Ebay Sports Cat 100cell.... Pics & Fitted
« on: August 16, 2012, 05:54:46 pm »
Hi all,

This might be of use to some people......

I purchased this from ebay for a stupid price, as it was worth a punt (seller has these as a auction also):

http://www.ebay.co.uk/itm/VOLKSWAGEN-GOLF-MK5-GTI-2-0-FSI-TURBO-STAINLESS-STEEL-3-SPORTS-CAT-EXHAUST-PIPE-/220959138790?pt=UK_CarsParts_Vehicles_CarParts_SM&fits=Model%3AGolf%7CPlat_Gen%3AMK+V&hash=item337230e3e6

These are the actual pictures:













I had this fitted by a VW specialist to my Leon Cupra (same engine as the ED30) today & it fits perfectly.

The garage was impressed with it, for the price!  Now my car has a roar when you put your foot down.  I can't comment on whether it will pass an MOT (mine is next month, so can update if anyone is interested) or how long will it last.

But if you don't want to spend £600+ on a brand name, this is a very good alternative!

Looks good! :happy2: How does your butt dyno feel about it? And did the carage use the clamp that came with the DP, is it decent quality?

The flexible joint looks rather short imo... I believe Milltek run a shorter(but longer than that) flexible joint and have known to crack the flange weld...

I just placed order on the same pipe :party: Hopefully its as good as you say, thanks for the tip :smiley: I have full engine mounts so Im not worried about the flexi joint. The unbelievable prices for these catted downpipes have put me off for buying one before.

Just be aware that the actual cat internal component (which you can't inspect without cutting into it) is a very expensive part of an exhaust system. What quality is the cat on a £240 exhaust system I wonder.

Yeah the garage used the clamp.

I was worried about it being too loud or getting vibrations (thats the reason I didn't go stage 2 while it was being fitted)... I wanted to try it out 1st, as these look pretty new on the market (with the sports cat).  But everything is fine..... not too loud when driving 'normally' & a roar when you floor it!

I'll update this in a few weeks when my MOT is due.  With a buy like this - only time will tell if it's a good one!

Ps what is the flexi joint?

Flexi joint is the part before cat, its supposed to flex  :smiley: Please do update the MOT experiences after you get it done. Did you get a lot more power with this?

Without any ability to flex, some components have a greater risk of breaking. The 2.0T FSI engine with OEM engine mounts has a lot of movement and can also break aftermarket air intake mounts when attached to the side bracket.

You'll notice that exhaust systems are fitted on hangers which are flexible.

I received my catted ebay downpipe and took a couple of photos.

Heres the package, the v-clamp doesnt look too quality but hopefully it will do the trick. I might need to find some high temp sealant for the connection. Welds look pretty good, atleast better then my squat bench  :smiley:


The 100 cell cat here. Looks like it will flow a lot better then stock, not sure if it will clean air :wink:


Its already rusted inside :happy2: But the flex joint _looks_ like its leak free.

I installed the downpipe today. Seemed to fit pretty good, although the support hanger near cat didnt line up perfectly. I had to use some force to get left side hole to line up. The sound didnt change much, I already had a precat delete and this downpipe really didnt add much. Cold start is just a bit louder but once it warms up, Its silent.

From pure performance factor, I just drove a few kilometers after install so engine might still adapt and feel different tomorrow. But I already noticed a slight increase in power over precat delete. However the precat delete felt like a bigger step from stock downpipe. I does pull now quite well and 2nd gear TCS flickers longer into higher revs. I didnt log timing pull or acceleration numbers yet. There might be room to add more timing now, lets see. The spoolup also seems different and maybe turbo is coming on just a bit later but naturally pulls better after its going.

Overall, feels good and Im happy with it  :happy2:

If your milltek fits to stock downpipe then it should go on ok. However this means there is a slight restriction in the pipe where they are attached to each other (pipe will be stock diameter in the joint).

I have revo stage 2 so I dont know if this 100 cell is enough to keep cat efficiency being flagged up.

Whereas different pipe sections and components may manage to be fitted together it worries me that some people are happy to mix-n-match this-n-that on a remapped car. Performance exhaust systems such as Milltek, BCS, APR, are very consciously designed to be used as a whole and to perform properly without restrictions etc. There's more to it than just stringing pipework and silencers together.

If you can't afford a whole new system, how about a second-hand one?

it worries me that some people

Maybe you shouldn't worry so much what other people do? This DP seems to work perfectly, so it really doesn't make a big difference which catback you mate to it. Mainly it will just change the sound characters of the car. Its not like your changing the way engine works.

Its not a bad thing that people want to save money and not go with the unbelievably expensive exhaust options. IMHO they just dont represent a good value for money. So If someone wants to make his/her own combo, its perfectly fine and is certainly more rewarding for a person with a modification bug.
