HMF or Two Brothers Exhaust 400ex

[BUBBA Livesay]

i was thinking about getting a two bros exhaust but i dont no anyone with one on a 400ex. I like HMFs but they are a little loud. i have never heard a two bros. i ve narrowed my choices down to these two any comments

Two Bros has a P4 power tip available that quiets there pipe to 93db. I'd go however with HMF, they are built to last and made with quality. HMF has quiet-core exhausts too.

i have rode a bike with a hmf and it sounded awesome! and it made quite a diffrence from the stock setup. you no anyone with a two bros exhaust if so do they like it?

Yeah I do his name is Chris, he has one on his EX and it's quiet but he isn't real impressed with the power gain though. He is switching to Supertrapp.

go with the HMF. and get the quiet core if its 2 loud

If you live in a sound sensitive area the HMF may be too loud, even with the quiet core. We live in a subdivision and my brother has an hmf, and yesterday he just got the quiet core (hoping it would quiet it down a lot), and it still seems a little loud for our liking. Just something to think about

I've heard nothing but good things about the HMF. Except for them being loud, but a Quiet core can tone that down to 96 db. Great gains and sound.

I think i am going to go with the hmf and get a quiet core for around here at home. i let you know how it works out. gotta wait for next paycheck though:p

You wont go wrong. Make sure you jet it afterwords I did a K&N / Dynojet stage one...it Rips and sounds great.

My only regret...If I had it to do over again, I would have put even more money into the slip on. I got the brushed alum...and it looks great... At the time I didn't know how I would like it. Now that I know, I would have paid the extra and when with the sport series...and a fancy color... The red w/graphite look amazing. Good luck! Ill post some pics of mine. I finally got back where I could ride it for a solid week.
