I've finally had my exhaust system and PCE fitted :banana:

Mine is the 2.25" system without pre anything :shock:

I haven't done many miles in it yet but there is a definate performance improvement and the sound is awsome, a lovley deep growl which builds around 3000 RPM.

I have heard a few pops and bangs when on overrun but I had this with my previous system anyway. Now it's only louder :shock:

The wastegate was ported at the same time, so no overboost problems for me :-D so far!

It was all expertly done at TrackVRoad my local TVR and Lotus Specialist. The guys there said it looked a quality piece of kit and fitted really well.

Belated thanks to Garry and his team at Piper

PS. Does any one know what causes the pops and bangs on overrun and any way of reducing them or getting rid all together?

It's unburnt fuel expoding in the exhaust.

Thats what I have been led to believe.

I get it too. :-D

make sure your timing is spot on the minimise the popping, but some is normal, id guess the extra silencer would quiten then down a fair bit.

DHL via http://www.transglobal.org.uk is still saying £54, but I thought DHL was kaput...
FedEx "World Express Service" is £84 via http://www.parcel2go.com
UPS is well over £200.

I'm due to speak with the nephew today and will post more info.

Ever hear back from him?

Bottom line is we should really try and figure out a cost-effective shipping method for this. Piper surely wants to sell us Yanks some steel. And it certainly come in handy with the folks buying the S2 wheels, etc.

Andy I used to get the popping sounds all the time when ever I backed off .

When I checked the timing I found that it was out a bit so I just reset it and now I don't get any popping sounds at all :D

Hi Andy,

I have it fitted as well and it s true that the sound is great... but the wastegate not ported so far (pretty annoying , especially during overcoming...).
Do you have an idea of what it costed you at the garage ? I m not feeling like doing it myself.

Cesar

It cost me £300 plus parts ( i.e. gaskets ) plus VAT. In total just a touch over £400

The vast majority of that being the labour to get the turbo off, port the wastgate and refit. They did say it took a bit longer than the amount of labour they quoted me for!

Hope this helps

After a few months of running the Piper..... a bit more of an update ...

The 2.5 piper gives the occasional Pop, but it also bangs (It's loud as well)...Saying that It takes alot to do it, the first time it did one I nearly sh1t myself...

Flash backs of Stig Blomqvist in an his S1...

If you like quick bursts of harsh acceloration followed by even harsher brakes... you'll get the bangs

I find for the best "Pops" is 2K revs and inertia driving the engine...

Still awaiting the time to fit the "Stiffy"

If you have a problem, if no one else can help, and if you can find them, maybe you can hire... The N/A-Team.

Okay.
Piper 2.25 with sports cat'. And Piper P.C.E fitted to an otherwise standard '94 S2.

NO BOOST CREEP!

Boost guage has gone from a rock steady 0.5 to a healthy and far more responsive and quicker winding 0.65-ish... The car feels transformed, much quicker and far smoother. Only done a quick drive but boost creep/fuel cut isn't present. Let's see what the future brings...

Wow have been looking through this topic and very impressed with how this has come along since it started, and also Pipers dedication to the job, so much that I am cancelling my order with Peco (cybox) to order the Lotus Elan Turbo - 2.25" Exhaust system (without sports cat or silencer) for my S2.

You will be happy. Fits great, sounds great and is getting even better as time goes on. Really deep burble. It looks good as well. Plus it does the job it was made for. M&A

2.5" with no restrictions. Cracking piece of kit, great sound and easy to fit (according the the local mannie) instant increase in performance, boost creep that will need to be sorted .....someday! :banana:

Today a section of my current 2" system became split and un-joined. Therefore I have decided to go forward and actually order a Piper exhaust to be fitted asap. Problem is there are so many varying views and advice to take in. I have an S2 and think that the 2.25" system is perfectly adequate but do I or do I not pay over £100 to get the built in sports cat or just risk it with just the Pre cat and also save money? It's not like you can get it tested and if it fails, send it back and order the one with the cat. I need to order this tomorrow and am un-decided as to which is the best option or whether playing it safe is the best.

Thanks in advance for advice ...

Emissions regs changed for cars registered after June '96. If your S2 was registered before then, it should be ok without a cat.

On the other hand...

A cat will not allow the exhaust to flow quite as freely & may make the difference between overboost & no overboost.

Faced the same dilemma when I bought mine. I went conservative cos I'm not chasing the last n BHP or db. In fact I dont yet know if its paid off cos I've not had my next MOT yet...but I'm hoping my decision to use the 2 1/4 with Sports Cat will see it sail through (despite also removing the pre-cat and porting). Of course if it doesn't then the rest of you guys with 2 1/2s and/or no sports cat are in deep doos ! :-D
