My Brola XR-1 exploded today
5 Attachment(s)
My Borla XR-1 finally gave in today ..... It was sitting after a SDJ header. I probably had it on the car for maybe 2 yrs. Pictures will take a thousand worlds.
I am thinking I should go back to Racing Beat's mild steel so this does not happen again ..... |

Do you guys think this is due to heat, too much exhaust movement or defect? Current exhaust setup is SDJ header -> Borla XR-1 -> Stock cat back. |
i would throw a magnaflow in there. u can pick them up at a reasonable price and they last too. thats what i have and i know a few others that have done the same. plus it quiet's down the car too
|
Holy Shit!! I'd give Borla a call. I bet they'll replace it for you.

Looks like there is some tuning and running way rich issues
|
Unless my injectors are stuck open, a/f should be ok.
When I was at the dyno, I tuned it to 13.5 with a wideband on my S-AFC ... Hmm ...I don't get flames and I don't get pops... maybe indeed one of the injectors are stuck open? This just happened after a lapping session. |
My guess would be exhaust movement as the culprit. The exhaust is soft mounted, yet there's no flex joints in there, so all that movement's taken up by flexing, mostly in the weakest part, which would seem to be that muffler as a pre-silencer.
|
I guess you got what you paid for? Any compaints? How long was it in service? Would you buy another one considering the longevity of the part? Is something blowing up in there? I would suppose once it cracked that some air got in there during deceleration and the exploded under throttle?

Hard to tell from the pics if that's a crack or a tear. If you get a brittle-like crack in a ductile (flexible) material - which normally bends/etc. not cracks - then it came from fatigue. Fatigue would be from the thing flexing back and forth, or repeated pressure fluctuations. If it ripped apart from too much pressure, then it should tear apart lengthwise, which didn't happen. Though maybe the metal's thinner in the other direction; it did break along the letter "L". I'm more engineer than car guy, btw, these are just guesses.

I blew one in the same manner on one of my Turbo IIs back in the day.
|
That muffler tore open. Borla should be able to replace it for ya.
|
Borla will warranty that. I think it's too close to the headers, and you have no flex allotment. Flex pipes or donuts. I've had one of those on my car for about 5yrs. Those are some of the best pieces of sound control for vehicles on the market today.
