just ordered a blitz nur spec r for my04 wrx, i also have a 3" sports cat to go in front of that....

noticed the nur spec r shrinks to a 2.5" neck to fit the standered cat. is this going to be a problem when attaching to my 3" pipe???

please advise

When you say 3", I assume you're referring to the sports cat flange's bolt-holes point to point spacing, yes?

If so (and I might be wrong on this) but I reckon your Nur Spec R's 2.5" centre-section flange WILL mate with the 3" downpipe flange... BUT using a 3" flat 'diamond'-type gasket, rather than the normal donut/cone type wire-wool one (assuming New Ages still use the wire wool one anyway?).

When you receive the Nur Spec R, measure the point to point distance of your centre-section's flange holes... I'm certain they'll be 3" apart, so should bolt to the 3" flange of your d/p okay.

To put it simply... For joining centre-sections to downpipes, all bolt holes - for either 2.5"- or 3"-bore pipework - are spaced at 3". If you are mating 3"-bore to 3"-bore, or 2.5"-bore to 3"-bore, then use a- 3" flat diamond' jobbie. If it's OEM 2.5"-bore to 2.5"-bore, then use the OEM-sized donut... I think(?) LOL.

 

ive got mine matted to a 3 inch dwnpipe no probs ul love it m8

 

straight foward matched up????? just bolt and go?

 

it matchs straight up no problems had it on my 3" for ages then got the 2.5" cut out cost me £40 then its a true 3" system
