De-catting

[gutu12]

Thinking of going ahead with this but knowing F all about the ins and outs of it (a part from it makes the car louder), I thought I may pose a couple of questions to th experts (th ats you lot).

The original cats are more expensive / worth more than the replacement bit of pipes right. So I would presumably get these back from the modifier and be able to sell them on and perhaps?

MOTing will not be a problem but would I / should I be keeping the cats with a view to the future? (whatever that may hold).

Has anyone had a de-cat and paid for the job by giving the modifier their original cats as payment?

Realise this is totally from left field but I've done too much dosh buying the car already and can't justify any more expenditure to the wife. So desperate for more noise though.

You'll need the cats to put back in place to pass the emissions at mot time.

Why not see if you can find some damaged cats and knock the contents out.
This is what I did and then fit them. You can keep the cats you have for MOT time. It's a cheaper solution.

Decatting shouldn't cost much, it's just a matter of dropping the exhaust, removing the cats and fitting the decats then refitting the exhaust. An hours work at your local garage/exhaust centre.

Hi unsure what TVR you have but this is what i did with my Cerb.

I had the cats removed and silenced de-cat boxs custom made (the car was ott loud with the sports exhaust as well) it takes me about half an hour to put the cats back in if need be.

Go for it.I doubt you'll regret it.Sounds soooo much better.Keep the old cats though,just in case.I've got ACT ones in mine.It also reduces cabin heat by quite a lot.

Thanks all. Ordered from Str8six today.
The engine noise / note is one of two things I've found just a bit disappointing with the Tuscan, the low down grunt being the other.

[DAVEY DEE]

Save up for the ACT cherry bomb exhaust,gives a deeper exhaust note.Each to their own obviously,but I think its a better sound than the more "raspy" sound of a Tuscan with cans on.I much prefer the sound of mine since I put one on my Cerb.More of a v8 like rumble to it.

[gutu12]

What sort of cost are we talking Davey?

Cheers

I didn't like the sound of the Tuscan with the cats removed, sounded tinny and like it was pinking all the time. The cats have now just been refitted but the rear silencers sleeved - for me sounds excellent and much raspier.

Even more tinny??? Maybe need to rethink.
I guess the question should be: how do I make it sound like a V8?..... Burble, burble

[clive f]

trying to get a s6 to sound like a v8 is never going to happen, the one thing I really missed when getting my first s6, a t350 was the exhaust note of either an ajp8 or rv8, the s6 is much more revvy, hence a crackling exhaust note, I found a decat with standad silencer fine, but straight through was far to much.

a bigger bore pipe will make it a little bassier, taking the edge off of the tinny raspiness, but like most exhaust noises its all down to personal taste,one mans heaven can be another mans hell

but definately get it decatted, then go from there.

The Cerb has a different rear section but I would imagine around £800.
