well the reducer i put in the exhaust tip seemed to create back pressure. boost lag is improved. but it's still not as restricted sounding/feeling as the injen can. i am extremely happy how the car runs! it rocks! al even tho you are a dick, your tune is awesome! 
THANKS!

after switching to the magnaflow can (3" straight thru vs the Injen can 3" reduced down to 2 1/8") the car does flow better. it also runs better up top (rpms). but imo the car suffered noticibly down low. i have a ton more turbo lag whereas b4 i hardly noticed it. i'm sure the overall hps with a free flowing muffler is higher but i'm willing to bet the torque curve has dropped. i definitely noticed between shifts the car lagged a lot more than with the injen can. for drag applications the hp gains are prob worth it but for tracks with twistys where you shift a helluva a lot more i think the low end torque with less lag is important.
so what i have done is made a reducer pipe (3"-2 3/8") to try and create some back pressure. we'll see if that helps my spool. regardless tho, i'm happy cause the injen pipe was too restrictive.

You may have some serious problems though if you keep company with man hands!!!
Have you thought about throwing a quick release v-band clamp on your mufflers?? That way you could switch between the two depending on where you were racing in just a matter of minutes. Just a thought........
And one other question: does the fuel pump get loud and go back to being quiet sometimes? Earlier today it was pretty noisy, and now it's back to being pretty quiet... at least, I think it was the fuel pump, and hope it was that
