The race muffler + RB mid or duals + roadstersport mid

[senda]

Hey Brian

I install the RoadsterSport Stainless Midpipe + the RoadsterSport Stainless Steel Duals in my frund miata 2006 (2 liter). he saied it it making the car feel faster and lighter.

I want to bay a set for my self - for autocross use. We do not have sound limits in Israel.

Will the race muffler + RB mid or duals are going to give me more power then the duals + roadstersport mid ??

What will be the diff beside the noise and the smoke ?

Thanks

Niv

You will save a little more weight, but the power gain with the Race or RoadsterSport Duals is the same. Similarly, I have not dyno'd the Racing Beat midpipe but it is a SMALLER diameter so my guess is that even though it skips the cat and resonator there is not going to be a gain in flow or power with that unit as compared with the 2.5 inch RoadsterSport. So, bottom line is that I would expect similar results...but with a LOT MORE NOISE.
