Exhauat Smushed down
 

Have any look under the Gen 6 and seen the way Gm Smashed the backend off the exhaust to clear the tubes running too the rearend. Will the aftermaket exhaust have to be the same way cause i just was gone get axle back

Aftermarket exhuast system do not have this flat area on their pipes.

Yep!! Here is my exhaust off today.. Anyone know why GM did that??

While it has been covered about a million times on this very forum... The crushed pipes are done so there is no drones, according to the engineers. And aftermarket exhausts do not have crushed pipes. Also, if you decide to cut them and replace them with 2.75' pipes, it will NOT result in ANY extra sound NOR power.

Word

The Smush Makes no difference powerwise. All Aftermarket systems will likely eliminate this though..

It has been tested that the crimped pipes make 0 difference in HP.

Yup, never been discussed before. Search is your friend.

If they did it to eliminate dorne how does replacing them not add more sound?
Im confused as to why opening up the exhaust doesn't add power and noise, do you know why?
I also assume given your definitive statement this has been tested and verified?

Apparently you did not read this....Reading makes you smarter

I think there is some confusion here. You two may be talking about two slightly different things. This weekend I did a custom exhaust on my 1SS. I didn't have NPP, not sure if that makes a difference or not. Anyway I had them cut the exhaust and muffler out right before the crimp. Then I did two separate 3" pipes all the way back with 4" tips. It's way louder. Not sure if more powerful. So my question is did the Mishimoto test remove the crimps and replace with non crimped pipes before the muffler? If so, I wouldn't imagine any change in sound or HP because it's still before the muffler. I'm not an engineer.. This is just a guess.

Thank you for the article
Condescending is not necessary and usually counterproductive

Said the pot to the kettle....:rolleyes:
