What is the difference between SP2 and EVO exhausts?

What happened to Trust Exhausts? I can only find Greddy... I know they are the same, but I like the "Trust" name better.

 

where did you attach the ground wire from the original exhaust when you installed the Greddy or did you jsut remove it all together?

Rigth!! what is the difference? in sound?
from which site can take a GReddy EVO??

 

I installed the Greddy this weekend. If you are not on a lift, it can be tricky getting the exhaust off. I could not get the pipe off that runs up towards the cat and had to take off the plastic exhaust openings to get the tips to slide out so I could get it off. The Greddy weighs about 5 lbs less than stock. It is LOUD. I have no resonator so it is quite loud. Much deeper tone, no more raspy, tingy sound. The vibration sound is totally gone too. I had a vibration tingy sound from 4K-5K and that is totally gone. The ground wire is still an issue. Not sure what to do with it yet. I wrapped it around one of the exhaust hangers for the time being. I am going to try another video soon.

 

I did mine about a month ago, very easy to come off after I removed the 5 hangers and the plastic around the exhaust tips. As for the ground strap while mine ran fine for three weeks without it I figure Mazda put it there for some reason so yesterday I put it back using a clamp similar to this one around one of the mounting struts. I attached the end of the grounding strap to a small section of steel attached to this clamp. I will add a photo of mine later tonight.




EDIT: Pic of what I used.

This website has video and audio for a couple of the available exhaust systems. It helped with my decision, now to come up with the money.

 

I am waiting to get the SP2... coming from Japan to Greece

 

I am going to try the same, thanks for sharing.
