Termi GP Shorty

Not fan of shortys, but looks like alternative to Akra

Love the fact the Spanish circuits still have no noise limits... This would be ear splitting down the pit straight

- Alex

I prefer that to the Akra

I can't make my mind up on what full system to go for an the Gen 4. I really like the look of the Austin Racing systems but heard that they might cause powder drops? Any info on that? Failing that the carbon Akra looks good if not a bit safe.

Not bothered about noise testing and I do like a loud exhaust.

Termis ive always associated with ducatis....i quite like the sc project

I quite like the SC Project too, because to me it doesn't quite look a shorty and something between a full length and shorty, so a 'middy' I think.

Then again, I do like the full length titanium Akra as well. Will get something once this CV does one! Grrrrr

Arrow

Arrow now offer a good range of exhausts for the Gen 4.

my gen 3 SC Project isnt really a shorty but shorter than most aftermarket cans its quite loud especially when changing gear with pops and bangs ,I wouldnt want anything louder tbh

I had a look at SC project but they don't do any full systems that I could see

what about an arrow system ?

Excellent systems, brilliantly made and well worth the money. If I hadn?t already bought an Akrapovic system then I would have purchased one from Arrow.

There's another option; Spark.it. Mate has one on his 'blade and it's hilariously loud. Like 110+db. Great build quality though.

Arrow would make most sense to me for the budget conscious. Full TI for the price of an Akra Stainless.

Can you share the pricing ?

From what I see Full Arrow SS is marginally cheaper (100 gbp) vs. Full Akra SS from Omniaracing.

Whats the point buying Arrow - no idea.

The Spark systems are seriously good quality. I don't fancy the Arrow cans for the Gen 4 even though I'm happy with my Arroe system on the Gen 3

Need to be careful when looking for a full system for the gen 4. It?s got 4 lambda sensors and the Spark systems only come with 2 bungs so it can?t be run with the standard electronics.

Whilst not plug and play you can add more if required. Guessing they expect mapped machines that only require 2.

That?s what they?re saying, must be used with a race ecu

From what I understand, decent fuel maps RS2E or M RCK only use 2 sensors (front), the other 2 can be blocked off.

You don't need "race" ecu, you just need to have fuel map in ECU.

I don?t doubt that.

Was meaning if people wanting to fit the full system without adding RCK and wanted to use the standard ECU

you dont need RCK to change fueling. You just take the bike to any Dyno that deals with BMW, they can just tweak your ECU with software.
