Back pressure Q

[Domination]

well today i was just out bashing when i gad a hard landing on my lid and the exhuast got tore off and the coupler got ripped and all screwed up and i stuck i back on and drove it for a few minutes and noticed it has more excelleration and got to top speed faster. So my Q is does less back pressure mean more power ans speed or the other way around??

Your getting better power because by less pressure the engine is going to get less fuel and maybe more air. Which is leaning the mixture. It may have more power but how long do u want this engine to last? I would check the temps if u haven't already, it could easily cause overheating. I would get a new coupler before anymore runs if temps are higher. You will also have tuning issues in the long run if this problem is left alone.

ya m gunna go to the LHS in a lil while and i was thinking of maybe getting a new exhuast also to replace the stock. Would a .18 pipe be to run on the 2.5 cause since its only a .15??

Which .18 pipe is it? If it's the Sirio BB then yes that's a very good pipe for the 2.5. I don't have a 2.5 myself but I'v heard lots of good things about the Sirio BB.
