Just purchased a my99 a couple of months ago and quite satisfied,am starting to do the odd performance add on.Are the benefits of a de-cat downpipe noticable and worthwhile,(what are the costs).Secondary,what are they like to fit as ive been under the car for a routine check and it seems this area gets its share of salt and water and have visions of sheared nuts everywhere.Thanx

 

The answers to your questions.

(1)They are worth while with a full system (up to 15-20 Bhp)
(2)Price £120-£250
(3)There are a few options, Scoobysport,Bpm,Tsl,Hks,Blitz,Scoobymania,Magnex,S corpion,Jap innovations,Graham Goode,and it just goes on.

Personal choice is a Scoobysport

Regards fitting its not an hard job but if your not sure get it done by someone who noes what they are doing.

Very noticable

On a car that is around 3 yrs old there would be a real chance that the studs/bolts would be siezed...if you are not ok with this go somewhere and get it fitted.

Well worth doing!

 

I've not done the down pipes yet (next thing on my list ).
but i've done the rest of my system and its made a difference.
It took me 1hr 2 undo 2 bolts from the down pipes,next time i'am going to pay to get it done

GET IT DONE M8

Will look into gettin one hopefully next week.do you know if there will be any probs with the mot next yr with front de-cat pipe and rear scoobysport box,although the guy i use is ok and into scoobys so hope it will be ok.Thanx

 

i think in most instances they still gothrough the mot if they have one cat left on, eg centre cat, however my old my99 did go through an emissions test with no cats in!!

 

Are all de-catted downpipes 3" dia???

Do they all have the adapted flange for the waste gate???

 

no they are all different, endless amount of threads you can look at.

some have twin dump downpipes, some have bell mouthed, some start at three and shrink down to standard at the centre, some stay at 3 plus al the way back.

play your cards right and the choice is yours

 

Decat downpipe was the best mod i ever did, until i started changing the ECU's and all that malarkey.

Just be aware it does make the car a lot noisier. Make sure that's what you want. Most people do. I did, up to a point, so i had mine lagged at the time of fitting by Scoobysport, and that took the edge off it quite nicely to me...

I can feel another mod coming on as i have a standard down pipe with a cut here line penciled on it and as i have a enlarged flanged i can use.

Keep an eye open for the thread once i have done it, you may be amazed
