will carb rejetting be needed

[ps4020]

I would like to gut out my exhaust on my 2004 rx 1, Will I need to rejet my carbs? And will it make my exhaust a lot louder? and what do I have to remove to get exhaust out of sled? any info would be great,
thanks,
Todd

Yes rejet, no, no extra power. Louder yes. Illegal? In most places.

Based off of gutting my 03, yes you will need to rejet. I had to go down, I believe two jet sizes.

Sound level is not too bad. It definately sounds closer to a super bike, however, it isn't like going to a Vance and Heinz level on a bike.

I don't think that you would get busted for loudness either unless you were bleeping the throttle hard through town.

Like stock, it begins to lose noise above 70/75 and go into silent mode.

Gilbey, you down sized the jets, I thought there was already a lean condition at mid range, any thoughts on this, just wondering.

I was very concerned...and still am at times. Color on the plugs is good, warranty is done but that's what I had to do to make her run well.

I only put a 1000 miles on last year. So I think another 1000-2000 will tell any long term effects.

It's a risk, but the 1000 miles it ran well last year.
