I just put on a MBRP cat back that relocated my muffler under the back passenger seat. I haven't had it on a week or so, but they advertise a 9 hp gain.

I have the dual gibson cat back and they adverise 15-20 HP gain , but really i only felt about 1 or 2 hp gain


hope to read from others experiences

I am also looking at this and wondered if you have to relocate the evap canister? would the muffler skid and evap skid still work without any more mods?

Robar

You don't have to relocate your evap can. Mine is still in it's original spot. I can't say about the skid plates though.

In my opinion

1. the best plugs are the E3's

2. the best wires are Taylors 8mm

3. JBA for the Headers

4. Banks for the Cat Back.

x2 on the E3's.....

Careful of the E3 plugs, I had a little over 2,000 miles on mine when they started throwing misfiring codes. Not to say that I couldn't have had a bad plug but there have been a few others on here that mentioned the same thing. I put the stock recommended Champions back in and I have been running fine.
