well, I definitley want to do some headers, and can't really do long tube since i GUESS their illegally in the great ol' state of California,[sm=icon_rock.gif] and like mentioned by some members, it'll be a pain to swap them back to stock, plus i also have the o/r H...so dont wanna be doin to many illegal mods.

But to get back on topic, how many horses can i expect out of installing shorty headers? Sound difference?

thankyou

Shorty headers are worth about 5-10 HP in the midrange and usually cost you some power at the top end.

I have seen one test that showed a good torque gain (I think it was 17 ft-lb) around 3000 RPM, but the other big magazine review of shorties showed no such gain.

In any case, I personally wouldn't bother with shorties given the expense and the hassle for such a minimal gain, but that is just my opinion.

I suggest either getting the longtubes and taking your chances with the CHP or leave it stock.

17 on the torque is what I read too. That was with BBK's. The horsepower increase was 10 or so at 3000 but only 4 at peak. It's a big enough difference to feel in the midrange (where youre at most of the time). Still, at the cost of the install (a pro can do it in 4-5 hours) they're not worth it. If you plan on doing them yourself I say go for it. I'm putting them on my car only because I have access to a lift. In the driveway is doable but plan on a long saturday to do it. I recommend only going with long tubes here in California provided you can budget yourself TRIPLE the install fees. That will pay for the install, removal, and re-install after you get popped. Knowing a smog-guy isn't enough - if you get nailed you have to go to a referee station to get it signed off. My roomate is a CHiPy and he can't even do it. In fact, my sponsor just got nailed the other day. Lucky for him he owns a lift and can change them himself but it's still a pain.

bottom line - they're relatively cheap and if your handy go for it

I'm from Cali myself and I pulled the trigger on the kooks long tubes anyway. Our emissions aren't due for 6 years on a new car, so that means 2011 for me. By then one of two things will have happened. I will have either 1) sold my car, possibly to someone outside of California or 2) turned it into a dedicated drag racing car so it won't be used on public roads.

im not talking about smog check dude - ANY COP at ANY TIME can write you up for modified exhaust. It sucks I know. Don't let some poster from Michigan or wherever tell you a cop cant because they can and do all the time. I got nailed a while back and my sponsor got nailed the other day in 2 seperate counties. I know they help a lot and I envy you but I still say it's not worth it.

Well I guess I just need to watch my back then. I don't generally do anything to bring attention to myself on public roads *knock on wood*. I was just assuming the original poster was referring to the smog aspect of long tubes.

Where in California are you guys from? In that case they should have restriction sounds on Harleys around here now those ****s are loud as **** and still they never get pull over.
