What exhaust? 2004-2005 or 2006-2009 trx450R hybrid

[cartman0102]

Hi all,
I am currently building a hybrid.

Frame laeger TRX250R CR500 engine with CRF 450.


Sorry for my bad English, I'm from Belgium.

What full exhaust should I choose?

I took a TRX450R model, but it differentiates 2004-2005 and 2006-2009.

What is the difference?
With or without a kick?

Or it is because the sub frame?

For CRF in laeger narrow, what should I take?

Thank you in advance.

I post pictures when finished.

You'll probably want to go with the 2004/05 pipe. However you may want to consider going with the CRF header and TRX silencer.

Here are some pictures to show the difference.

TRX pipe and waterspout on CRF motor - not much clearance. You can pick up an american dream waterpump cover to fix it, or go with the CRF header.

CRF header but needs a mid-pipe to join to the TRX silencer.

How it should look together with either pipe.
