Curiously waiting for test result and release time frame.

I have a follow up dyno scheduled for tomorrow and Ron will follow up with the results of the dyno whenever he is ready. Should be very, very soon.

Nice. Do you know if they are a 2.5” or a 3” diameter?

I do not recall exactly, but they bolted right up to my Lethal Performance mid pipes, with no issue.

3"

~Update~

I had my ST dyno'd today and the dyno before the Whoosh Motorsports downpipes I maxed 458awhp to the wheels.

After the downpipes were installed, I maxed 482awhp today. Max gain of 24awhp!!!!

Cool! Show us the dyno sheets.

solid numbers, what mods

ZFG E50 Tune, Whipple Intercooler, Fenfab Cold Side Charge Pipe, Turbosmart BOV, MBRP Catback System, Whoosh Motorsports Downpipes, AFE Power CAI are the performance mods. The rest is cosmetic.

I didn't see these on the site.

They aren't available yet. I've been testing a set. Soon though, so keep your eyes open.

Are they designed to work with the stock mid pipes? Asking because of the reducers at the end of the pipes.
I liked the idea of having the option of removing the reducers like spd's (I believe they were spd) Would be a nice touch. Will whoosh also be fabbing mid pipes?

The current design works with stock mid pipes, as well as Lethal Performance mid pipes (which I have).

I am not sure if Whoosh intends to produce and sell their own branded mid pipes.

I like the idea of staying 3" all the way without reducers. Just a thought.

Why?

 

[Deric365]

Why?

Why not?
Why go the trouble of fabbing a 3" downpipe to bottle neck at the end of it?
Maybe it's plenty of flow with that reducer, or even 2.5". Just my .2 cents.

Downpipe looks great btw, welds look clean.

Wow - great to see real performance metrics from before/after downpipes. I want some to complement my 3" Thermal, but they look like too much of a PITA to worry about right now.

Those are some significant gains, but what was the temp & humidity like between those two runs? The initial pulls were done on July 25 and the DP pulls were done on September 14. I'd imagine it would be cooler during mid-Sept than during the dog days of summer.

Obviously, it would still gain, but with a back-to-back dyno post install, I think you might see less of a gain. The stock design of the downpipes are pretty terrible though, so it's not surprising that there's a good amount to be gained by doing this mod.

I live in South Carolina, where the weather is very humid and hot, well into late September. For both of these dyno days, temp was in the 90s, and very humid.

I hope this helps.
