Hey fellas, hope all has been well with you and your loved ones.

So I narrowed it down to--

ISR Performance Single GT Exhaust for Nissan 370Z
OR
Manzo Axleback exhaust

The ISR Single exit Y pipe back exhaust is for the 370z so I would need to have the shop weld on an extension. I can buy this for $450, shop charges $100 for extension, $150 for installation.

The Manzo Axleback also would need an extension, but out of all the research I've done, these Manzo/Beluga/etc Axlebacks are all the same BUT they amplify the VQ note by a LOT which is exactly what I am looking for. I can buy this for $150, shop charges $100 for extension, $100 for installation.

Has anyone had any experience with the Single exit ISR exhaust? In terms of sound, I don't want it to change the exhaust note at all, I just want it to make the VQ exhaust sound way louder and maybe a little more "exotic". The only reason I am considering this is because it's a single exit exhaust which will probably make me not lose any backpressure compared to a dual exhaust.

Any and all input/advice would be much appreciated!!
