NEW EXHAUST

[Spook]

Ok .. I've made some big changes to my toy ..04 XB.
Air intake and a "custom" hand made exhaust .. made a dual exhaust system ... ummm .. because I wanted Too !!!!
It still runs really nice .. maybe a little rich ??
It back fires on hard deceleration .. but it always did ...It's just that you can really hear it now !!
My question is should I get it remapped .. dyno'd ???
or will the computer figure all this out after "the 50 miles" to it's own satisfaction ?????

^[up] the EBR ECM won;t help you because you have a custom system. "theoctopus" is a member here and the "Tuniversity" is his brain child. I haven't had him work over a map for me, but I can higly recommend him from other's responses.

Agreed we need to hear this and let us know what you did to it.

Yes anytime you alter or mod your bike there will be some different sounds and Decelleration Popping is normal for a untuned Engine with a Non Stock Exhaust. Especially with a Stock ECM OR Race Ecm tuned to a Exhaust to match. Did you Straight Pipe the Bike with Duals? Or is there a Dual Exhaust with short Mufflers kind of like a D & D pipe set. Keep you a set of Extra plugs around in case it runs a little Rich. I bet it sounds off pretty good. Ride Safe.*Jimi[cool]
