Hi peeps,

 

Will my 2.5" backbox flanges bolt straight onto the standart 2" pipe on my TT or do I need to get some pipes from the Turbos back??

 

Bit lost and think I made a booboo just buying the back boxes.... :death:

Normally buying a catback, will have the correct size from the cats. Back boxes only you will need to get a collar fitted to slide over the old pipe. Either welded or U clamps.

So I need to buy a cat-back 2.5" pipe?

 

It was MarkyB's old system, I thought just the rear boxes on this picture would fit onto my standard setup... Obviously I was wrong and needed the complete thing? *wonders*

 

Do the flanges not match up?

Not attempted to take the exhaust off yet bud... But I measured the standard pipe before the flange and the piper after the flange on the new back's...

 

stock before flange was 2"

back boxes after flange was 2.5"

Would the sections in this thread fit?

If so, I will buy it!

If you have enough length, i would cut off both flanges and get a coupler tube with a couple of U clamps on each, job done.

Before i went completely stainless, i bought 2 back boxes off ebay and had them fitted in with a coupling tube and worked a treat.

They would mate, but before you have to spend a load of money unneccessarily, try below

ok bud, thanks ;)

I got the standard boxes off Groover... the 2" flange is not lining up with the holes on the new 2.5" backboxes ='0(

 

Do I need the downpipe all the way from the turbos back?
