Ok so on my car I had a full 3" japspeed decat system turbo back and just bought blitz nur spec r center and back box thinking it would fit.. Now there different sizes lengths pipe to japspeed do won't line up with down pipe... Anyone else had this problem?? What down pipe do I need? Cheers

 

Car is 2005 blob sti aswell

 

To save a lot if messing about if you plan on keeping it just get the centre section cut down and re welded to suit, would be about £40 max from an exhaust place, If you decide to sell it sell it as a full system

 

Yehh going to get it cut down I thing gaz.. Up Witt rib at Stella motors after Xmas. So will ask him to do it mate. Then hopefully get over to one of the LADS meets in new year

 

Cobra DP will fit

 

You sure you don't have a classic Nur spec system as they are a different length to the newage 1s.

 

Nope came off a 2003 blob mate.. It's the length of down pipe that's stopping it.. Guna be cheaper to cut it down then but cobra down pipe

 

Is nur spec not 2.5 inch donut/flange then going to 3 inch section? You do know every mot time you will need to go back to a catted/sport cat downpipe

 

Yep got 11months left in MOT. It's 100% nur spec r cat back system

 

JDM System is different length to a uk one.

 

It came off uk model mate
