Yesterday, I deleted header cat,mechanic made it in 4.5 hours. Then I went to the electrician and he hooked me BMS DPfix. No errors, I hope will not appear.
The sound became a little louder. But here's how to write an additional 15-20 were added and I feel it. On the dyno I'm going later when i choose which tune to do. Total cost 390$ (cat delete 260$, 120$ BMS and 10$ to install it) |

Ahahhaha Ed: and i also read 'factory headers optimum design' some crap? LOL the headers are designed purely around cats asap to reduce emissions. They have VERY sharp bends and merge FAR too soon (gases too hot and buffeting rather than merging quickly) Yeah this is a mod that'll get you very noticable gains, but even comparing it to a real replacement headers... Totally another league. |

I still love this mod even if it took hell and a day to work out all the bugs but top end is a beast now. I still need a TRUE dyno tune cause im still running on AA's stage 2 tune. but i know there are more gains to be opened up with a true tune.
In time when afforable headers come out i will convert but for now this is the best my wallet has too offer http://www.youtube.com/watch?v=-c6S5FFYySo |

I don't think a race team is concerned with costs like the average Joe. They run through tires and brakes that cost more. Super sprint is only around $1300 or so now. Also they mentioned design as a reason stating that considerable gains weren't worth it over cutting stock pipes. Plus I have seen 15 whp dynos too.

The tires race teams run depending on what requirements are, are usually actually not too badly priced.. When the most exxy tires you can really get street are $400-$450 each |
