Dinitrol iirc. I don't recall being offered a clear coat as that's what I would have gone for.

Cobra definitely don't do a jdm downpipe, I've asked them

Bugger. Thanks. Yes, JDM twin scroll decat pipes are a bit sketchy

H&S are looking favourite then, and I'm going to speak Milltek tomorrow about the d/pipe

The miltek one I got had to be drilled for rear lambda the hole was in totally wrong place
Then on start up the weld was leaking had have that repaired on a brand new front pipe
Was not impressed

Infinity at Bristol do whatever you want for about 25% cheaper than H and S, very prompt at answering questions, only difference is that they make the exhaust on the spot, specifically for your car, and it doesn't leave until it is perfect.

Result

Had the resonator removed today and the difference has made the sound pretty much exactly what I was after

Made what would be called a definite difference, and for me what was too quiet before, is great now

Pottering and NSL cruising is quiet. Any use of throttle lights things up with certain rpm's louder that others and boost makes everything better/deeper etc

Car in for mapping Thursday, so may change a little more

Who is mapping it? Hope they sort any "stumble" at around 3000rpm. 3port boost solenoid makes it much easier for mapper to control boost

Did you get a mid pipe without a resonator or cut the Milltek up?

There is a stumble indeed at around 3K - what makes you ask HG - common issue?

I went to a place that makes exhausts and they removed the resonator box from the pipe and put in a replacement (straight patch pipe). I got them to flange up the ends of the resonator section so it will easily go back in if desired (but it works so well I can't see that happening)

I'll be doing the same at some point. So thanks for the RnD

Glad it's helpful

Very recommended. I'm well pleased with the result.

You could just as easily buy a Miltek centre pipe, which costs ~£90 delivered and it's an easy diy swap

Had I not been so impatient, and had a re-map booked 2 days later I may have gone that route. As it was both were the same money and now I only have to store a small box and not a long pipe with box

Google "grb stumble" on American sites; Subaru changed the fpr on the hatch, and added dampers to the fuel line. They then used the fuel compensation tables to smooth it out, but upping the power makes it worse. I think it can be mapped out by spending time on it; solutions with varying degrees of success involve longer fuel line, removing dampers and an uprated or Hawk fpr, or parallel fuel rails for a certain fix.
I would be really interested in feedback from your mapper, as I am still humming and hahing about mine. Did Darren say who mapped it initially?

Thanks for that info HC. To be forewarned is to be forearmed (for my mapper tomorrow)

The car has been mapped twice now, firstly at Surrey RR (presumably JGM) and then end of last year by Andy Carr
