Is there much difference between the two? I looking to go with eaither one in 3 inch..... Any help would be great.... Looked for sound clips but can't find any for the harakiri

 

These aren't the TDX version you are looking for but its something to work with.

anyone have any info.......

 

I'd go with the Harakiri. . .

I've never had so many compliments on an exhaust before. . .people would always ask me what kind it is and how sweet it sounded. . .

I wish I had some fly-by vids of it, the dyno vids don't do it any justice. . .

I sold the car last year. . .buddy said he'd buy it only if the exhaust stayed haha. . .

 

I would run harakiri or Gamma

 

Why do you guys say run that? can you let me know

 

i might be getting tdx v2. sounds pretty agressive to me, but not over the top

or i might keep what i have and eventually sell the Z. lol yes 2 completely different ends of the spectrum

 

anyone else have any info??????????????????

 

how much more info do you need? exhausts are a personal preference for sound and looks. you already limited your search to MD TDX's line so the difference in power gains aren't very drastic.

 

I highly recommend the 3" TDX for FI. The way this exhaust is designed allows for easy modifications (such as cat incorporation into the primaries to minimize power loss from immediate post-turbo placement). The v2 shockwave axle back will eliminate drone. I have sound clips up somewhere... I actually tested using a RTA in the car and swapped several mufflers back and forth.

 

I may have a deal goin on to get a tdx so we'll see. If it falls threw I'll just have to settle for the greddy. I can't wait for a min. of 7 weeks till they come in.
