SHO exhaust thoughts?

[Night Hawk]

I'm looking to put a different exhaust on my 2010 SHO. I have looked at numerous exhaust systems and I looking for advice on what is good performance wise and sound. I want the Corsa exhaust but do not want to drop that much coin right now. So any cheaper exhaust that still sounds good out there?

I did exactly that when I first bought it due to lack of funds.  An x-pipe (magna flow) or Nesho in place of the resonator and simply a pair of quality flow through mufflers magna flow, dynomax, borla welded in, work fine.

I can understand why you would want to remove the resonator but why would you use an x  pipe instead of 2 straight pieces of pipe ?
It looks to me that this is taking  the exhaust from each downpipe and merging it  in the cross section  causing at least some turbulence and restriction before splitting again into the rear dual exhaust .
The  Corsa  does not do this and has no x pipe.... its straight through .

I've been wondering that as well. I get x pipe vs h pipe but no clue how it compares to straight through...

Its my understanding, believe it or not, that an "x" configuration actually flows more efficiently than individual pipes.  I guess testing has shown this.  NASCAR cars use the x as well as the newest versions of the Shelby GT-500. The sound sure does sound nice as well IMHO.  I will be bolting up a Corsa system soon so I'll let you know first hand.

Perhaps the x-pipe is also to equalize backpressure on all cylinders, especially given the difference in length of the down pies from ant and post 3 cylinders... So that all perform the same

It's kinda the bass akwards version of the the straight 4 banger with dual exhausts .......

conceptual differences on back pressures = hokie ,  I trust Corsa and Livernois ...

NIGHTHAWK  , I think we are dealing with  a whole new bread of engine tech here , normally aspirated old school versus GDI twin turbo . I highlly doubt back pressure is a factor in turbocharged engines unless you are dealing with large amounts of restriction.

   I think its more of the flow being more efficient than back pressure.  In most of our cases I doubt it would hurt with either set up.

If that were truly he case why would exhaust mods even exist with our platform?

4drs cutout says there's at least 2/10ths worth.

POORLY Phrased I ment .... equalized back pressure.





HEY DJE ..don't go dyin on Me ....

  LIVERNOIS is a good company they just should have  never announced a product such as XV1 prematurely until deveopment  was further down the road .
In our world its akin to Apple saying the iPhone  6 is being released next month and 9 months later it still is not on the shelves .... IMHO

Dynomax 53752 and 537523 are the individual part numbers, get your own clamps.  $196 on AAP pretax shipped to home.  Still don't see it on AutoAnything, am I missing something?
