Pipewerx 3" Exhaust Down Pipe High Flow Sports Cat Help

Thanks again AJP - the stage thing makes sense, it is just a number as they are custom maps. I never thought of it like that.

I've just emailed R-Tech for their advice and to book in for the 'tweak map' - I'll let you know what they say. They'll probably call it a stage 1+ map I presume?

I'd say if you were going to get an uprated pump as well as the BCS you'd be somewhere between 1+ and 2 in R-Tech terms. But again, no point labelling it with a number!

I'd imagine a car with an aftermarket turbo back, aftermarket HPFP and a standard inlet would be a much nicer beast than one with an aftermarket turbo back, aftermarket inlet and standard HPFP.

If you're just doing the exhaust then map tweak without a HPFP upgrade, you should see a reasonable increase in power across the rev range, maybe seeing the best increases at mid-high revs, where the standard downpipe and cat would bottleneck the flow. Again, don't look at the before and after peak hp figures to see what you gain, look at the extra area under the curve.

Exhaust was finally fitted on Wednesday and boy has it made a difference. The first thing is the sound....absolutely awesome! Cannot ask for more. And so glad I went for the Powervalve system....I'm sure I would have regretted getting any other system!

Now booked in for my re-map tweak at R-Tech a week today. Then leaving the car alone for a while and just gonna enjoy it......

Brilliant Nige - thanks for uploading the pics!

I was gonna add them on here but was struggling to.

By the way this now means I am selling my stock OEM system, including downpipe and cats.

It came off my car at 66,750 miles and is in very good condition.

Please contact me for any further information.

Did you get the map tweeked to suit the BCS?

[rashg60]

Yes mate did get it done.

With the tweak it is now running at 273bhp and 347 lb/ft torque.

With a big mod like the exhaust, it makes sense to get the map tweaked to suit/take full advantage.

How's it running at the minute Rash?

Mine's in with Steve at Statller in a week. He did a quick scan and there's a fuelling fault (as I thought), but he's going to log it properly to see exactly what the issue is. Said it could be the LPFP.

I'm bracing myself a bit. Could also be an injector causing the dodgy cold idle, or a coilpack. And the fuelling error could be a worn/dead cam follower causing pump issues and worst case, camshaft damage. It had a new follower about 6k ago though, so fingers crossed.

I did pick up a Loba pump a few weeks ago, so that'll be going in regardless. Best case scenario is that is all it is; standard pump struggling and simply causing fuel cuts, and the Loba sorts it. Doesn't explain the idle though... as far as my knowledge goes!

[rashg60]

To be honest, mine is running very smoothly indeed and very quick. I think it was just having a bad day that day. I now take it out around once a week to give it a good thrashing and that sorts it out. I hardly drive it during the week though, so could just be that.

Please do keep me updated about your issues, just in case I experience them also. Fingers crossed I won't have to. Been lucky so far with the clutch etc.

PS - I ordered the Edition 30 front splitter (non original - was recommended by a few peeps on here and I've seen it in real life and it does look good). Anyway got some quotes for spraying that and the side skirts. Once they are done I'll put the bumper on in one go. Don't want it looking odd with just the bumper.

[AJP]

I'll let you know how it goes mate. I'm probably over thinking things in regards to what could be at fault, but I suppose it doesn't hurt to be realistic about potential costs. Glad yours is running well anyway.

Looking forward to seeing some pics with all the bits painted up!
