I noticed my pipes do not have the same spacing. Big gap in center between pipe two and three? Anyone else seen this on there's?

Taking my car into dealer for body corrections tomorrow and to show them gaping on exhaust.

Happy to post this picture for you Corvettedriver1492. Would be fine it you had a C6 which had a "larger middle gap," but, as we all know, the C7's gap is uniform between the four pipes.

NOTE:Info I posted immediately above was/is incorrect for the stock exhaust, as per mjw930's correction below!

No, the gap is not uniform unless you have the performance exhaust. The stock exhaust is a 2 into 4 affair and the gap between the 2 banks of pipes (the middle) is twice as wide as the gap between the 2 paired tips. There's nothing the dealer can do, it's the way it's designed or at least it looks that way because every one I've seen with a stock exhaust is like this and I've seen about 10, 6 had stock pipes.

Correct Elegant my C6 was that way. Thanks guys.

Thanks mjw930 for teaching me that difference about the stock exhaust. I am now better educated. Thanks!

Good to know, thanks

Can someone with NPP discuss the sound difference with and without? Perhaps a video. If you do not need 5 or 10% more horsepower, is it worth the cost?

It's much more then added HP IMHO. Driving the car makes you feel like your driving a sleeper when at light throttle but when you get in the gas the bad boy comes out and your car sounds like it has straight pipes!!!!!!!!!!! Popping and all LOL!

 

[Corvettedriver1492]

It's a 5 hp gain.

More of an observation since it's not published anywhere and maybe they will make an inline change to correct it, who knows?

Here's some examples.

Stock Exhaust:

Dealer has order new exhaust for mine as none of the spacing was uniform.
