Short tails torque loss fix??
I am thinking about purchasing short tails and have two questions
is there a way besides tuning to fix the torque loss and does anyone how much torque is lost or have a dyno of the difference. |

i can just feel and hear a difference. also so far the 1/4 miles times are almost identical with both set-ups. i do need to re-tune soon and i'm sure the TQ loss would be gone. just been lazy and it's not bad enough to pay for a re-tune to smooth out 1-3WTQ loss. |

but with my set-up oringinally i only had mufflers acting as back pressure. now without mufflers i can feel it. you'd be surprised how much pressure the mufflers on the exhaust hold back. |
Yeah someone awhile ago opened up a stock nismo? muffler and it was jam packed full of steel wool. The axel back and cat provide the most restriction to the system overall in that order.
|
So technically using AAM short tails there will be a marginal torque lost on launch but nothing noticeable? Such as when driving you won't notice a performance lost?

I had the aam short tails for a while and there was an immediate feeling of loss torque when pulling off of red lights and stop signs. I had test pipes and it was loud as **** but slow as hell launching. I have been wondering if buying the entire mid section and tails would help with the amt of loss but I don't really see how it would.

The vast majority of the back pressure in stock form is in the muffler, no matter how you slice it. Same way with every other exhaust system. Correcting for it takes a tune in some form or fashion.

It may not be as bad if yiu have short tails only and leave stock cats on the car. I had test pipes. |

honestly I think it's not as bad as most say it is. mine I feel is that the sound comes on so loud so quick it makes you think you should be going faster based on volume. |
