Exhausts again
Discussion
Had a look at my exhaust on the 350 whilst wheels were being changed and lo and behold after nearly 3 years starting to fall apart around the silencer - Genuine TVR as well.
So what i was thinking of is a side exit type to amuse the neighbours. Anyone know rougly how much and where from ?

There is no commercial kit but NACNUD has done this on
his SEAC .. drop him an email.
He did it - one on both sides .. and for ground clearance reasons.
. Normal system though so maybe doesn't help.?
There are 2 cars both SEACs which have the side exit pipes, Nacnuds & Karl cordwells, Karls exits from one side with a large oval pipe, Nacnuds has the "T" piece with a tail at either side. i would exit from one side, 90 degree bend after the centre box blended into 2 pipes to improve ground clearance.
Cheaper than standard system as there is less pipework, you would need to make a mount under the sill.

Hi all!
Yes, I originally fitted it for ground clearance because the roads around here are not only rough but have excessive camber. Remember that SEACs can't have the exhaust routed over the half shaft and the 'standard' SEAC routing is under the lowest point of the car, the differential cradle. I sometimes still catch the diff cradle on the road and any exhaust routed there would quickly be trashed.
There are a couple of pictures clearly showing the exhaust on page 40 of this months Sprint (Feb).
The standard SEAC silencer is retained and it splits at the back of the box to exit on both sides of the car. Mounting the exhaust might prove tricky on some Wedges because the chassis mounting plate doubles as a jacking point. This is not a problem on mine as there is a whopping great plate welded to the chassis which the roll bar is mounted on.
At the back of the box it's more of a Y piece rather than a T piece, but the current bend radius is possibly resticting gas flow at high revs. I'm looking to have it redesigned with sweeping S shaped curves.
I have to say that I've grown to really like the sound from the side pipes. Sound bounces off anything I pass making an intruiging V8 soundtrack that a rear exit exhaust can't compete with. Burbling through built up areas and stone walled lanes is now a real treat! Overtaking is fun as well because as I pass the car the acoustics change dramatically!
The only down side is that those lovely resonances under bridges, etc, happen much less frequently. I think it is because the sound is coming from two sources pointing in different directions; each source having only half of the volume of the original tail pipe.
Before I had the side pipes fitted I got a lot of comments about legality, etc. But since it's been fitted and people have seen it in the flesh no one has voiced any concerns.

Duncan,
Daft question of the week. Why can't the SEAC have an over the shaft system? Maybe cos the boot floor is lower if over the NS shaft?
Mine has the same space at the rear around the shaft as my 400 (even with the twin alloy fuel tanks) though it does go over the OS shaft and straight out rather then over the NS and across the rear as per 400SE.
Thoughts.
Nice photo's in sprint BTW

Not a daft question at all and too be honest it's a long long time since I compared the insides of different wedge boots. I think it goes something like this.....
My boot interior is symmetrical. The top of the diff cradle is completely flat between the wheel arches.
I believe that in non SEACS there is an extension to the NS wheel arch bulge to accommodate the exhaust hence the interior is non-symmetrical.
I can't remember which model Wedge I was looking at. Being a TVR the odds are that they vary from model to mdel and possibly even car to car!
When I had all my ground clearance problems I did discuss the over the half shaft route with Peninsula and they showed me why it wasn't possible. But I'm very fuzzy about the details now.
I'll be intruiged if it's shown that I'm talking bollocks; but one thing is for sure - I'm not losing my side pipes, I like them too much

Oddly, I have never found evidence of heat buildup on the bodywork around the new exhaust exit. I thought it might get hot, but it doesn't!
It might be because there is really good airflow at the outrigger.
Also, the exhaust gasses are blown clear of the bodywork and unlike the rear exit are unlikely to get sucked back into the car. I don't get any exhaust deposits to clean off after a good hoon
