What are you guys using for a y-pipe with the SLP headers? I am running the stock one, but want to get an OR y-pipe. I was thinking about getting the one out of summit, but wanted to make sure I wasn't missing something.

thanks

Stock y-pipe with the left cat removed. Can't beat the price.

 

I was planning on keeping the stock y bcuz there is talk about emission testing. Thanks though, I might try to find someone who is selling a stock y or something. I should know this, but how big is the stock y, is it 2.5?

 

Stock size I believe is 2.25" from each manifold to 3" where they y together. You'll make a little more power with the slp ory pipe if it is 2.5" from each manifold/header. Not enough power gain to justify the performance increase imo. Thats all. I understand where your coming from though about emissions.
