I have a 2007 Fatboy and I'm thinking about getting the SE Air filter and PCIII. Friends are telling me that I should get pipes also, and do it all at once. My brother has a stock 2003 Fatboy, and my 07 with the stock exhaust is definately throatier than his, but no where as loud as some I hear. I also have a sportster, that I bought used, with the SE pipes, and Air Filter. That little bike is so load, it sets off car alarms in my neighborhood and I think its just a little too loud for my tastes.I'd like a compromise between loudness and performance. The Screamin Eagle slip ons say they are legal in all 50 states, does that mean they are extremely loud?

On top of this, I keep reading about EPA restrictions, noise control violations, modifying emission systems - Do I have to worry about any of that?

Thanks for all your help!

Actually, the new SE slip ons are so EPA compliant that they're not much louder than stock, so you might like them...I've got SEII's on my '07, but they're an older racing set that H-D discontinued when the EPA started getting on their ***.
Yeah, I can blip alarms if I get into them, but just deep & throaty normally. And a PCIII or another good fuel management system is definitely needed, as new bikes run real lean from the factory to meet EPA regs...and when you start shoving more air thru, they get leaner & hotter...with a good tuner the bike runs cooler and makes a night & day difference in performance.

 

I'd put a set of full pipes why waste your money on slip-ons then wish you had gotten
something else. Not mention it would be more comfortable for your passengers right foot

I started off with the Rush 1.75 slip ons, and the sound was about perfect for me. Not too much louder at idle, but much deeper. At WOT, they would bark pretty good. The neat thing about Rush is that you can easily change the sound with different size baffles. A couple months ago, I finally went with the V&HDouble Barrels, mainly due to my girlfriend always melting her shoe, but also for larger detachable bags. The sound is comparable, but the Rush may sound a little better......

BTW, I still have the Rush slip ons.....I'll sell them cheap!

I have the Rush slip- on mufflers on my Deluxe . They sound really good too . Kind of a growling type sound . It's cool . I checked out the website for them . It says they guarentee you 5 h.p. with them . Dunno if that's true or not , but it sounded good . ................Kev

I have the Rush with 2.0 baffles and love them also.

 

if your set on using slip ons, go Rush... but you should look into full pipes. there are so many options, styles, soundand performance differences with a full set.

 

I have the rush slip-ons with 2.25" baffle, I LOVE the sound![8D]

My wife has the Rush slip-ons with modified 2" baffles on her 07 FLSTC. We made the necessary modifications for a deeper tone with out being louder. She likes them. I have the same model bike with stock pipes, and it is OK for me, but she likes the sound of her pipes. She also has the AC, SERT, and her bike is faster than mine. Tomorrow morning it will be 25 degrees out and she will be up early and riding. Don and Pam
