Hi, so just recently decided to change my whole exhaust set up I'm running ( Flowmasters with a muffler shop X pipe lol )not the greatest.... Anyway I was looking into getting a whole set up I'm talking long tube headers , intake, to exhaust. Any recommendations for a 2015 v6? Any idea if an off road X pipe off of a 2014 would fit my 15? Thanks.

You might have to have your local shop weld or make you a mid pipe for the headers

I was thinking Roush exhaust, off road X pipe ( if possible ) mid pipe, BBK long tube headers, BBK intake , tune. I hope I can get that exact set up.

Based off of others set ups most people complain that the roush with bbk long tubed sound to Rice. I'd suggest an exhaust loud but not to loud so it doesn't sound obnoxious in a bad way. Maybe straight pipe with headers.

BBK has their H-pipe for the 15 finally available.

Here is what I suggest from experience.

A thing to note: You WILL need a tune if you get LT headers. A lean condition is created in the 2.75-3k RPM mark with these headers. A tune from unleashed tuning will help the issue. It will not fix it completely though as there is still not enough tuning support for the 3.7. In the future though the issue should be easy to correct.


BBK long tube headers
BBK CATTED H-pipe
Stock catback resonator
Axleback of your choice

Depending on your axleback you could add in 12" resonators to clean up the sound some more if you find it to be to raspy. Straight through glasspack style resonators will not decrease volume much at all but will clean up some of that high pitched rasp that might be present. The same can be said for the high flow cats in the H-pipe.

Lol troll much?

Some guy had a v6 with straight pipes and headers. It sounded pretty good IMO. Probably the cheapest way too.

Haha it was loud as hell.... To loud for me.

I ended up with this setup. (I added high flow cats after this vid which cleaned up some of the rasp)

Headers, no cats, stock resonator, magnaflow competition axleback.

(the sound was overwhelming the mic)

No lie that still sounds good I'm planning on getting my long tube headers soon and I'm nervous cause it's with a off road mid pipe so it's going to be loud so far I have bbk resonator delete with roush axlebacks!
