Use the Dynamaite 007 - it will work great on your tight track. See if you can track down a 13 tooth clutch bell too. Then you will be wheel standing out of the corners with the 5 Port

I'd use the 007 it's their hightorque pipe good for more bottom end but you'll need to be a little gentle with the throttle or that 5port will bite you in the butt down low. the fuel consumption will be ok but not as good as a GO 2047 or the best GO 0801

grizz and retro are right in my opinion..

ok this is my opinion about the pipe, it shouldn't matter how the track is, if an engine will perform better with one pipe than with the other regardless if it gives it more bottom or top end, then use that pipe, the 5 port has a lot of torque, and don't need anymore so I don't think the DYN 007 will help, you probably will be spinning tires and have no traction, just googled the STS 0403 pipe and according to people it is a Mid to Top pipe which will probably suit the 5 port better, but then again, I suggest you try both pipes and see which one you like better (performance, fuel mileage, etc)

I also have the 5 port, I have tried the JP-4, JP-3, Hyper 2059 and an OPS Pipe, I'm relly impressed with the performance of the OPS pipe, it kind of smoothed out the engine and it gave great top end, my 5 port has never been so smooth with this pipe, I really recommend it.

I couldn't find the OPS anywhere else but on ebay, it's like this one: http://cgi.ebay.com/OPS-ALUMINUM-PIP...QQcmdZViewItem

I CHECKED THE MAIL AGAIN TODAY. NO STICKERS. I SPENT $15.00 ON TWO WING STICKERS OVER TWO WEEKS AGO. I DIDN'T HAVE THEM FOR MY RACE SATURDAY. NO REPLY TO MY EMAILS. COME ON, HOW HARD IS IT TO PUT 2 STICKERS IN A BUISNESS SIZED ENVALOPE, PLACE A FIRST CLASS STAMP AND MAIL IT OUT. I THINK I JUST TAKEN FOR $15.00. FIRST CLASS PRODUCT, WORST CLASS SUPPORT AND SERVICE. MY NEXT ENGINE WILL BE O.S. AT LEAST THEY SEND A RESPONSE TO CUSTOMER QUESTIONS AND REQUESTS.

What stickers are you referring to?

THE RACE FACTOR WING STICKERS I BOUGHT OFF THE WEBSITE FOR GO TECH, THAT ROCKET TOLD ME TO USE.

NOT ME PERSONALY, BUT THE WEB SITE HE POSTED ON THE BEGINNING OF THIS THREAD

were they just the ones that come in the box?
If so I may be able to help you out...

I have some that I created, they look different than the ones that come in the box but are approved by Russell for the contingency program or just general use.

NO THANK YOU....I PAID THE COMPANY MONEY. THE COMPANY NEEDS TO STEP UP.....THEY SUCK THATS IT...I EMAILED THEM WITH MY PERSONAL CONTACT INFO...IF THEY DON'T CONTACT ME, THEY DON'T CARE.....THEY GOT MY MONEY FOR THE ENGINE AND TWO WORTHLESS STICKERS....THEY ARE NOT GETTING ANYMORE OF MY MONEY OR SUPPORT......IT'S NOT YOUR FAULT...I REALLY DO APPRECIATE YOU RESPONDING

There's been some change over at Racefactor, I'm sure it was just lost or maybe the website is not working on their end. (the website hasn't been updated for a long time) Russell is a great guy, he wouldn't let $15.00 worth of stickers ruin his reputation. I have quite a few stickers, tell me what color and your address and I'll send you some.

Pm me
