Thank you to all for your replies, you are appreciated!


Anyone have a C7 stock X-pipe for a Base Model C7 somewhere near Houston that is collecting dust in your garage you might like to get rid of?

Thanks!

cuisinartvette,

When you did this was it a deeper sound without an X-pipe or H-pipe?

Warning: Actual explanation follows.

Separate pipes will be a more old-school sound. The big difference is the asymmetry of the firing order - think of which side this happens on:

1-8-7-2-6-5-4-3

Left, right, left, right, right, left, right, left,

So it does 3-1 (two lefts into same header) on one side and 2-6 on the other (two rights into same header), which sounds DISTINCTIVE and you lose that sound, or some of it anyway, by allowing it to cross over and cancel out with sound from the opposing bank. You'll also lose some power due to increased backpressure by eliminating crossovers.

It will sound "old" because your brain is used to older muscle cars without H pipes having that distinctive sound signature, just like a Harley sounds like it's always about to stall in a very distinctive manner. Even though the firing order switched on the LS, and people will tell you that makes a sound difference, I think it just swaps it side to side, should sound about the same.

However, a fair number of C5 owners switched over to X pipes and found sound levels increased as well as power.

Bill
I agree

This

and it will occasionally stall at idle due to incorrect back pressure and scavenging

I might have one soon off of my 2017 grand sport. Will let you know if I go that route. I track my car about four times a year and I like still having a warranty for that. So I am not sure I will do the Borla X pipe or not.
