after reading some older posts about tvr building problems
jacked my car up today and dismounted the exhaust system from headers to backside.
the chassis above the CC's is really in a bad shape.
paint is blisterd and material is full of rust
going to fix this once and for all

Maybe after you've sorted it it's time to decat to reduce the heat. I used some heat shielding and decatted, sounds great with more pops and bangs.

Res, im concidering doing this. My only thought is that i dont want the car too loud as i use it alot really. It has standard cans etc does yours? I would be interested in hearing your opinions on the noise change following knocking the cats out.

don't fancy a very load car either.
will have a look how this turnes out
thing is that i don't often drive with the top off
i think that makes a big difference
have owned an heavily upgraded esprit se turbo before without cc's and an open exhaust.
the noise in the car was ok but my wife could hear me coming from about 1 mile distance. it helps that we don't have neighbours.
they all moved away :0))

will post my experience

Do, let us know how loud it becomes inside the car - that would be my concern.

As would passing the MOT with no CATs, which is why I'd be loathe to destroy them.

I'd prefer to replace them with pipes, if I could get hem, as I did with the Cerbera. Then the cats can be refitted for MOT day.

What do you do to repair the damaged chassis. I am hoping to get decats soon, mainly due to the damage the cats cause to the chassis and the possible destruction of the engine. I presume I will some heat damage to the chassis too.

Cheers

yust to let you see what damage the cats make to your chassis
i'm going to sand it and paint it again with heatresistant paint
over that i'll put a piece of heatresisting material

i don't really need to pass the MOT
i've got a guy that will do the test without the cats
he also helped me out with my esprit.

made a pic. the rest of the chassis is 1a
the wet spots on the manifold is WD40

I decatted mine recently, have now covered 600 miles, with all sorts of driving and i really like it.

I hate loud exhausts and am very fussy with it, but the decat pipes ive fitted (TVRPOWER) fitted a treat, and they are not really that loud.

Yes it pops and bangs on the overrun, but not offensively. I expected alot more noise.

At wide open throttle they are awesome, again not offensivly loud, but a nice fierce roar whic i think makes the egine sound powerful.

At cruising speeds on the motorway its fine, i can hear the radio and its civilised enough to not make you go mad.

my chassis is also rusty like that, i bought some of that DeoxGel that ive read about on here, seems to be a very strong rust treatment, and the manufacturers claim it restores the metal to perfect. Ive tried hammerite products on the past andhavent been too impressed.

fixed !
the car is decatted now and i don't really find that it's a big difference soundwise on the inside.
THE CAR DOES FEEL LIKE HAVING MORE TORQUE
if you drive normally there is no difference in the sound level (more pops and bangs)
if you open up it sounds like an animal
awesome
i like it

Good work!

Did you smash out the old cats or buy new pipes?

The new pipes sit further away from the chassis then the cats so all helps.

If anyone has a spare bit of heatrestraining material they aren't using i could do with about 10 inches x 10 inches.
for a small sum £.
