Here’s a sound clip of my Sparks Racing X6 Race Core Stainless Steel Exhaust System on my 2001 Honda TRX400EX (Bored to 426CC) (Fourtrax / Sportrax 400EX). It’s built in the USA (AMAZING QUALITY) and here’s the description from their website: The Sparks Racing X6 Stainless Steel Exhaust system is the ideal exhaust system for any application because of the power gains it produces through the entire power curve. Our exhausts are complete systems, not slip-ons, because we’ve found much more performance with designing a complete system rather than working with the limitations of the stock head pipe. Some aftermarket exhaust systems are able to be used as a slip-on or complete system, but the problem is they’re still limited to stock diameters where the head pipe and rear section come together. We have spent countless hours testing on the dyno, on the track with Pro-level riders, and at the drag races to insure the most performance possible out of our exhaust systems. This exhaust system is offered in both the X6 Race Core and X6 Big Core systems. The X6 Race Core features a 2” outlet diameter which offers the best all-around performance and can be configured with a spark arrestor and quiet inserts. The Race Core system is about 102db using SAE testing guidelines. The Big Core exhaust system houses a 2.25” outlet diameter which offers more top-end performance on built engines. The Big Core is about 110db using SAE testing guidelines. The Big Core cannot be configured with any quiet inserts. A spark arrestor can be installed in the Big Core system, but the Big Core was never intended to use a spark arrestor. Running a spark arrestor in the Big Core will drastically shorten the arrestor’s life span..

[@BillWilliamson420]

my dad has one they are really loud sounds awesome

[@rolandofigueroa3142]

How do u measure the canister to know if I got the race core or big core

[@yoyohipptyyo8760]

@@rolandofigueroa3142 the main is a 2.25 and the race is a 2 inch

[@DownAndDirtyOffRoad]

Same exhaust I have. Great sounding.

[@LegacyCraftworks]

There's nothing quite like it!👌

[@mccann19871]

I have one on my 400ex it sounds awesome.

[@LegacyCraftworks]

Music to my ears! 🎶

[@teamwoodswarriorsracing2004]

The big core is a 2.25" canister core while the race core is 2"

[@Drain09]

What clutch cable you running? Mine was routed through stock header but on aftermarket rubs/melts. I need to reroute

[@LegacyCraftworks]

I was running a 1992 Honda 250x clutch cable (Stock). It's longer and you can reroute it differently👍

[@valentillo91]

I put the same one in my yfz450 but after driving for about 7 minutes I turn it off and it does not turn on until it cools

[@LegacyCraftworks]

Hey, did you rejet ? If it's fuel injection it might need a different tune. Sorry I know very little about the yfz450's.

[@cass8144]

You need to get it tuned if it's a fuel injection yfz. Your quad is prob running to lean

[@LegacyCraftworks]

@@cass8144 Thanks for helping out 👌

[@LegacyCraftworks]

Running lean usually causes the engine to overheat (To much air and not enough fuel)

[@cass8144]

@no use for a name stock quad engines run lean so you need to bump up the fuel jet becuase lean=to much air needs more fuel. If you are running rich you have a bit to much fuel but your motor will run cooler

[@davidblum_]

Is the big core louder? I have a sparks exhaust but it doesn’t have the bolts yours has on the tip

[@davidblum_]

Not sure if I have the big core or race core

[@LegacyCraftworks]

@@davidblum_ I'm assuming the big core is louder, but I never actually heard one. This one is the race-core; I was told the Big Core was only useful for drag race and TT. Maybe it's a bit different because I had an early model from 2011?

[@miguel.3.]

What are the jet sizes

[@LegacyCraftworks]

Sorry, I don't have the 4wheeler anymore.

[@Tice55]

Louder than dasa?

[@LegacyCraftworks]

I don't know, I never heard a Dasa in person.
