I was looking at the two exhausts at greddy.com and noticed that the evo2 has one more piece than the sp2. Does that mean the evo2 is fully stainless steel while the sp2 still uses one of the oem parts? Im just curious on this one or maybe its just the picture thats throwing me off. Also do the 2 differ too much as far as sound comparison? I dont want something too loud but not quiet enough where I dont notice it. I already have the kn cold air intake so im guessing that will have a role in this......

Also if you had a choice between the two which one would you choose?

 

the pictures for the SP2 arent the correct ones i guess....accord catbacks are all 3 pieces (as far as i know)

 

I'm pretty sure my SP1 cat-back was a 2 piece. From the cat to right in front of the right rear tire then the muffler hooked up there. I could be wrong though its been a little over a year since I put it on.

 

Is there much difference as far as sound between the two?

 

The SP1 is a 3 piece design I have one

 

all accord (at least 4th and 5th gens) that i know of have a 3 peice system, because of the design of the stock piping/ hanger location + factoring in shipping....
combiing the 2nd piece with either of the other two would create MAJOR shipping and instalation problems (if the car is only on jacks/ramps).....3 piece system also allows for more flexibiity in fitment
