Here's a short and crappy video of what the older style Greddy SP sounds like with straight through 3" DP and MP. A slight exhaust leak too lol.

Oh, and does anyone have an idea what the noise at 1:04 in the video is? I usually don't rev the engine up for the hell of it, so I haven't noticed that sound before. Doesn't sound healthy... *sigh*

 

I love it. Ill be running a high flow cat but it sounds great!

 

and thats just your turbos winding all the way down probably

edit: I second him from above.

 

Wow that sounds really good for no restriction.... must be the SP muffler

 

Sounds great! Bet the neighbors love it too!
