Just order Kerker exhaust supertrapp 2:1 and a SE air intake will I hurt the bike by me putting them on now and get a tune and dyno in a week or so ? It a Californian bike

 

I'm not a pro, so I don't know if it'll hurt it BUT I'd wait to ride it, until I got the tune/dyno. If anything, I'd think it wouldn't run that good without a tune. But I'd wait.

I'm sure you'll get an answer soon from someone who knows.

 

I'm not a pro either but I can tell you from experience that it won't hurt a thing and probably won't even run that bad as long as you leave your 02 sensors hooked up

 

What he said, won't hurt anything at all

 

question if your in california and removing the cat doesnt that risk other issues. I thought cali was really strict on smog and emissions?

 

Yo should be fine. I rode mine for 1000 miles with V&H Staggereds with SE stage 1 and no issues. Then the dealer loaded a tune on it. What a waste of time that was. I recommend buying a tuner and having it Dyno tuned.

No you won't hurt anything, but it will make the bike run leaner than it is already.
