Finally got to the bottom of this issue come MOT, and it was actually a leak in the cat back exhaust. My scorpion resonated cat back had split around the resonated section. I'd assumed it was my own dodgy DIY but my work on the car had nothing to do with it. Scorpion were great about it and sent out a new part, so that was bolted on and passed MOT no fuss. Can't fault them for their service. MPG issues are gone now too, surprisingly.

Yeah, the mpg issues seem to have settled back down now, I'd say it's marginally better than stock. So that's a bonus, just the leak to sort now at the doughnut. My wallet is in enough pain as it is 😂

Glad to hear I'm not the only one with the issue! Thanks for the info, did you use the penny washers to hold the spring in place with the longer bolt? Looks like that would be a good route to take, as it is really difficult getting the standard bolt and spring on. Thanks

Another update, after installing all of the new consumables, gasket, properly sealed slip joints and new spring bolts. Night and day, the Berk pipe sounds fantastic paired with the Scorpion resonated catback. Love it. Thanks for all the help on here. Only issue I have is that I just couldn't get one of the spring bolts onto the frontpipe/catback around the Doughnut gasket. I ended up removing the spring, so I only have one bolt with the spring there. Meaning to get it done properly when I have more time, but any tips on compressing the spring to get the nut on the bolt? I almost did it twice but the nut pinged off as soon as I released the pressure slightly.

That's perfect, thank you!

By the way, does anyone know where I can get a replacement Cone/Doughnut gasket for future reference? I've checked eBay, but not 100% sure about the sizing or part number. Any help much appreciated, thanks.

No the doughnut gasket was fine, I made sure to reuse that. It's the Scorpion exhaust. It is connected by slip joints and the front joint ahead of the resonator is leaking. Going under the car later to try and adjust it. It could have been the cause of the sound from the Berk, so may end up putting that back on at some point.

Tried the old stock frontpipe and found the source of the leak. My catback was loose at one of the joins, that may have been what was causing all the noise as the leak was before the resonator. Likely getting some sound leaking prior to resonation with the Berk pipe. Happy to have found the issue.

Thanks for the advice, I'm going to test running the stock frontpipe on the car again and see if I can eliminate that from the equation. I may have made a mistake in buying the frontpipe, in which case it may be up for sale on this forum soon.

I've just recently installed a Berk high flow catted frontpipe and my mpg has gone through the floor. I can watch the needle move when I am gunning the car it's that bad, whereas before on the stock frontpipe I saw no such increase in fuel consumption. Is this normal? I noticed an increased eagerness to rev, but I don't think it's worth it if I'm going to need to be refuelling every 5 minutes. Plus there's a hell of a lot of resonance that I wasn't expecting based on what I've read online. I have a resonated Scorpion cat back for reference and the manifold and overpipe are stock. Anyone else have similar experience, or should I be concerned that something else is wrong with the car and the frontpipe is just a coincidence?

Yeah they are still available

Price drop to £150 ONO

I'm selling my old Valenti Taillights, the nearside (left) light is in great condition but the offside (right) has had some condensation which is now dry, but there is water marking inside. Also, in an attempt to drain the lights and stop water build up, I drilled the base of the light, but it wasn't the prettiest job. See pics. The nearside has original gasket, but the offside has a thicker homemade gasket. These are the sequential indicators, too. Looking for £150 ONO on these. Located in Exning, Suffolk. Ideally collection, but can sort postage for a fee.
