    Alright ladies and gents- I’ve been working SPD Performance on a new exhaust for our platform. Just installed mine yesterday and I’m excited how it’s come together.

    Some features, full 304 stainless, mandrel bent, high flow cats with the option of secondary cat delete, x pipe option on the race version like mine, full equal length, additional bung welded in for a wide band for our blown setups, high clearance, only dumped tailpipe option, plus more.

    I lost 1.5psi or so in boost and the truck is hauling the mail (aka efficiency way up) . I’ve got a an idle video then a full pull video of anyone wants to see that. Revving at idle is super snappy like a bike or coyote engine it’s wild.

    This sounds fantastic. A new exhaust wasn’t on the list but might have to be now.

    Very nice! Sounds sick

    So this system bolts up to the stock manifolds?
    Any info on pricing?

    What’s the “S” section before the X-pipe? I don’t understand why that’s part of the system, is it for drone?

    Yes, that’s to create the equal length. Can confirm this does breathe much better.


    Yes bolts up to the stock manifold. I’ll have firm pricing next week but $1,200 or less for the full system.

    Yes this will include high flow primary’s and secondary’s on the mild version. Race will have no secondary’s and an X. Also added a pic of the recessed gasket flange.

    All cats are high flow for sure. I’ll see if they’ll add an X option for the street setup. But they may not since he mentioned he likes it as is and it’s pretty dialed. But maybe custom option.

    He can test it on my truck. I'll send him sound clips... :D haha.

    Seriously, though, that setup looks NICE. Sounds mean but not obnoxious.

    Adding this to my watch list. Interesting design. Price looks good.

    I think most don't do equal length due to weight. Curious to see what gains it offers if it boosts the crossover scavenging post cats at all.

    1.5 PSI from exhaust + cats and making same or more power would be ~+6% efficiency in my build, something overlooked on blown builds.

    I may have missed it, what pipe diameter is it?

    Looks like 2.5” from the cat back?

    I agree - price looks good, build quality looks nice, and better efficiency is great.

    The 304 vs the 409 most are selling is a plus too.
