A.R. Headers Pics And Dyno Results!!!

[JTHennessey]

Nick... We will have the Official Corsa in our hands tomorrow and will advise you as soon as we have images...

Talk to you soon

Nick, were you able to clarify the matter further? Are you going to be incorporating all 4 cats, at least as an option, for those of us in the CARB state (and other states that have adopted/will be adopting CARB standards)?

Nick,

will you offer a complete 3" system?

thanks

Glad you asked this question, as I was thinking about this as well. For as much HP as the LSA generates, shouldn't we WANT a 3" system? I guess I'd raise an eyebrow, if not be outright disappointed, if the entire system wasn't 3". I read somewhere that once you exceed 450 rwhp (was it? Something like that), you wanted to go with a 3" system.

SSideways, We can build the system in 3" if we had to. We believe you'll produce better all around performance with the system the way we built it. The critical areas (most restricted) of the system are now breathing freely and downsizing the system where we did will increases exhaust temps further back in the system to maintain velocity in the system. If you plan on really turning up the boost to produce 750 or more RWHP then we can increase the intermediate pipe size.

Nick,
the reason I'm asking is because what documented on hennessey website for the corsa exhaust is:

• Straight-through, 3” nonrestrictive design specifically tuned for the Cadillac CTS-V.

which turns out to a frankenstein system 3" to 2.5" back to 3" which equals more modification. So It would be wise to have a 3" and 2.5" mid pipes to be feasible with any type of exhaust system.

thanks Darren

So...I take the lack of a response as a NO?

GMX322V, At this time we have no plans to offer a system that re-uses anything but the factory mufflers. Our system is built to work as a unit. If you take a close look at what the original system looks like you'll understand that using any of it is counter productive. BTW, I'm told the Corsa is 2-1/2" to the muffler but I need to confirm this.
