Hi,

I just spotted a new 2-1 system from GPR! Well, I don't know for how long it's on the market but it's new to me!

You can pick the silencer type, titanium, stainless steel, carbon etc.

The system is around �500 plus VAT. Less if you opt for the stainless steel version.

The headers and link pipe look very nice to me and the whole system look like a quality one.

I am seriously considering dropping for the stainless steel one. I want the manifolds below the bike as to not mess with melting issues.

The only problem is that I have OTR/SR-Racing 2-1 already fitted, with the titanium silencer. But I am hoping I will manage to sell it.

thats how i might change my home made 2-1 system ,been thinking about it for a while,looks good.

Update, those are old pictures. The complete system comes with the GPE (Grand Prix Evolution) silencer, which looks like this:



Yummy!

A friend had this one made in Oz.

this doesn't make sense to me at all!
Why would you create a 2 in 1 with headers still going underneath the engine? a. you still haven't got more ground clearance, b. you will lose power, c. it does make a lot more sound!
It only will save some wheight + different looks

Cheers

Marcel
