OK so now my cars been sorted and it cost less than i thought I'm considering putting a decated DP on it

Other than the DP what considerations do I need to make

 

Helloooooooo anyone there

Do I need a knock link, lambda link, boost guage ?

If I do why

 

No you don't.

Fit it and enjoy

 

Cheers Pete

 

Had a 3 -2.5" open neck SS down pipe fitted yesterday and all I can say is

WWWWOOOOOOOOWWWWWW!!!!

Why did I wait so long ?

 

You *might* need to do something with the boost control to keep spiking in check when the weather gets colder which *may* induce overboosting.....

Rock solid boost control because its an RB5, not an STi7.

Get back in the cupboard

 

...yeah 'cos nobody ever had any problems with a PPP + Decat downpipe and overboosting did they?

What do you think set John Banks on the path?......

Matt

P.S

 

Nothing cleaning out the wastegate and surrounding pipework didn't fix and even then, only after a dealer got generous with the oil filling at service.

97/98 cars were a bit more sensitive.

 

You did notice theandright Pete?

I've been thinking about fitting a de-cat downpipe to my RB5 WR Prodrive.

What sort of power increase would I expect?
Does it make the car noisier?
What's the best downpipe out there?

Alternatively, would replacing the PPP ECU with a standard MY99 and going for a TEK2/3 be a better option?

confused - please help!
