Yes it is important to calculate your exhaust system before you install it for the best benefits. |
right on dude .. right on ..
I agree exactly with you . thats what i was playing around with with my experiments ...
cat = tiny holes = some amount of baffle effect = incerease of back pressure = low end torque increase ....
so when I removed the cat and put large dia pipes .. I got loss in low end (I have no probs with that) and gained top end torque (love that) ... in short low back pressure = higer top end ..
thumbs up to u dude .. I also was going along those lines ..
