I have the HKS axleback exhaust with the megan racing midpipe and i want to add the megan racing S pipe. my question is will i see any gains at all? or is it just gunna make my car extreamly loud? I live in cali and super loud exhausts arn't good lol thanks for the help

 

you'll see a tiny gain, and a tiny increase in noise volume. stock s-pipe is more restrictive, but it doesn't have any sound supression devices in it, so it wouldn't be a huge difference in noise, but the flow of the exhaust would be faster, so it would be a tiny bit louder.

 

Did you search?

This information is out there. You will net a few whp but you're not going to feel it. The s-pipe is a very rescrictive part of the exhaust. You may get a lil bit louder exhaust note.

 

s-pipe wont make a big diifferece you wont noticed it..suppose to make the exhasut little deeper....but other then that not much

 

I had issues with the fitment of my Megan S-pipe. As the previous posters have noted, you'll havea gain you might be able to quantify but not subjectively. A little bit of noise, not much else.
