Hey all, what, if any, potential problems are there in fiting a decat downpipe to a scoob with decat centre, scoobysport back box, baily d/v and scoobyecu?

Looking to take advantage of the groupbuy but need some assurances first, tech hints not MOT advice please.

Thanx.

Skoosh.

 

Shearing a stud would be the worst outcome

The MOT can be passed by borrowing a twin cat centre section from someone. Quite a few people on here have them available. You dont want to swap the DP for MOT as its a 2hr job minimum.

Best outcome is the power after

Forget that. The MOT can be passed on the standard mid pipe if everything is warmed up............easy. But he's right on the shearing of stud thing.............thats a bit of a nightmare!

 

I changed my downpipe in an hour and half last weekend,but i was lucky that every single nut came off dead easy once they were loose.I've got a scoobyecu.de-cat centre section and scoobysport backbox fitted to my car and have had no probs since fitting the downpipe,apart from a sore face with all the grinning

 

std centre will not pass a wrx it has no cat, so that only works for uk cars

 

And you will probably have to trim the turbo heatshield to fit the new DP, Which takes a bit of time.

Need ramps also.

Cheers all, no mention of re-mapping then? Is that because I already have a scoobyecu and it's a my96 pre-facelift?

Doesn't need a remap. But it will work well with the Scooby ECU.

Skoosh, I've a full de-cat on mine - TSL jobbie - As you know, I'm running the original ECU (Not much choice really!)

No probs - or you'd have heard

Pavlo - are you sure the WRX has no cat - my WRX MY94 did in the centre pipe!

Gonna refit it for the MOT later in the year. Are there any markings on the exhaust / resonator / catalyst part of the OEM centre that tell me one way or other?
