PM sent! Thanks!

Can you post a link to this clip? Atak with resonator.

What cell count are the “green” kooks cats? I think the SPD’s are 400. Which are better for performance? Is there a significant difference between the two? I assume the green cats will pass emissions in the 48 States? Might the SPD pipes not pass emissions? I live in Dallas Texas, so...

Nice! Any chance you can make a video of your exhaust? Inquiring minds would love to hear it!

This was an accidental post. Not sure how to delete posts.

Howdy, any of your customers have the ATAK or S-type with resonator as well as SPD adapters and downpipes? I have heard a couple members comment positively on the sound of that set up. No sound clips of that setup yet that I know of. I wonder how the S-type with resonator and...

Whipple Charged, Solid, quick, and detailed response as usual. Two thumbs way up. Might just have to skip the wait for the next (if ever) group buy. Just too excited to rock this setup.

Supposedly the SPD catted down pipes don’t throw codes either. But they have been of little mention on this forum after their release. Texas Motorworks told me about these when I visited a few months ago. I do know that the Kooks catted down pipes are over $1000 I believe. The last time I...

Good question. Though I do hope Whipple (working with ford engineers) would not sell a purely superfluous, sound-generating only intake. I have read many times that the stock intakes are well made and support some tuning. I think the larger airflow only comes in when substantially tuning the...

Howdy, Since Whipple Charged answered my questions regarding his tune and some aftermarket goodies (and gave me some possible HP/TQ gains with each additional mod) I decided to have some fun. All calculations are based on Toadster’s recent dyno pulls. I rounded to the hundredths place...

You sir are awesome!! You have earned yourself a customer!! So it does appear that the Whipple Stang 1 kit on 93 shortens the gap with the MPT 93PRX. Please do keep us posted on that second group buy! ---------- Post added at 02:27 PM ---------- Previous post was at 02:21 PM ----------...

Whipple Charged, So I’m 98.4% sold on your stage 1 kit. According to the math earlier in this thread we are at 530BHP / 581TQ at the crank with this tune and SPD adapters...everything else stock. A few questions please: 1) What would you estimate that the power increase would be running 93...

Howdy. Can you please provide a link or a part number to the Borla H pipe you used to replace the x pipe? I can’t seem to find it on the Borla website. Also, which downpipe are you running? Catted or non-catted? Thanks!

Merry Christmas Merica!!

SPD Downpipes now available Just saw these today. Not sure if this has been posted yet. Mandrel bent aluminum. 6 week wait. Non-Catted: $550 http://www.spdperformance.com/index.php?main_page=product_info&cPath=566_567&products_id=141&zenid=uk839nmgpoiq89cg3hkg6q4cn5 Catted: $750...

And let me just add this. Ford sells a whole lot more normal 3.5 eco-boost motors than it does Raptors. This is a well-known fact. If Roush can tune the normal 3.5 for an almost 33% jump in horsepower and torque then I’m sure the same thing can be done for the raptor. It just doesn’t make...

So the normal 2017 3.5 eco-boost gets a 100 to 110 rwhp and a 130 rwtq increase. We only get 34 hp and 52 foot pounds of torque. I know that the normal 3.5 eco-boost in the 2017 also has direct and port injection. The increases from this tune for the 2015 to 16 is much much less. But we also...
