To decat or not to decat, that is my question

[wongthecorrupter]

Thinking of decatting my 4 litre Tuscan,what are the advantages and disadvantages and where have you all brought your decats from.
Cheers

Advantages - Louder, Bigger more explosive backfires, More power if chipped for it, Gearbox doesnt burn your leg.

Disadvantages - Car stinks, Some say its too raspy, Its a bugger taking them off and back on for the MOT

Needless to say i run decat!

Was your car mapped for decat

Can you buy the decat eprom as a part or do tvr power just supply and fit

Has anyone used under bonnet heatshielding to prevent the heat damage?

I have and my bonnet is still crazed

Mine was mapped decatted, so if I put the cats back in it might kill them very quickly and reduce power. But I do find it too raspy without!

You find it raspy with the cats out

It hasnt worked on my car

I've got some very small end cans on mine which stop the raspy noise without reducing the volume or bangs.

Are the small cans standard

I've just fitted some standard cans and the rasp is much much less and the general note deeper/quieter!

Thats what i needed to hear,my car has std cans

Decats fitted yesterday, the car runs a lot cooler now and it takes longer time for it to get to temp where the fans kick in.The noise i like and it is not that raspy, the backfires are mental though,they are more like small explosions.I havent had chance to open it up yet (to much traffic) so im just hoping it hasnt changed the power delivery in a negative way.

[so roll me further bitch]

Would a de cat and straight through cans affect the performance of a speed six in any way, i remember the lack of back pressure on my chimaera when it was straight through made it a little slower.

Decat chip is your friend

I can still remember the first drive after decatting. It was like the shackles and chains were finally off.
I think my Tuscan was smiling that day too.

I have the de cat chip, i seriously think my car was quicker with the cats in

[so roll me further bitch]

Does anybody think speed sixes are to loud when decatted and straight through cans.

I bought my tuscan already decatted (longer header pipes) but with the standard rear cans, it was not a great sound until well on the throttle tbh, sounded muffled and puffy. So I sleeved the rear cans and OMG it sounds beautiful. nice and burbly at low revs but crazy when nailing the throttle. best mod so far and cost me 1 tenner and 1 hour in my lunch break

Does it get to loud on longer motorway runs

How do the ACT decats compare to the Clive F ones
