Exhaust Too Loud

Recommended Posts

I have a Vitesse Mk2 convertible which is great in all respects apart from the exhaust system. It sounds lovely around town but on a long run at about 2500-3000 rpm the noise is unbearable so much so that I have to wear ear plugs otherwise after about 1 hours I get a ringing in my ear and can't hear properly. This kind of takes the pleasure out of the trip :-(

 

Anyway... the current set up is a 'wheel barrow' stainless system with two boxes at the back. I do not know who it was made by. I was thinking of going to a custom exhaust place to see if they could make up a very narrow centre box (anti-drone) but it probably wont be cheap so I was wondering what other people could suggest?

 

On the TSSC shop I see that they sell a 'standard' stainless system but does anyone have one to say what it like? Also is would be a shame to loose the twin exhausts.

 

Any advice gratefully received!

Cheers

Jim

Jim,

We sell three systems for 2 litre Vitesse models, Standard, Semi Sports and Full Sports. You have a full sports currently fitted, don't know if it is one of ours or that of another manufacturer, however they all follow the same pattern. This is by far the loadest set up and also you lose considerable ground clearance as well. The standard system follows the original Triumph Mild Steel set up for shape, layout and design, it will sound a little different to a mild steel exhaust because of the different resonant frequency of the stainless steel. Finally the semi sports which is the same layout as the standard system, but the back box is free flowing and has a larger tail pipe. The sound is richer and louder than standard if you drive the car "on cam" otherwise it is not much louder than standard. In my opinion it is the best system to go for and it is what I used to run on my GT6 and currently run on my Herald.

I had the canley classic "std" exhaust on mine. A tad louder than a normal std system, but bigger bore silencer. 

That was great, nowhere near as loud as the wheelbarrow systems. (just ditched the one that was on my spitfire, too noisy on the motorway, and also a bit small for my new engine!)

Old Spitfire of mine failed the MOT many years ago when fitted with a TT twin silencer system for being too loud - it was loud, but I hadn't bought it to be a shrinking violet ;)

 

Went back to Mr Hurrell who smiled and said, 'hmmm, we did have some that were like that!' Straight swap for a pair of back boxes with acoustic tail-pipes which had a very good note to them - I don't think they are available from anyone these days.

 

I'd tend to agree with Garth that the 'semi' sport is probably the best bet if you are not a fan of too much noise.

You should be able to get a cherry bomb type of silencer that will fit, but be warned clearance is tight between the chassis rails. But I doubt it will make a great deal of difference.

Alternatively, you could try a "db killer" type device. Or rather a pair.

Another thing to consider is the noise created by resonating panels.

 

Driving my GT6 used to be like sitting in an oil drum. Much like your description.

 

I've fitted sound deadening self adhesive tiles everywhere I can. The engine and exhaust still sound great but life is a lot more civilised now. (My car also has a semi sports exhaust).

no idea what these guys are like they do a wide range of affordable tails   eg.

i took the wheel barrows off the Vit6 due to sounds like a hair drier and gravel  grabbing and reverted to a club herald /1600 semi sports single which 

sounded absolute music,  this was with  631 and 2" pipes , the silencer sleeved inside the long pipe   Magic  on song !!

I've got a similar (first world) problem with my Spitfire exhaust and plan* to find a local exhaust specialist who makes custom exhausts and see what they recommend. I'm hoping they can pop the silencers open and add some sound absorbing material to them. These sorts of places tend to do most of their work in stainless so should be set up to re-weld the boxes.

 

 

 

 

* I have to confess I've been saying this for about 10 years without actually doing it...

Ok then it looks like I may replace the twin with a single system. I was looking at some other threads and someone mentioned that the semi sport system was nearly as loud as the twins? Is this true as I do not want to spend my money and be disappointed. Will there be much of a change in drivability if I went for the standard system?

Beware of people saying "it's not much louder", cuz different people perceive noise in different ways. One persons "sporty note" is another's "$%^£ me - that's loud!" I also had the wheelbarrow system and, like you, had to resort to ear plugs. (I always go to live music events with ear plugs, or my ears will ring afterwards.) My best advice would be to get along to your local group and see what others have. Cadge a ride to see what a system *really* sounds like.

 

Cheers, Richard

 

PS: After someone spends a load of money on something, they often convince themselves that it's good - even when it isn't. That goes for exhaust noise too!

Just another thought (and there are probably good reasons not to which people more educated than me will point out) but someone once told me they had put a motorcycle exhaust baffle inside each of the twin pipes to reduce the loudness. Believe they are available on certain auction sites in different diameters. As i say, just a thought...

A friend has recently fitted a dB killer to his spitfire system to get it through scrutineering on the local 12-cars, dropped it 5dB so halved the volume.

 

Do you have a photo of your tailpipes, the system can usually be identified from that. Phoenix systems are about 2" and have ends turned in, TT systems are similar but smaller diameter. The Phoenix boxes are longer than some of the other ones.

 

The Bell systems have shorter boxes and straight tailpipes that reduce in diameter as they enter the box.

I've almost moved house to one about 400 yards from a housing estate and one young lad there has a 'sporty' Ford Fiesta. His mostly home made mods include a very loud exhaust. Almost every day that I've been there I can hear him starting up, revving the engine, and driving off through the village - and for miles away afterwards, roaring off into the countryside. I hear him leave, and come back, and so does almost all the village - to the extent that I've had my new garage commented on as "more bl**dy noisy cars."

He obviously thinks it's cool....

A couple of months ago i removed my old 1986 Triumph-Tune twin box system as i was fed with it keep hitting the ground.I had a single box system custom made from the manifold back with the box sitting up next to the rear boot rigger.

 

Sounds great if you give it a boot full but quiet on a motorway.

 

Manifold is a Mike The Pipe 6-3-1.

Sorry for the late question but I'm interested in the need to have a mid box or not. I think I have a semi sport rear box on the GT6 but also have a mid box and kinda presumed that this was necessary irrespective of what tail pipes you went for

 

The image shows the twin pipes sports but no mid box

 

Is this an option for the semi sport that I have to help it breeth better ?

 

Thanks Kevin

Mid box helps reduce noise levels. I just added one (re-engined spitfire, 175bhp and big exhaust to match) and teh mid box made a significant difference. In a very good way. As in I don't feel deaf after a drive. They are straight through boxes, so will have blittle if any effect on performance.

I have a stainless standard system but it's 30 years old and on it's last legs. The stainless steel is not leaking but two of the welds have split and I think the baffles in the rear box aren't right! I have been listening intently, on club nights, to other systems and have decided. Full sport? No! Painfully loud and poor ground clearance. Semi sport? Sounds lovely, but for a longer journey? Regretfully no. The standard system. It just looks right, dangling under the back end, unlike the other two!  It sounds like a straight six, without frightening the neighbours. Less is more.  So it's going to be standard system from the club shop, unfortunately, the most pricey option  :o
