    CT4-V Muffler delete + Downpipes? Anyone do this?

    Just an update on this mod after a little road trip. Not a big one just did about a 1000 miles but have a total of about 2400 miles since the mod. I'm extremly happy with this setup. I installed mini cats when the DP's went on and got a code after about 50 miles or so. Reset with the JB4 and...

    CT4-V Muffler delete + Downpipes? Anyone do this?

    There was a request for more vids. Here it is on a backroad (closed course of course). Not getting crazy just a spirited ride. I may need a mic because I don't think this audio does it justice. Nor the PDR audio. The clicks are from the mount my phone was sitting in.

    CT4-V Muffler delete + Downpipes? Anyone do this?

    Yes. A significant difference in the way the car pulls now. As stated in above Posts I was contemplating going to a 5vbw but now I think I’m good with my 4vbw. Last thing I will probably do will be the oversized air box as it seems that gives it another bump. If that bump is a step up like...

    CT4-V Muffler delete + Downpipes? Anyone do this?

    Just wanted to report back. Just got my downpipes and TB installed. Now this car is how I want it!!! Butt dyno notices a significant difference and the car sounds amazing. The exhaust delete wasn’t enough and I don’t think the DP’s by themselves would have been enough. I think this combo is...

    What did you do to your Blackwing today?

    Agree the CF under the hood looks sharp. I did the cover and the front radiator cover (we did opposite second pieces). I been wanting to do the air box but was being wishy washy on oversized or stock. Also have heard some guys getting rough idle with the oversized after some time. If you...

    What did you do to your Blackwing today?

    Did you do the oversized air box or OEM? I’m picking up my car tomorrow with the last of the blue belt installed. I’m thinking about doing the oversized air box now that I’ll already be into CEL’s with the DP’s. I’m assuming you did the oversized MAF since you commented about enjoying it on a...

    Pics of your Blackwing in regular parking spots

    At the local grocery store picking up goodies on the way to the drive-in. Saw a 5 and parked my 4bw infront of it. I can tell the 4bw from the ct4 but wasn’t sure if this 5 was a bw or not

    CT4-V Muffler delete + Downpipes? Anyone do this?

    To be honest I don’t think I would do the JB4 again. Although it will be helpful in deleting the codes I get once I install the downpipes. Though the assassin would be a cheaper and quicker option. To be clear I have done the air filters, cold plugs and exhaust delete only so far. I don’t...

    Ac, Nice seems we flip flopped from Ducati to Aprilia in opposite directions. The R6 was probably my favorite at least on the track. I have a 21yo son on a Daytona 675 and I didn’t want him trying to keep up with me on the Tuono. That’s why I went to the Hyper. Though the hyper is super fun...

    Congrats! What bike you have on the way? I been riding street since 14years old (50 now). I’m way more of a bike guy than a car guy. Raced at the club level in my 30’s was a trackday instructor for a few years. I would highly recommend Keith Code’s (I did all 4 levels of his school twice)...

    CT4-V Muffler delete + Downpipes? Anyone do this?

    Nice! I’m getting the TB and the cat less DP’s next week. I’ll just deal with clearing codes with my JB4 until I buck up for the full tune. Hoping it won’t be too annoying with constant Cel’s. I still have a hard time believing no one can come up with a work around for the o2 sensor. Per...

    CT4-V Muffler delete + Downpipes? Anyone do this?

    I have done the muffler delete on my 22 4BW. I found vids of muffler delete and of down pipes catted and no cat. None of both mods though. Anyone done delete with DP’s? The delete definitely helped but still not enough for me. I’m thinking of trying tapout’s catted pipes with the delete...

    My Aerolarri's for my summer tires

    Those look sick! Think I’m going to have to pop for the same setup. How did you find a discount code? Biggest problem will be the wait.

    Ct4 v Blackwing air filter install

    In my experience WONT In my experience WONT TAP will not steer you wrong. I have like many done the green filters (oiled) and no issues or CEL's don't know about the throttle body but would be interested to find out.
