Ebay decat downpipe

[adsgti]

Hi folks,

I've decided to take a punt on a ebay 3" decat downpipe after reading that rtech recommend using them. It seems a slightly better design than some with the small flexi also as this seems to be around 6" on the photos.

My question is can I put it on the car without any adverse effects for a while before I take my car for the stage 2 tuning? I know it will throw up the eml light on the dash but that doesn't bother me as it will be mapped out.

Thanks in advance for the help.

As you said, the EML will come on but thats it.

Have had mine on for a couple of months with no issues at all

Sweet have you noticed much difference since putting it on?

Cheers.

Just curious as I'm thinking of doing this myself.. Does the EML light not cause you to go into limp mode when planting your foot down or am i thinking of something else?

Cheers,
Carl.

Nope, just brightens up your dash

Louder and certainly feels its giving more when booting it.

I already have a 3" non res catback and revo CAI hope it's not too loud though. Could always have a resonator box put in I guess, ill let you know what it's like Carl.

I read that a common problem with the eBay downpipes with the small flexi pipes putting strain on the welds leading them to crack. The one I have bought has a much bigger flexi than most ebay cheap ones, comes with heat wrap and an option of 3" bore or the downsized pipe to mate upto a standard system. Delivered for £135. I'll let you know what quality and fit is like!

Surely just fitting a decat without mapping to suit will result in massive fueling issues and probably produce less power than a standard car

I thought there may be issues myself that's why I have asked, not getting it mapped till about February and was wondering if I should put it on or not too 

[Matthewsimone]

I would personally wait until ready for map mate as wont be any quicker and mpg will be terible too

I'm looking to get a new DP .. I had my car mapped 2 months ago.

Would I need to get it mapped again?

[adsgti]

Yeah it would need to be mapped to get the best from the downpipe would be alot less than the initial price you paid tho as they would only need to tweek it

Make sure you do the mods in here to protect the flexi pipe:

This is why flexi pipes fail, too much engine movement

Yes mate its http://m.ebay.co.uk/itm/161490555267?nav=SEARCH

Seems pretty decent. Should arrive today I think.

What difference in gains will I see between having a decat or just a 200 cell sports cat? Debating buying a 200 cell magna flow sports cat and getting it welded in??
