MBRP Axle Backs split open under boost on my GT500

[Seer]

The bumper looks fine but when the muffler burst it pushed the bumper off on one side damaging the mounting tabs.

Dude im still amazed that this happened. I mean how could there be that much heat/ back pressure at an axle back. Or r they just that shitty? In for pics of the bumper.

they're not cheap, use a good grade of stainless and sound awesome. But I guess their claims of handling high hp applications are bs.

or some terrible build quality

yea, you are right! Heard good things about them too, The Roush will sound great.

Looks like a pop can that got shot by a 45 lol

Did you have a wot box? Looks like it busted at a welded seam. It happens.Maybe bad set up or a poorly welded joint from the people they buy their material from. Not unheard of from any manufacturer. Hopefully they take care of ya.

Yep, but for their claims of hp, it most likely shouldn't of happened.

Its a none issue on the replacement since summit is taking care of it, its the bumper im more angered about.

I do have a wotbox, but this didnt happen on a shift. I'm hoping the Roushes hold up better though.

Corsa's wouldn't have done that. Sorry about the bumper.

bumper looks good, just the tabs are bent/damaged. So it'll need replaced regardless to be up to my standards.

Looks like they got damn hot through the centers. Combine that with a crap build job and here are the results.

Send me the tips! LOL!

Send me the tips! LOL!

Summit Racing stepped out and is sending me out a set of Roush's tomorrow, and they want these back to send back to MBRP.

im guessing no cats? fuel build up during a shift and pop is what it looks like. i had a set of bassani mufflers do that when i had my lightning, blew those mufflers out the back side though.

wotbox = no chambered mufflers!!
I blew my stock ones up, but they never actually opened just expanded lol
Those mufflers look really thin hmm.

Wasn't a wotbox shift but ya, this really exposes MBRP's "high quality".

WOT box killed the OEM mufflers on mine before I had it.

Well, I hope the roushes last while using my wot box. If not, I'm gonna have to think outside of the box.
