Hi Folks

Any opinions on if an STi8 standard back box would fit an MY00 classic turbo which has a TSL center section? - I guess the mountings would need some modifying but would the pipe diameters be compatible?

Is this worth swapping over as I already have a Prodrive backbox fitted? i.e. could the sti8 stnd box be more restrictive - bearing in mind the sti8 is being replaced with a PPP version.

Cheers

It will fit, but the STi 7 and 8 backbox is very restrictive. The pipe going into the BB is only 50 mm in diameter, compared to 60 mm for the rest of the system.

Keep the Prodrive one!!

A picture paints a thousand words.

I'll stick with what I have.

The thing that makes the STi box so restrictive is having all those green and red neon arrows inside!

The Prodrive is still straight through, albeit quieter and arguably a little more restrictive than most striaght through boxes.
