Decat Question

[BLOODUK]

Awhile back i went in for a powerflow exhaust loved it ever since, but i couldnt afford the extra £40 for a decat and they said it maybe difficult to do cant remember why hmmm...

Is a decat worth it?

will the car be louder or just 2bhp faster?

Or just i just skip it and save up for a downpipe

A similar question was posted recently.

Decats seem to be better on turbo's coz on N/A's they can cost you low end torque. It should give around 5-7bhp and make the car rev more freely. Should also make the exhaust sound deeper and make it pop more.

[BLOODUK]

Nice thanks Dawolf , i love it when it pops

[BLOODUK]

Aussie De-Cat Pipe where do i get one anybody know and how much?

[Jesus]

Fensport... about £238 + VAT.

Well worth doing. I can't emphasize how much so.

My cat is getting decat in the garage now.

blueflame charged me £275 for a decat pipe + stainless exaust + fitting :)

mine is n/a

[ZeroBlade]

i've got the mongoose one for my N/A (came with the mongoose zorst). I havta say it does sound decent, but as dawolf said they tend to decrease low end toque, which i noticed on my car!

Looking back it's prolly not the best thing to do if you want performance for an N/A, as that low end will prolly be more useful!

Just had my car back...

Major disappointment...!!!!!!

Lost all my torque at the bottom end, feels like driving a 150bhp car now...

I only get 0.5bar at first 2 gears...then 1 bar at higher gear..I will get a new sparkplug and hope it will get better...

if you got a N/A.... don't bother..

[ricomr2]

That shouldn't happen with a tubby... the power should be up mate

Maybe try re-setting the ecu?

[tony4]

thanks rico... i will try that tomorrow.... :( :(

[BLOODUK]

Did they put the Sensors back if they took them out at all? meh i think ill get a downpipe now instead of just a decat i hope u get your problem sorted tony... and as rico said TRY resetting ecu

[tony4]

He replaced the lower pipe, so there's no sensor on the bottom part. He told me that the upper sensor will do the same job

[tony4]

HELP!!!!!

I'm only getting 0.4bar (1-5th gear) after resetting the ecu..

ok, I only have the Engine stem clean, tighten the HKS bov one turn and decat.

PLEASE HELP!!!

[BLOODUK]

Im still taking a wild stab at this and saying he shouldve left both sensors in!

[tony4]

Are you pretty sure on this??

In that case I will be in deep s**t..

Can anyone without the lower temp sensor tell me about me... no offence to bloodUK...

[BLOODUK]

I know for a fact its best to keep the sensor's they are there for a reason not just for show

[BLOODUK]

MY dad just said

YES.... its the sensor , that probe is there for a reason what ever that guy did just buggered your car IT NEEDS TO GO BACK IN!

[tony4]

thanks for your help BLOODUK.

I might just need to readjust the MBC...hmm...

But I really need someone running without the temp and confirm is the same case before I embarasse myself in the garage.

[tony4]

sorry for hijacking your post Blooduk

that's what I get from other forum

[BLOODUK]

What does it say? sorry buddy not regged

[BLOODUK]

My dad said the sensor removal probably retards the fuel

[Bibbs]

I got a de-cat .. infact, just got the stock one gutted and the sensors are still in the stock locations with no issues ..

I had a MBC at the time and it needed no adjustment ..

[kalmr2]

just checked with mechanic mate who confirmed exactly what BLOODUK said about retarding fuel and such...........you'll probably see a lot of celica gt4 cat's on eBay saying 'ready to be gutted',

my mechanic says this can be the best way but, just drilling a hole and firing the sensor back in should fix it!

(he's no specialist toyota bloke or 'ought but he's fixed all the probs with my car and f**k me there's been plenty)
