    2013 Cadillac ATS - No true dual exhaust?

    It looks like the Cadillac ATS only has one exhaust manifold that feeds into two pipes, which feed into one muffler, which then feeds into two outlets.

    Do you care? I'm guessing this would mean more to Camaro owners - which would get the same thing...

    I'm not sure... I figured there'd be a discussion on this by now but I guess nobody is really concerned...

    Makes perfect sense on the four-cylinder engines to maintain a single exhaust, but let's hope they maintain it on the V6.

    None of today's I4, and most of the V6 don't need a dual exhaust. It's just extra cost and extra weight. Trimming down the exhaust system was likely one of the weight saving implementations.

    Yeah, that's a great possibility...

    The V6 has true dual.

    It however does have a common resonator instead of an H or X pipe. I4 Turbo is single to the back resonator, then dual after. The 2.5L has a single exhaust (no pipe out of the fascia).

    Re: 2013 Cadillac ATS - No true dual exhaust?

    It's alright on the four to not have "true dual" considering the T4 is the weight saving, power punching, balance base of this car's existence. The V6 changes the balance dynamic enough the extra weight of a couple of tubes shouldn't really matter.
    When you turn your car on, does it return the favour? '14 Cadillac ATS Performance 3.6L AWD in Phantom Grey Metallic and Morello Red Interior -ARRIVED!!

    4's can't really have dual exhaust. Since the exhaust is only on one side of the engine block. Only a V engine can have "true dual" unless you split the manifold on an inline (as I think one of the BMW twin turbo's did)

    Re: 2013 Cadillac ATS - No true dual exhaust?

    This is good info. I want to convert my 2013 ATS to dual exhaust as I do not like the way the single exhaust looks. So does this mean that all I
    need is that last muffler that has two outlets plus the lower valance that has two cutouts? I don't want to cut out a second hole in my single valance cause it won't look good. Any thoughts?

    GM Accessories has a Dual exit exhaust kit specifically for ATS's that didnt come with them that includes the rear valance

    4banger dont need true duals, if you want more power get rid of that factory DP, thats whats worst about the exhaust system.
