Should I Straight pipe my F3S 2016?

[SwedishF3s]

Hello!

I am new on this site and have had my F3S for a few months now. I love loud exhaust systems and wondering if I can straight pipe my bike. But I've read in many places that I don’t need to re flash the ECU, and only need to let the bike idle. Some say I need to re flash it. And some say losing back pressure will be problem, some say it won't. I am wondering if I should still try and buy a PV3 to re flash it, but the biggest problem for me is I have no access to a dyno. Most of my bike is stock. So far I’ve only put on a K&N air filter and bought a R888R Toyo tire.

Thank you for all the info you give and ride safe xP

Just let it idle for 10 minutes and you're good to go. Will sound great even with the stock muffler

Agree with greg, Oe muffler and straight pipe will do the trick, else an cat- delete, if you worry bout backpressure, the bikes ecu, can cope with the difference without a Tune

" Straight pipe " ..... IMHO this will result in a No back-pressure situation and that's not a good thing ...... good luck .... Mike

A ton of engineering and design went into your machine and you can unknowingly diminish the potential of your spyder if you install some aftermarket items. If you want ear splitting sound that the ECU may adjust for, go with unbaffled cat delete and the 2brothers racing muffler. That's about as straight through as you can get. Even with the TailGunner muffler people can hear you coming a mile away. The cops can even hear you before they even see you. Good luck.

I run a cat delete from RLS, baffled, with an acropovic endpipe, and this produces a darker more gruntier sound. When measuring with a good Decibel Meter, the acro is more silent than the OEM Muffler with cat delete.
Straight pipe, is a whole other story - this is just obnoxious.
Over here in the Netherlands, people have started a petition which states "too loud is out", instead of "Loud Pipes saves Lives"!! Everyone their own, but I want to enjoy the sound of my bike, not to be obnoxiously loud.
Mine rumbles when downshifting (at higher rpm's). Over here, due too Loud pipes, some beautiful routes are closed for Bikers, and you will get a big fine if caught on those roads!

Straight pipe - obnoxious?? Why, sir, you go too far... (My 55 with a blown 455 olds running tuned headers, hollywoods and straight pipes was like an air raid siren in the next county!! The sheriff used to call my parents when I left the house and tell them to tell me that my ticket was in the mail... LOL!!! Good times.

+1 for Pirate - I'm putting my money into a header and cat-delete system from RLS. Likely the punisher. You can reduce the ground-shaking level of those to something nominal if you must (add baffle material in the cat-del-box and exhaust can), but having that system with a modded air box and a tuner will be all you should need (or want) unless you are considering other applications (i.e. racing).

All im looking for is to get the bike lighter, add some HP and torque and better sound

You won't gain any extra power without a tune/ECU flash. Changing your exhaust will help regarding power/weight ratio, but it won't be anything you'd notice. Look at a Two Brothers Racing exhaust as it's a full system (not a muffler only slip on).

Louder does not make you faster, it just makes you more noticeable and really obnoxious to some.

I put a Two Brothers Racing (TBR) exhaust system on my 2015 Spyder F3-S. It was definitely too loud for me even with the TBR baffle. I put a baffle in the TBR input pipe and the sound is much better with a good low rumble.

Typically, way too loud pipes are an attempt to............er.........ah...........Make up for Short Comings.
