exhaust question

[Cobra4pt6]

will running straight pipes (stock h-pipe and no mufflers), will this setup decrease top end pull or increase top end pull.....

 

[Poisonous Mods]

Id say u will gain HP up Top but U will feel a loss down low in TQ & HP should suffer a bit.

What are u thinking of?

I agree with that. You'll feel a loss down low but gain up high.
These modulars like a little back pressure.
