Sibling Rivalry: BMW 550i exhaust showdown
Exhaust Showdown! We get asked this question all the time: which exhaust system is the best one? Which one is right for me? And the answer really is the truth is it all depends on you and your goals! We are going to shine some light on what rolled into our Norcross location recently; two sibling bmw 550i, two owners with two different needs.
Up first is a long time client with their 2014 BMW 550i in Rhondite Silver. This F10 boasts BMW’s N63tu 4.0 V8.
Our client previously had our signature SMS tune to accompany their 3.5in VRSF downpipes, seems it only took a little taste of power to bring them back asking for more! For the revamp the team installed a one of a kind custom turbo back exhaust, new electric cut-outs and a all-new intake alongside a relogged SMS tune, pictured below
Before: 379wtq/312whp/Dynojet HP 358
After: 508wtq/457whp/Dynojet HP 526
+ 130whp +145wtq. Outstanding.
Fun Fact about the N63tu; it’s the world’s first production car engine to use a “hot-vee” layout, with the turbochargers located inside the “V” of the engine The N63 is also BMW’s first V8 engine to use direct injection.
What about something that’s little bit more practical, subtle & a true sleeper? This gorgeous 2011 Deep Sea Blue 550i came in for routine service to clean out filters and ended up with a lot more fun going under the bonnet. It is a no brainer to say that they are absolutely pleased with the overall mods and results of the SMS Tune. Our customer chose the same direct bolt on 3.5″ downpipes that the Rhondite Silver 550i boasted. The improved 3.5″ downpipes offer less restrictive air flow reducing back pressure significantly which results in faster spool, an increase in power & a more aggressive exhaust note, making this a pleasure of a daily driver and an excellent choice for an upgrade.
Pictured below is the aftermath.
Before: 379wtq/312whp/Dynojet HP 358
After: 499wtq/373whp/Dynojet HP 429
+120wtq & 61whp. All smiles around.
