You guys happy with your exhaust?

jimmystoys · Apr 14, 2017

I have 4" Flo Pro on my 2012 since spring of 2012. All very rusty now. Unfortunately, it rains and snows on occasion up here in B.C lol. Rusted through 3-4 clamps at different times on a long trips. Not fun when your showin an towin. Waiting for the whole system to collapse one day. I really don't mind paying more for a better system...if there is one. Just want something clean and reliable. Anyone with advice, much appreciated.

five inch in manitoba that's a month old and I've got rust starting the welds already. Hope to get a good couple years out of it and then I'll just go to napa and buy myself some five inch exhaust piping and bends and make a cool dual set.

Well I thought mine was suppose to be stainless. Where I purchased it says nobody really cares much about the quality of their exhaust. I realize theres poor quality and good quality stainless out there. Guess this Flow Pros not very good. Very disappointed. I had MBRP last time with no issues.

Flo pro and most companies use the cheaper 409 ss that will surface rust quick. Flo pro seems to show surface rust quicker than mbrp from what I've gathered online. You can spend the money and get 304 ss if you want high quality with no rust at all. I just went with flo pro aluminized and it looks brand new

4" Diamond Eye and happy.

A little footnote: 409 SS is not going to rust out but it will show some surface hazing of rust, but it is more heat tolerant than 304.

Flo pro is renowned for rust. I have a friend with a 150 and his cat back flopro duals lasted a year.

Their kits fit so nicely tho

My aluminized 5" flowpro looks great after 2 winters plowing. I figure it will take at least a few more years to look like crap

4" MBRP turbo back w/ 9" slant tip. Got a lot of laughs (re tip) until it was bolted up and I didn't expect it to make much of a difference with sound but it's pretty dam grouchy under even light loads. I was a little apprehensive reviewing how it all assembled with slip joints and almost returned it upon discovering the down pipe was at 3.5" when advertised full 4". Let's just say after installing myself in the front yard I'd bought the MBRP boys a beer over that half inch o.d. Been rolling over a month and nothing has let go or began rattling so all my expectations were either met or exceeded. **Only issue- make sure you are there when delivered or inspect upon purchasing as if any of the endos are bent or flattened during shipping it turns a fairly easy install into a major aggravation.

Hate to say it but If you don't wash your truck two times a week in BC during the winter, everything is going to rust. I didn't wash my truck for a week and a half at Christmas, when I visit my parents and all sorts of parts of my truck have rust spots now. They use more salt than the salt factory itself...

NMSVT · Apr 17, 2017

What ever route you decide to take (I would recommend stainless) make sure it's 5in!!

jimmystoys · Apr 17, 2017

Ya the amount of salt was crazy this year. We had weeks of snow this time where we only see a couple of days at best for the winter. Doesn't the salt react with aluminum too?

Yes, it creates aluminum oxide, which causes corrosion. I have the aluminum model of the 5" Flo Pro and it's getting a little tired looking now too.

I have a factory down pipe to a SS weight loss pipe, to MBRP SS duals. Fits perfect, looks great, sound great. I honestly don't see the need for a 5in exhaust.

That's because you're only running a paltry 600 horse or so. Double that and you might find the larger exhaust useful. 4" is plenty big for us common folk.

Self etching primer and some hi-temp for the top coat just to be sure. Been holding up just fine but hey VA nor the Lower East Coast really isn't in the Rust Belt.
