Question about exhaust

ClemsonVQdude · 01-31-2018, 03:37 PM

I have a 2013 Nissan 370z base and my next mod is going to be an exhaust. I have a question about the difference between 2 types of exhaust and before you waste both your time and my time by saying “use the search function” - I have, very thouroughly and have not found a post about exactly what I’m looking for.
So I know the stock exhaust is a 2.25 inch true dual,
I am debating between a 2.75 inch single midpipe exhaust that comes out to dual tips.. or a 2.5 inch true dual exhaust. Both are catback systems and both are from TopSpeed performance. I had a topspeed exhaust on my g35 that I had before my Z and it was amazing. Awesome sound and great quality.
So basically my questions about the two exhauts are what is going to be the difference in sound and power? From what I’ve seen while searching through posts I think I’m correct in saying that the single pipe exhausts are louder than true duals? So the 2.75 inch single mid will be a little louder than the 2.5 true dual? What is going to be the difference in power between the two? I’m staying N/A and will most likely be getting z1 or stillen intakes after the exhaust and I’m wanting a little noise so i’m leaning toward the 2.75” single mid pipe. Just wondering if theres a significant difference in backpressure and power between the two.
Thanks

None. Either upgrade will give you a 15 to 18 added hp over the OEM exhaust based on the typical dyno numbers. There are plenty of Top Speed Exhaust dyno threads on the forum. Thus, go with what you like.

BTW, just run a Google search of your question as it will pull up all the relevant forum threads. Works better than the forum search feature. https://www.google.com/search?ei=OVN....0.hVH5lCp7CDw
