SAC Work their Exhaust Magic on Chevy’s Lumina SS

Chevrolet’s potent Lumina SS is legendary in performance car circles and this latest generation muscle car is almost all that a driver could want. But what if you are the type of enthusiast that wants something more?

Enter Steves Auto Clinic with their 30 years of experience in the performance enhancement business and their class leading and professional approach to extracting reliable horsepower.

Just as vehicle performance technology has moved on, so has exhaust technology.

Chevrolet Lumina SS Performance Exhaust System / Engine Upgrades.


Paying as little as possible for an exhaust system translates into you more than likely getting a noisy system that is generically bent, and ultimately crimped closed, on a pipe bender and welded to universal mild steel silencers.

But this is certainly not the case with the completely handmade, stainless steel, mandrel bent, 76mm system that is available for the 6.0 litre Generation IV V8 powerplant on Lumina. This system is equal in terms of quality, look, fitment and power gain to any system, costing thousands of Euros or Dollars, on the shelf overseas today.

In standard form the Lumina SS produces 270 kW at 5 700 rpm and a peak torque of 530 Nm at 4 400 rpm,

strong enough to get this full sized sedan to 100 km/h in a fraction over 6 seconds, 200 km/h in 23 seconds, and stop at a limited top speed of 237 km/h.

On goes the SAC exhaust and now not only does your Lumina sound the business, it also goes quite a bit better thanks to the extra 20 horsepower that is now on tap under your right foot. 100 km/h comes up in under 6 seconds in a tyre smoking blur, and 200 km/h is dispatched in not much over 21 seconds.

Thanks to a little R1 000 mod that can be done at the same time as the R12 000 bespoke exhaust system is fitted, the top speed limiter is removed and the Lumina now also romps to a top speed that is on the fast side of 260 km/h.

Of course, as is always the case at SAC, you have a few other options available to you. You can leave the standard limiter in place; you can enquire about a cheaper mild steel option or even a more generic non handmade performance exhaust for your SS.

Whatever your needs or your budget, SAC has an option for you to consider, so to find out more about this upgrade and the other popular options for the true enthusiast like gas flowing the heads, fitting bigger valves and fitting performance camshafts to really take your Lumina to the next level, visit www.steves.co.za .

Bolt on exhausts

Gone are the days that you take your half a million-rand Bakkie to a corner exhaust shop for a cheap free flow exhaust. It’s fair to say that the bolt-on free flow exhausts of today at SAC have been revolutionized and are becoming more and more popular amongst the enthusiasts. It is no longer just a poorly welded and routed exhaust that rattles and knocks over every bump, it is a properly engineered, big bore, mandrill bent stainless steel-low restriction exhaust system.  It is manufactured in such a way to be a bolt-on fitment in a workshop with very little effort to ensure perfection. Seeing the exhaust system in its raw form, packed and laying on a shelf – it is clear to see that this is an export quality product that will be installed on your vehicle, and it will compliment without any doubt – the performance enhancement plug and play kit and or upgraded intercooler system in many ways – most of all the sound and power will be much improved.  The bolt-on exhaust system is routed along the exact same rout under your vehicle and hangs with similar brackets on the standard rubbers.  The heat protection that has been provided by the manufacturer under your vehicle to protect the undercarriage is still effective and useful with the fitment of these bolt-on exhaust systems.
