    Does anyone here know what the size of the front exhaust pipe is on the Hellcat? I'm planning on having QTP Exhaust Cut Outs installed and need to know the pipe size to order the right part. I spoke with a sales rep from QTP today and was told that they don't catalogue their parts by vehicle type / model. Any help is greatly appreciated. I'll post audio clips after I have these installed in the spring.

    I want to say it's 2.75". Might search for that great engine article, about Dodge's Paradigm shifting engine. Think that's where I saw it. I know there is a link somewhere here to it but can probably google it faster.

    QTP may not make a 2.75" version? Definitely a 2.5 and 3.0. I'd get the 3.0 and have your muffler shop weld in a 3.0" to 2.75 reducer.

    I have those on my 66 chevy hotrod and they are a blast. Any problems with a computer car and not enough back pressure? If not I will put them on mine.

    that looks nothing like mine made by QTP but mine are over 5 years old. They still work perfect. Mine are for round 3 inch pipe. I have a big cam in my 66 and it really sounds good.

    I don't want the low profile cutout...I want the wide open circle...in 3.0". Dumped.

    Does the "wide open circle" type hang down further than the "low profile" type? In other words, are there clearance issues underneath with one type v/s the other? Thanks!

    It's already loud. My bro said he could hear me starting up from 1/2 block away. Punching it going up on ramps scare the crap outta birds on the wire. Literally. :eek:

    I agree, it is loud at start up. I just want "something more" for "special occasions"!

    Mine do hang low and bolt to the headers. That may be a problem unless they make a weld in style

    Thats why i went with the low profile cutouts. The car is low to the ground. I wouldnt want to get stuck on a speed bump lol

    I talked with sales people from Summit racing which handles QTP equipment. I will be calling QTP directly tomorrow. It appears that the Low Profile type of cutout requires use if a plasma torch or a Sawzall to cut out an oval shaped opening into the pipe. I really don't want to do that if something "bolt on" becomes available. There's another cutout which is 2.75" but it's specific for the Boss 302 so it likely wont work either. Hopefully more info tomorrow. The best case scenario would be if the "rumored" MOPAR exhaust dump becomes available soon.
