I’m wanting to get a set of headers and mid pipes for my 05 300c. I have the stock exhaust currently installed and plan on adding mufflers and new tips as well, just want to do the headers and mids first. My plan is to put a Procharger system on it within the next year. So the big question I have is with long tube headers will I need a custom tune or will my trinity t1000 work? Also is there any issues with clearance on a lowered vehicle I have BCR coil overs installed and the car is dropped about 1 1/2”. Here’s a link to the headers I’m considering

And the mids

Also I assume the cats will be relocated so I’ve got these as well. BBK 1118 Exhaust Pipe https://www.amazon.com/dp/B00J2RQ3US/ref=cm_sw_r_cp_api_i_NIfPCbR014JB2

Any feedback or advice is extremely welcome and very much appreciated. Thanks in advance.

Stick with an equal length design for the true gains that come with long tubes. I went with Kooks and they are fantastic.

Typically the mid pipe is specific to the header and is sold in a kit with the headers.

A custom tune will help, especially to turn off the rear o2 sensors to avoid a check engine light.

Use new OEM header bolts and OEM gaskets, regardless of what may come with the headers.

Ok, I decided to go with these bank headers to match the mid pipes. I don’t wanna go catless so I’m gonna get some high flow cats, with the mid pipes I’ve selected will they bolt up to the cats or will this pipe delete the cat entirely. Sorry for the silly questions I’m just a complete newb with this stuff.
