers as recommended, especially the guys at TR Bitz. I may leave it until the Autumn as I cured an exhaust leak today and the 6 is running miles better, ..... and less fumigation in the cockpit too. Quote Link to post Share on other sites

Jonny Fuel vaporisation is not such an issue with injection as there is no reservoir of fuel in the throttle bodies and the fuel is under much higher pressure then with carbs. My car has carburettors and I tried all sorts to prevent vaporisation to no avail, in the end I sold the Phoenix manifold and reinstalled the cast iron standard manifold which cured the problem.

George That’s great info - many thanks George. Might knock up a heat shield for the starter though. Quote Link to post Share on other sites

George I've got carbs with the Phoenix manifold and don't have these problems? But I do have 2 air ducts blowing over the carbs from in front of the rad. Quote Link to post Share on other sites
harlequin Posted June 27, 2022 Report Share Posted June 27, 2022 My TR6 is my daily car, it is also used for touring so is subject to the occasional heavy traffic and Southern European weather. What finally made me make the change was getting stuck in a jam in the Eastend of London quing for the Blackwall Tunnel during a heatwave. My broken down car caused absolute chaos, I learnt lots of new words that day George Quote Link to post Share on other sites
