    Took the car out for some toying around after the install, and i must say the car is nastier with these offroad pipes. It sounds completely different under wot and just cruising. Its much more responsive its like a different car now.. man I'm so glad i did this. It’s like falling in love over again..thanks again op..

    If I needed cats for emissions I'd get some flanges and make them bolt on. Use them to pass the test and drive around legally. In half an hour you can unbolt them and bolt on a set of test pipes. Its so much easier to change out than slip on exhaust parts.

    This is true, Whipple spent a lot of time working on the COT part of their calibrations. Lund melted your cat. But hey, you hit 12lbs and had moar powa.



    Whipple has stated that the heat builds so quickly the calibration will hit COT protection before one can complete a 1/4 pass. Tuners that just stare at AFR like its the bible are the problem. Do you think for a second guys like Greg Banish could not calibrate a boosted car to be safe.



    geez.

    I'd love to see a vid. I am still not convinced that my 2 bottle style resonators are the right course of action here. The sound you describe is exactly what I am looking for.

    Exactly what I am doing.

    My cell quality doesn't give it justice, but here is a quick video.

    Perfect. I’m going to buy that same resonator and have an exhaust shop fab it to my x pipe. I hate the rasp I have now and after the catless headers go on next week it will be out of hand.

    I believe the Magnaflow 12468 and 12469 are the same resonator, with the 8 being 2.5 inch and the 9 being 3 inch. Either one will replace your current X-pipe.

    You will be very happy !

    That’s what I thought but if you look on the magnaflow website they are different. 8 is an X 9 is a Y. I don’t see any issue with flow either way. I ordered 12468 .

    You posted you had multiple misfire codes. How close were the #s on the leak down and compression test.

    I am a little sea sick now. LOL Seriously, Thanks for making the vid!

    Very mellow, and almost stockish from inside the car. Usually rev videos on a phone are the worst. I am sure it sounds even better in the wild. I may just have to grap that 3" resonator you have.

    Thanks Dominant1. Appreciate that. I bought a new 15 block from ford for 2 grand after they take my core. Of course my old block looks good. No scratches, dents or damage but I still didnt wanna take a chance on my old block. Might be something we didnt see so I paid 2000 grand for a piece of mind smh. Heads getting tested at the machine shop car should be put back together at the end of the week

    Still trying to figure out if it was tune that fucked up my driverside cat or it just failed on its own. Shop swears up and down it wasn't the Lund tune. The passenger side cat looks brand new. Why would one side fail? Just doesn't make sense to me. What do you guys think? Tune or it just failed on own?

    Both my cats were fubar its not the tune its the cats themselves. Lund has tuned tons of boosted cars with cats..American racing headers will tell you that their cats cant withstand extended periods with boost. Remember The arh exhaust system has a lifetime warranty on their products they’ll keep replacing them as they fail..but they wont cover a broken motor from it.

    Do the break in period for 1000 miles and see what how it feels. Still waiting to get my car back. Should have back this week
