Regarding SPD Downpipes- they are already the most expensive option at $1,399. If you want GESI cats instead of the “highest grade EPA approved catalytic converters” then the price goes up to $2,499.
Question 1- are the standard SPD downpipes worth more than double the cost of the whoosh...
Thanks Tmac. I’d spring for the turbo upgrades but no one seems enthralled with the performance gains by upgrading the stock turbos and I have not seen any aftermarket companies with a packaged single turbo option for sale.
Thanks, Tmac. I’m surprised though at your answer. From everything I have read that you and Unroken, there were no gains to be had from either the AFE intake or an exhaust. Why do you recommend the AFE intake rather than a better set of downpipes? Will changing downpipes only net any MPG gains...
Not a bad idea but no way I’m replacing the hood after what I have spent on PPF to cover the entire front of the car. If someone made ones that can be installed into the existing hood I’d consider them after I saw some pics of other people that had installed them and gave good reviews.
Thanks. That is what I was thinking. I always try to maximize cooling in my vehicles. My Miata has an oil cooler, transmission cooler and a diff cooler. Plus I added hood vents. Keeps it nice and cool day to day and doesn’t heat up as much as it otherwise would on the track (which I rarely go...
Best gas we have in North Phoenix that I have seen so far is 91. And so far haven’t come across any ethanol options. So sounds like for me that doesn’t make sense. So I guess aside from cosmetic improvements (looks or sound), really the only way to get more power from these trucks in a cost...
Is there ever a reason to add a BOV on a 2023 model without one? For example, if you upgrade the turbos, then is it a mod that would be helpful? If it doesn’t either protect the engine, increase MPGs or add power, then I don’t need it.
Ok looking for some more guidance on Turbos. For someone just looking to maximize bolt on performance who isn’t capable of making one turbo to replace the two, what kind of results can you expect from, say, sending your turbos to Whoosh Motorsports for a Pure Turbo rebuild?
And a second...
Dang it. So besides the $2500 SPD option, which downpipes have cats without them?
I confirmed with CVFab that they do have them. Below is their response:
“[T]here are two defoulers in the box for the two lower o2 sensor holes on the cats themselves. It’s standard for any aftermarket...
I don’t know what those are but it doesn’t say anything about them here: https://www.cvfab.com/products/st-dp. Just says 400 CELL. How do you tell if the cats aren’t good?
I guess (at least for me) it doesn’t matter anymore since I just pulled the plug. I couldn’t resist the current discounted price on the CV Fab downpipes at $540 shipped to my front door.
That said, I’m still interested understanding whether there are any differences.
Has anyone done a comparison between the various downpipes on the market?
I am looking at the CVFab and Whoosh versions. The SPD downpipes look nice but not nearly nice enough at nearly double the price of the others. I’m sure there are others to consider as well.
So what are everyones’s...
I would but my wife drives it more than I do and she loves that it rides high. She wouldn’t let me lower it so I need to find an alternative to the lowering springs.
Thanks. I definitely do not want to lower the vehicle. Already have Steeda Front and Rear bars and toe links. What shocks and what other components would you recommend?
If I was installing myself I absolutely would, but I have a number of items including an intercooler so unfortunately I’ll have the shop install along with the other parts. The instructions are available online. If you cannot find them I am happy to post them here for you if that would be helpful.
