Well, I've got 153k miles on my 2007 Dodge Magnum with a 5.7 Hemi.  I'm coming up on a smog inspection this month and I HAVE to pass that before they will renew my plates.  Which personally I AGREE WITH - which I can't do with my system throwing error codes.   It's throwing cat codes - meaning my catalytic convertors are completely worn out and not doing their job.

But a $2000 installed price is going to hurt.  A LOT.

I've been getting a few errors over the past few months.  Generally after I get a new fillup of premium fuel, which is the ONLY fuel I run in my Hemi.

I'm one of those people who would rather fix it right the first time and not have to go back and fix it again a few years down the road.

I suspect I will be looking at FlowMaster, MagnaFlow, Borla, Corsa, Heartthrob or one of the other name brand exhaust systems out there.  Stainless steel, mandrel bent, all the bells and whistles.

That makes sure that the system FITS the car with no 'adjustments' to the installation or additional parts needed (like hangers).  I want a complete system.

I suspect that I will also be replacing all the O2 sensors.  ALL FOUR OF THEM...

SO, that being said, does ANYONE have a direct example.  Doesn't HAVE to be Dodge, though it would helpful if your ride IS actually a Dodge so I could understand the overall process.

thx

I went to my mechanic and he checked and CLEARED the error code (0430 - which is passenger side cat code) which I've always attributed to a failing cat.  Or perhaps some bad premium fuel.
 
After I drove it for about 15 miles I got another check engine light.  I figured it was throwing another cat code.

So I went to my muffler guy, who has done work for me before.

HE checked the codes, and this time it was an 'oil sensor' error  0520 for low oil pressure.

Then we checked the cats and he said they looked fine.  Except the 'flex pipe' that is on the lower side of the cat.  One of them had been crushed and leaking and the other one had just a minor ding it in.  He only had one on his shelf, so I told him to order me two new ones and call me when they come in.  They will be replaced tomorrow.

I already had mandrel bent, stainless steel pipes WHICH already an XPIPE in it, so I didn't need to change that out.  Very happy with that.

I also had him swap out the mufflers (two in one unit).  While it flowed OK, I wanted something that flowed better.  So I went with a pair of Magnaflow 44's.

I had him leave the resonators in place so it would be quiet - they were no restrictions in them.

Stills sounds quiet, and runs really well with perhaps a little more low end.

Cost me $432 which is way better than the $1500 or $2k I was expecting.

The flex pipes will be another $250 installed ($125 ea installed).

Over all, I will get a repaired system for under $700.  Can't beat that.

Well, I got the two flex pipes replaced.  It appears to make a bit of difference.  I don't hear it on start up like I used to.  Kind of a short raspy sound as it starts the engine, given the small air leak in the pipes on the back of the cat.

It cost me $270 with taxes added.   So that is basically $700 to hopefully fix all the exhaust problems.  THEN I will get it run through emissions testing.  Once that's done, I can renew my license plates.

But the car has been needing this to be done since I purchased it three years ago.  I can't complain.


Hopefully nothing else goes wrong.  It shouldn't.  I maintain my vehicles to a high standard.  Always have, Always will.  The only reason I had not done this is because it did not SEEM to be having problems.  Until it started throwing cat codes about two months ago.  With the holidays, I figured I would wait, as I knew my plates were coming due.  So two months later, it's all fixed.

So Wallew, did you pass inspection?

Nice to see someone that prefer the right way, instead of the fast and cheap way.

Indycars,

Actually, yes I did pass inspection.

Plus I recently put in a new set of coil packs.  NOW it's a screamer.  What a difference.  And for $400 shipped to me.  So the cost wasn't bad and what a difference it has made.

Glad to hear that the fixes work. Flowmaster and Magnaflow both have a extensive availability and are popular. Saving a little $$ helps too.
