munckee,

I have not done this on my S2000, but I did do it on my previous ricer car. I had a muffler shop cut off the stock muffler and then weld on an aftermarket one. They just slapped on an universal clamp and hanger to hold it in place.

It changed the sound pretty noticeably. It was louder and deeper. The exhaust was super quiet before, but after adding the muffler, it was kind of like a nice rumble at low RPMs, which tapered off at higher RPMs. However, if you listen closely, you can tell that it's not a full exhaust system...the sound comes from the back of the car, and doesn't surround you like a full exhaust system does. The S2000 is a much smaller car, so I don't know if that would apply here. Btw, don't laugh, but this was on a '95 Mitsubishi Galant. Ok, I change my mind, laugh all you want. =)

 

My brother put 2 Hayame cannister style mufflers on his stock exhaust. It's deeper now but not too loud, no droning , no bees in a basket sound. $250 installed. He dynoed before and after . He lost one H.P. and gained one T.Q. which means only that he didn't loose any H.P. Good looks and great sound, no loss in H.P. , cheap!

 

Thanks for the info. Do I need to get cannisters with a certain size inlet pipe?

I was thinking about going with something like these:

I had an Apexi WS at one point and I loved it, so I figured these might offer something similar. They're also about the only ones I've seen, so if anyone has any other recommendations, I'm certainly open to them.

 

Be cognizant of the exit angle between the new mufflers and OEM pipes. IF they cut too much from the OEM piping, your new mufflers will tuck in too closely under your fascia and you'll risk melting it. Also, if the angles are wrong, you'll stand behind the car and the mufflers will be exiting at different angles. If you're going to go this route, go to the best shop in town, unless you personally know a reputable exhaust specialist at your local M and M's. (Meinke and Midas). I took mine to the owner of the local Meinke because he was an exhaust specialist with 25 years behind him. Normally he rarely does the work anymore (runs the place) but we've been friends for awhile and he looked at the job as a blessing since it involved creativity, not just slapping yet another muffler on a '93 Sentra XE, ya know?
Still, for only $150 or so more, you can get a full on Spugen system. Something to consider.
