AAM S-Line mid pipe exhuast questions...

Sales@AAMComp

OP,

Below is the dyno chart before (bone stock Nismo) vs after (Bone stock with S-LINE midpipe)


As you can see the gains are definitely there, your rear muffler, albeit a Nismo, still is a restriciton. Yes it will taper down if you run the stock muffler. When we test drove the Nismo with the midpipe only, I honestly think its VERY similar to stock, if anything you gain a bit of bass in the exhaust note, it's extremely tame. As far as I'm aware, we've sold over 10+ sets of the midpipe since the release of it. From what I know, one person is running it with the Nismo muffler, but I'm not sure if she is on the forum or not

Here is a great picture, this is our midpipe mated to a Non-Nismo muffler

Thanks for the pics! I didn't want to have two different diameters bolted together and wasn't sure how that would work. I don't have a nismo so I'm assuming I'll see a little bigger gain with your mid pipe due to the fact that I would be getting rid of the even more restrictive stock y-pipe for an h-pipe design. Are there any fitment issues with your mid pipe and a touring 370? Anyone know what the differences are between the non nismo and stock nismo muffler? I'm curious if it's worth it to swap out my non nismo muffle for a stock nismo muffler. I've read the nismo muffler is heavier but that's all I really know. Not sure if it's less restrictive and how different the sound is.
