If you have a choice ESR or Sparks

[yellowex01]

Which on would you get The ESR or the Sparks? There is only $36 seperating the two so money isnt a concern.. This would be mainly a mx pipe and silencer combo

Money no object? Sparks.

[ny300exrider]

[XANDADA]

ESR

I found this interesting:

i hear sparks are the best

[yellowex01]

Xandada. If you look they are comparing the center mount esr not the regular one. With the center mount you have to lose the airbox and put one of theirs on it. It is supposed to give more ponnies compared to their regular one.. Too bad they didnt compare pipe for pipe.. Thanks for the info.

Wow sparks is all over the place :huh . I would go with ESR, just becuase I hear good things from them.

[OutlawEX]

it dont matter,they are both extremely good,ones weakness is the others gain

[roostin_dale]

they are both GREAT but id go with the sparks

[ESR250R]

i would go with esr. if u want a pipe with all bottom end power just get the trx 6. ive never hear of too many people using sparks. i love how all these people with 400ex's talk about 250r pipes like they own a 250r and have tried all the pipes and they know which one is best (im not saying the i have). your best bet is to ask this question on rriders.com.

[yellowex01]

will do thanx

FMF isnt as bad as everyone complains them up to be...

[Dave400ex]

I would say a Sparks PowerValve, then a Duncan PowerValve.

The ESR has more HP than the Sparks TT in the dyno run I saw last week, but the Sparks had a smoother and more lasting power. Both pipes on the same motor.

[racerx573]

I've got a Sparks TT on the way :D I considered ESR and almost bought one, but I decided to go with Sparks. I will be running a lot of wide open MX.

Decisions Decisions.. Have to make up my mind by morning thats when I am ordering one or the other.

go with ESR, absolutely uncompromised customer service. if u dont like it, send it back no questions asked. and the trx-5 normal is comparable to the centermount, centermount puts about 1-2 more hp out.

ESR !!...I am a satisfied customer..they had it here within a week of ordering it
They were great to deal with & had lots of info & advice while building my building ESR 310PV motor ..

[yellowex01]

Thanks for all the help... Now I just have to sort through it all and order one.

[Dave400ex]

Best thing I think about ESR is, they make and offer about every 250r engine part you could ever want or need. Also he doesn't have a huge waiting list like Sparks, and you could have your motor back and running much faster.
