Okay, I know this has been debated before Moses parted the seas, however my friend bought a Spugen Single but sold his car due to personal reasons so I acquired his exhaust and took some time to play with it.

As some of you know, I have the Spugen Dual Ti V2's and I've been using them for some time. The install and appearance is nice and it's a lot of exhaust for the price. The single isn't the Ti version, but it uses a polished can with a Ti tip.

Install: Both are easy, but naturally the duals take an extra 20 min to install. The exhausts are spec'd out well and don't move around too much. Duc at Spugen thought out the hanger locations very nicely.

Sound: No comparison, the singles "appear" to sound twice as loud and there's a lot of droning in the 3000-5000 rpm range. If you enjoy listening to your OEM radio/CD player, this isn't for you. I personally got a headache after driving around for a week with this exhaust but the sound at wide open throttle is friggin' awesome! (sounds like a deeper-tone street bike)

Performance: Hypersports got to dyno my car after having my single exhaust installed for 2 weeks before I went back to my duals. The singles put out 8hp peak and noticeably 3 more hp between 4k-7k on avg. The fact that Spugen decided to angle out the cans to the side allows for minimum bends and a much smoother airflow.

I need my car to sound less noisy until I get a stereo upgrade, so I'm sticking to the duals for the time being.

 

dude, did you just get back or something??? no posts from you for a while, then BOOM...some post-whoring action

 

no kidding! where da heck u been? we were all wondering y u were MIA.

 

I wish I had to working exhaust!!

 

Stick with the duals. With the way the cops are circling the wagons, I would draw as little attention to yourself as possible. I'm thinking I should get a quieter dual (like the Amuse or Mugen) so I will stop getting harassed, but I would hate to get rid of the J's as I love my exhaust. I'll wait and see if I still get pulled over even with a stock height and front plate installed. Maybe they'll ask me for a recon for my paint scheme

 

Okay, got a chance to talk to a judge during her off-hours at a local Starbucks and I asked about the whole noise issue.

She says that the problem has very little to do with just plain noise, and that it also has to do with safety (like having an exhaust so big that it hangs literally mm's from the ground) and problems like kids just constantly revving in urban areas, not even moving.

I asked her about the Harley Davidson issue where there's no way even Steve can out db those choppers. She said they don't tend to pull those guys over because it's hard to tell whether or not that was stock or modified in the beginning and the other has to do with the nearly zero percentage of kids on the choppers to start with.

I'd like to go with a single as I would love the extra few hp, but I also enjoy listening to my stereo also. Decisions, decisions...
