What do you all think of heart throb 4" exhaust, is it annoying when cruising down the highway? What do you recommend that isn't to loud? Will it void my factory warranty?

Cat back exhaust will not void warranty, IMO I would go with a corsa dB 3" exhaust it sounds much better then my buddies there is an after market exhaust data base on here feel free to look it up :)

If you want a quiet exhaust that is deeper than stock I would go for the FR exhaust. I have one and I love it

why would you want a quiet exhaust? Stock is quiet.

& people have said it's a straight they design. Stacy must have been wrong?

Also talking to my gear head buddy @ work. There's a reason for the funnel from the res to muff. Turbos need that back pressure. But I still think DPs are a MUST

Then get the FullRace resonator delete catback. I love mine. The best looking and sounding catback made for the Ecos.

I have the 4" heart throb installed on my truck. We took a 400 mile trip this weekend with driving on the back roads to the highway and I have a little over a 1000 miles on it. I like the sound of the system. I will say occasionally under partial throttle she will get a little loud. But you a sound board and see what you like.

I have a 4" Flo-Pro with their 4" resonator and a 5" MBRP tip. It's not too bad for drone but is pretty loud.

Sounds sweet during start up and under load. Lots of turbo noise through the exhaust.

Hey has anyone felt a loss in low end TQ going with a 4" exhaust? I have a 2014 ecoboost and I had a LET tune ( 91 octane) before I put on the AFe 4" exhaust and it feels like I lost some low down TQ. I have a revision for 93 octane waiting for me so maybe that will bring back that low end TQ lose I feel. Have to get home from working out of town to install the revision.

Thanks

Ok well then I guess this 4" AFe exhaust I have is useless. I have a stock 2013 5.0 exhaust from my old truck laying in the garage. Will that bolt right up to the ecoboost? Maybe ill just get a corsa db muffler and call it good.

Ill also wait and see what my tune revision does for the loss in low end TQ.

Thanks

word on the streets is that 4" has a nicer deeper tone & loses some low end torque while gaining high end passing power.
