I need some inlet trumpets for my TB's.
The TB's are GSXR750 fitted to a 2.0l Zetec.
I am going to be using a panel/sausage type filter to begin with but will eventually end up with an airbox of some description like the Pipercross 600 airbox if this makes a diference on the trumpets.
Will the standard ones from the bike which are two different lengths be suitable or do I need all the same length?

Cheers
Stu.

I recently bought a 750srad inj. airbox (98ish..?) on the bay and was pleasantly surprised to find that the trumpets were all the same length...

in orignal motorbike format believe the trumpets are of differing lengths to get a better spread of Torque over a wider rev band, think in most car formats length of trumpets seems to be more decided on praticalitys on what will fit within filter/air box and not be to close to the filter element rather than over all port length, hopefully in next couple of months im getting my Zetec on Emeralds RR and will try out all combinations of trumpets to see effects.
