R60 Exhaust Diameter

Exhaust Diameter
Anyone measure the exhaust after the 2nd Cat and resonator? I have a straight pipe welded in place of those pieces and its just a tad too loud on the highway so I'm putting a 2.25" x 18" vibrant resonator on. The straight pipe that got welded in has a slight bend in it and the resonator wont fit correctly because I am using clamps. So I'd like to put it just after that section where it's nice and straight to the muffler but I've seen some people say the pipes are less than 2.25" back there. Just wondering before I cut this up tonight and the clamps don't hold. Thank you!

So I got under her the other day and measured 55mm OD on the stock piping. The short piece that my exhaust shop welded in was 57mm. I ended up cutting into the 57mm pipe that was welded in place of my 2nd Cat and resonator, it was very thick which may have accounted for the extra 2mm but was closer to 2.25". Vibrant 1791 18" resonator slipped over the pipe nicely with the back needing just a little encouragement. It quieted things down very nicely. I think this is the perfect cheap exhaust for those looking for some new sounds. Catless DP, vibrant 1791 in place of second cat and resonator going to stock muffler. I'll try and get some clips at lunch today. Sounds great and only a slight hint of drone on highway around 2100 rpm in 6th while going uphill. Very circumstantial but thought I'd note. Butt dyno says she got a little something extra from removing those crush bends that shop had put in.

That looks like a very clean install.
I'm looking at increasing the diameter by somewhere between 2.5 and 2.75" and keep droning to almost none and hopefully get a little more push, I'm looking to keep the catted downpipe and move to a larger diameter resonator (just to accommodate the new diameter pipe) and maybe do a Muffler delete or find something find something that calls out to me

I think I would have to agree. Now that I have put some miles on this setup it has woken up a little. Still much better than the straight pipe but if I could do it again I'd go with the ultra. This is a temp solution, end goal is a 2.5" system DP back when I add the bigger turbo but this will definitely do for now. I did a blast through an underpass at lunch and it sounded great, tight and throaty is a good description.... sounds good on many levels haha

You'll be very happy with stage 2. I have a malfunctioning wastegate which doesn't let me see full boost and I still love it! Map B plenty of fun.

Hi, do you have a link as to where to buy the scorpion section you are talking about? Thanks!

When i ordered, it was on back order but they had a batch to be ready in like two weeks or so. It makes it much easier to just buy this piece than to have some one fabricate it. Here in Hawaii, I don't know of any shops that would do this without charging me an arm and a leg.

I contacted Martin Lomas at Scorpion Exhaust. Either calling +44 01773 744 123, which is what I did or email him sales@scorpion-exhausts.com and then pay them through PayPal.
