    Hey corolla forum
    I was reading through post and I saw some posts about weapon r headers and I searched it up and also did live chat with the website assistance but told me there is none... I was wondering which one it is? I would love to get one for my 15 corolla

    I think they only advertise up to the 2013 model year but should be the same.
    Also check DC headers.

    Thanks Chris! Do you have a header too? which one is better because I hear Weapon R last long and function better?

    I don’t have one, yet. But also looking into it!

    I know that Weapon-R makes one for the 09-14 models. So I’d think they would work with the 15 because they’re the same as the 2014

    If they go on the 15, what about the 16?

    It says 2009-17 so that would be a yes according to Weapon R. I just put mine on and it really helps the whole power band. CVT still sucks but oh well highway pulls are much better especially with the Pedal Commander.

    Guess I’ll be placing an order this week. Do they come with gaskets?

    It says on the site that all race headers delete the cats. But in the picture on the site it just looks like the front part of the header that connects to the first cat. Did yours come long tuned when your ordered them?

    No mine came just like the picture. So the CAT stays. I deleted the secondary cat after the O2 sensor. It says race header because it does not have an CARB EO number. I tried ordering it from different states and both rejected shipping the header to me because of that. Then I called Weapon R directly and asked if they would send it to me and they did but I had to pay the full price instead of 100 bucks cheaper in the other 2 states that I tried ordering them from.

    It comes with an "O" ring gasket for the lower part and 2 bolts. No gasket for the top part of the manifold.

    Oh alright. Good to know. I actually did the same. Got ride of the second cat behind the sensor and took the resonator off. And has a borla axel back. I think I'll just leave the 1st dat on. It's deep already. And then the new headers will just be the last part for my exhaust!

    Yup that is what I did except I put a magnaflow 4" inch muffler (deeper tone) with the J2 exhaust axle back. I think at this point it would be too much work and too much $$$ to get rid of the CAT especially in California.

    What did you use then?

    I re used the same exhaust manifold gasket. The mechanic who installed the header said it was not damaged and did not need replacing. We did up using the other items that weapon r sent. Exhaust O ring and spring bolts.

    Any noticeable difference with the NST pulley?

    For sure. I noticed right away. Granted I have the CVT, so I need all the help I can get. LOL. I re used the OEM belt just had to tighten it all the way. Revs a bit faster.

    Check out a p2r throttle bottle spacer added quite a bit of tourque for sure, I have about every mod possible besides a turbo or supercharger, and I’ve barley noticed anything, definitely needs a tune

    Just wondering, what exactly do you have for performance mods? If you could, could you make a list.

    Weapon r header
    Straight pipe to j2 cat back
    Weapon r intake
    Jet performance mass air flow sensor
    Nst light weight pully
    P2r throttle body spacer
    Pedal commander
    Basically every bolt on but next I want to get a MWR light weight crank shaft.
    I have a 2016 CVT Model
    There’s definitely a difference but not worth the money for a CVT kinda my fault still love the car though!

    Yeah, you'd probably notice more of a difference in a manual. I think a tune would help a lot though. As far as the lightweight crank, would you want to install this on it's own or with some of the other MWR 2ZR internals. I'd think it would be better to combine it with the other upgraded internals since the engine is already apart but it also costs more money.

    I just installed it with other bolt ons and let it be. I have 3k miles on it and no issues. If issued do arise I have the extended Max Care with Carmax. bumper to bumper!
