whats the advantage?

Just bought H&S down pipe (removes first cat), centre (which i gather removes 2nd cat) and back box.

Are my assumptions correct?

Hi


I have recently done this to MY97 turbo

You get more power, region of 30 hp if you remove all the cats. Faster spool up from turbo, ie boost comes in earlier. Slightly improved fuel consumption. better flat four burble.

Wrap the down pipe in exhaust wrap to keep the heat down in the engine compartment- do this before you fit it. Keep the turbo cover fitted after it has been cut to fit.

mines an 03, just wondering if i will have to make mods to turbo cover to fit?

was going to take to my local numpty exhaust installers, so will wrap the down pipe first!

...i think the MY03 has three cats, unlike the Classics which have two.
Is there not one in the up pipe?

SpoonZ

i thought that but would their really be a cat on an upipe? would be very tight for space as well as anyting else

Yes there is a cat in the uppipe on newage cars, i had it removed along with the downpipe cat and left the last cat in, had it checked at a MOT station and it justed passed the emissions test

SpoonZ

so you bought an uppipe, downpipe and back box? leaving the centre section standard?

do you have a knocklink?
