I was driving tonight and encountered some unexpected road construction (dark road, no visible signs) Well, there was a pretty good dip and I bottomed out on the flexpipe. On the way home, I noticed a loss of power in boost but it could have been in my head. The car doesn't sound any different, but it wasn't able to break the tires loose like it usually does.

At home, did a visual of the downpipe, exhaust manifold for cracks, as well as the couplers on all the piping. Other than the damage on the flex pipe, I couldn't find anything. Will get the car in the air tomorrow to check again.

Any ideas?

 

its fine

 

If anything, a cracked-open flexpipe would make it a bit quicker - leaning it out a bit towards 14.7:1. Its unlikely the interior of the flex colapsed, but you should really check it out. Hopefully you put a flange somwhere close to it, as I can't see one.

A flex section is usually an inner and outter mat of SS braid, and a middle core of ribbed SS.

 

On update, I drove the car last night. The car makes full power it seems, but immediately after letting off the gas in 3rd, I heard kind of a "pop pop!".

I am getting it flanged eventually, it was rush job just so we could get to the dyno in time.

 

That is like a scratch man. You should see my flex pipe. Those things take massive abuse even if the wire weave are all broken on the outside it still have the interior sheild kind of a like flexiable straw.

 

Cool, thats what I like to hear. I just hope I didn't catch the flat edge and crack/break anything up at the mani/turbo.

Kind of worried about the backfire but I'll inspect everything in about 4 hours.

 

ya, thats how mine always look after week one...by the time I replace them they are flat on the bottom with no braid left. You might have cracked something higher up though causing the popping.

 

On 2nd look, everything seems legit. The steel mesh looked like it took most of the impact, so the swivel pipe underneath is ok. Inspected the mani again, as well as the downpipe. Nothing busted, so I went for a test drive, and everything is a-ok so far!

Weird night!

 

Its in your head. It looks fine.
