GT - change of exhaust

Which exhaust would you recommend to replace the raher muted original on the GT 2.0 JTS. Autodelta and Angel have both told me about theirs but I've also been considering the Raggazzon one (is this who Autodelta use anyhow?)

Re: GT - change of exhaust

If I was buying one now, I'm sure I'd go for Raggazzon.

Ideally I'd really want one of the Jap exhausts, but they cost as much as another car so are out of the question!

Re: GT - change of exhaust

Get rid of the pre-cats before you change the back box.

Should release a few horses.

Re: GT - change of exhaust

£300 for a back box is serious dollar.

Get it re-mapped, guaranteed smiles.

Re: GT - change of exhaust

Had all three (inc air intake) done on my 147 2.0 TS and it was the business. I know £300 is alot but if I'm going to stick with the GT I may aswell go the whole hog again

What's needed to remove the pre-cats?
Original intake is crazy.

This is one thing I'm seriously considering along with a modified intake and FK coilovers.

I'm waiting untill the car is 100% before I do anything, still have issues with the car (waiting for parts) and still want to see where my complain to ARUK regarding quality of the car and the underpowered issue ends up.

But, were in a recession and I'm trying to put a hold on this sort of thing in case work drys up completely.

Gulp! It's all adding up

Yes wise option there. I'm lucky enough to know my work is safe but if I were in your shoes I'd hold off

I reckon Alfa should definitely have to explain the lack of horsepowers. It's false advertising saying it 165bhp!!!

Exactly.

In effect, I have been mis-sold the car. I should cut to the chase and get in touch with trading standards.

However, the engines are tested OUTSIDE the vehicles (I'm not sure how) not only by Alfa Romeo but the government too. This means there is no intake and no exhaust present. Which brings the question, how many other cars (petrol) are under the claimed figures?! There was a fellow cloverleaf owner (1.8 TS) which was running 130BHP 10BHP lss than claimed.

Anyway, I think with the intake, precats & back box and a re-map will give you 170BHPish. That will go well, the JTS has got fairly long gears unlike the mountain bike gearbox the diesel has, so it will make good use of the power. I think the petrol is a little lighter than the diesel too.

Yes they have intake and exhaust housing sure the things wouldn't work if they didn't have them. They use what is called an engine dyno which is like the engine is held by something similar to an engine workbench.

They use a dyno then and it is on a power run they have the actual flywheel horsepower of the engine.

And 10bhp less than what the car is qouted to have aint bad really.

There are Toyota Levins with a 1.6 engine which is meant to make about 170bhp and they never ever come even close. Even the Toyota Altezza's which are meant to be 210 don't even come close if they get 180 bhp people are generally happy with them. I know these are meant to be on 100 RON fuel but they shouldn't loose that much power.

It's rare that they make their quoted power figures.

Only 10bhp under is not too bad considering it only had 800 miles on the clock. I reckon that'd be on the button at 140bhp by the time its got 10k on the clock, if it were still on the standard map..

How many miles have you done in yours by the way?

Re: GT - change of exhaust

I think this loosening up is a load of sh1te.

Were not in the 80's working in inches, modern engines are built to fine tolerances these days.

It may rev a bit more freely after a few thousand, but I doubt much power will be gained.

Not once have ARUK tried to say 'it'll loosen up' because they know it wont by anything worth mentioning.

It is actually true mate. The engine is all tight when first built. After a few thousand it's loose as a goose, everything is carboned up and it's running with a lot less mechanical resistance.

Do you think mine will loosen up once it hits 40k

You'll have to push it as you won't be able to drive it fast enough to get it over the edge
