hi guys can u please help me which muffler should i buy.

pro circuit T4 ot yoshimura trc. i will still use my stock headers . i only what to have a louder sound. which one is louder the pro circuit T4 or yoshimura trc


thanks

If the sound is all that you want to tune, try altering or removing your baffle. If that satisfies your need then you save a lot of money. Try not to get too loud. If you take out your baffles, keep them handy for sound sensitive areas. The db's go up to about 96 and it gets "throatier". You may have to adjust your jetting as well (same if you go after-market).

Well, I have the T-4 on my 450x and the Yoshi on my girlfriends 250x. If the price was the same I like the look and sound of the T-4 better than the Yoshi. But I really like the Yoshi as well. It really makes the 250x wake up and it sounds great!

You can't go wrong with either one! IMHO!

Instigator....I think I see Yamaha blue at the end of your 3rd picture!!!!! BUSTED!
Is that a pw50?

Nice graphics on your bike!

Now on to topic.....I have two friends who swear by the White Brothers exhaust with the stock headers. And I have heard nothing but great things about the FMF Factory 4.1C

Thought I would add some more confusion into your choices!

Yeah, yeah, it's a pw 50 but it is great for teaching because it is smaller than the CRF50!

My 3 1/2 year old has ridden it solo over the new years holiday check it out!

This is Logan 3 1/2 years old!

sir instigator

do u have any idea how loud is the yoshimura TRC compare to procircuit T4 ( in DB)? how about the stock muffler with out the baffle compare to the yoshimura TRC. i want a louder muffler .

thanks

If you want louder go with the pro circuit. I do not know what the DB levels are

great shots..your boy is tearin it up
if I can figure this out I will post a photo of my 8 year old nephew on his crf50.. he is off the trainers now and is begging his dad and me to open up the throttle for him....I'm soooo proud



Ps he has all the protective gear..he is in the sneakers cause we were done for the day and we were loading up

Personally I would like to choke people with really loud exhaust systems. Hopefully you are just going for a little louder. Loud does not always = power. Frequently people get less usable power with the loud rear pipes. The stock pipe is ridiculously quiet! Check this link http://www.rickramsey.net/CRF250Xmymods.htm#diffuser it might make your stock pipe loud enough but still WAY below offensive. You never stated what you wanted to achieve with a louder pipe.

I couldnt agree with cowboy more.People who WANT more noise are choking out our tracks and giving our awesome sport a bad name!

I say... Runem over and stringem up boys!
