400ex Big Gun Eco ES Exhaust

This is my 03 trx400ex with a Big Gun eco es exhaust

[@bendover1417]

this what i had on my 04 bug eye growing up brings back so many memories

[@fredmelendez4083]

That slip on sounds great.. I like it

[@traxxasrcfun]

Best sounding 400ex exhaust in my opinion

[@tristargarage]

Yeah, I have a Curtis sparks on mine now and my brother has the big gun and I think his sounds better

[@traxxasrcfun]

@@tristargarage yep. I was the first one to have one of those big gun’s in my 400ex riding group and I started a trend, there’s a few of them in my group now lol. Can’t beat the low end deep grunt they have

Perfect not to loud not to quiet

[@fukoff5658]

Thanks now I’m getting one

[@tristargarage]

You’ll love it

[@ctoutdoors2039]

Did you have any issues with it aligning up?

[@tristargarage]

I did not.

[@jsfilms7876]

What do u suggest jetting it to if I get this exhaust?

[@tristargarage]

I went to a 150 size main and left the pilot stock and it ran great, that is with the stock header pipe.

@@tristargarage thank u

[@tristargarage]

Anytime

Where could I get the rejet kit?

[@tristargarage]

I used RockyMountainATV/MC

[@premium1188]

Is it loud when you get on the throttle?

[@tristargarage]

I mean it’s definitely louder than stock but it’s not too loud

[@armanimart5438]

Do you know if this exhaust will. Fits 350 quad

[@tristargarage]

Not sure, this one was made for the 400ex. I bet big gun does make one for the 350 though

[@Jxhir]

would fit in my 300ex?

[@tristargarage]

Probably not, have to buy a pipe specifically for your bike

[@damiantafolla9828]

Is it loud in person?

[@tristargarage]

No not really, has a good sound louder than stock

[@damiantafolla9828]

@@tristargarage Is it a lot louder than stock or just a little louder?

[@tristargarage]

@damiantafolla9828 it’s a good bit louder but not too loud in my opinion, I have a 07 400ex now and it has a Curtis sparks exhaust on it and it’s too loud, but it’s more of a mx pipe

[@damiantafolla9828]

@@tristargarage so this exhaust would be good for me to drive around in my town since it’s not too loud

[@tristargarage]

Yes it should be, if your looking for a quiet option I might would look at the Lexx pipes you can get a quiet core insert for them and they sound really good

[@fredmelendez4083]

Did you jet it ..

[@tristargarage]

We did not but it needs to be, it doesn’t bog but it is running lean, we looked online and it says to go up to a 149 main and leave the pilot stock

[@fredmelendez4083]

Cool my trx 400 is all stock 05 runs great and is in clean condition. I am looking into a big guns slip on and says to run a 180 main jet. Seems complicated to me .

[@tristargarage]

Dang that seems pretty big my brother has a 07 trx400 with a Lexx mxe and a fmf power bomb header and all he needed was a 152 main

[@fredmelendez4083]

@@tristargarage I am getting one and they said to run a 180 main thats it seems like a big main jet

[@tristargarage]

Like I said that seems really big, I talked to a shop and they said to run a 150 main so that’s what I got
