i loved my ecode testpipe yea its a bitch to get on but they all are

 

any input on my question though?

 

there really isnt a difference between the two.... Id do it all at once less hassle that way

 

So 2.5 inch, or 3? and is it going to mess up anything have a 2.5, or 3 inch testpipe going into a 2.36(60mm(neuspeed)downpipe to 2.75 inch piping?

 

its not really gunna do anything with the stock turbo if you had a bigger turbo you might need to worry about the size differences, sounds like the neuspeed dp is the down point id get a 2.5 dp from techtonics

 

should i get a 2.5 inch downpipe with a 2.5 inch cat delete or 3 inch? thanks!

 

well they say its best to stay the same diameter the whole way but i had a 3'tp and 2.5 everything else and it was great, I would probably go with three if your ever gunne upgrade turbos but if not just stick with the 2.5 and a 2.5 DP

 

I want to go gt28rs someday, but not right now...want to do suspension stuff first
