New Exhaust and Backfires

Hang on, if it's a 3/4 system, did it replace the rear downpipe? CXould be you just need new gaskets at the "breaks"...

No - rear downpipe hasnt been touched. The new exhaust just slips on to the downpipe from the rear cylinder and clamps up to it.

Without the Power Commander and full dynotune, there is a Suzuki tool that remaps the ECU at 3 sites. I was informed of this when my can/ K&N was fitted. Not as precise and exact as a P.Com. & dynotune with over 100 map sites but still required when "rebreathing" the engine by way of new exhausts etc.

My mechanic road tested the bike and one of the things he looked for was popping and backfiring.

Done no remapping at all. Its all still standard in that department. Also, not fitted a K&N etc either.

If I do need to have this Suzuki tool thing done, is it a main dealer job or can any bike mechanic do it? Whats the cost involved?

Ah right, it's a K3 isn't it. So there's not a gasket where the old pipe came off and the new one joins?

My guess is you need a Suzuki bike mechanic to do it as they are most likely to have the Suzuki remapping tool.

Cost - costs nothing to ask them if they can do it and what they will charge if it is required. (My cost was part of supply & fitting of the Scorpion - $500 NZ dollars total plus $200 NZD for 6000km service) A bargain INMHO.

Nope. Even the original pipework just clamped on with an allen key type bolt. Pretty esay really.

Bugger! Mines just had its 6km service a couple of weeks ago too! Oh well.... Cheers Shooter

Ah right. The '00 pipe is the same at the rear cylinder (a short pipe with a gasket, which attaches to the actual downpipe by a wee allen bolt) but there's a gasket where it breaks at the bottom, near the collector box.

On the 03 pipe, its all one welded unit as far as I can see.

Whille your on the subject of exhausts as anyboby tried an Evo Blue Fame and if so are they any good

Then how does a 3/4 system work for it? Maybe I'm being dense...

For the original bike, it's in 3 bits- there's the rear downpipe, can, and collector box in one part, the tiny wee bit that goes at the top of the rear downpipe (which is where one end of a 3/4 system would go) and the front downpipe. Usually a 3/4 system would replace the whole back half and retain only the front downpipe, but there has to be a link where the front downpipe and the rest of the system somewhere, and on the old bike there's a gasket in there.
