Well gents, I'm finally done. Took me almost the whole weekend, but I am now running a Mac cat-back and a O/R Prochamber. Header bolts broke free pretty easily, after a good PB soak. 02 wire didn't want to reach on the drivers side, dunno if its just the 04's, but I had to pull the harness off the plastic bracket and really stretch it to reach the upper 02. With all the pieces between the cat-back and PC....adjusting was a PITA, and still not sure I have it all adjusted correctly, waiting for leaks and/or knocks I guess. I have many many cuts, and a really bad gash on my thumb, and I'm freakin freezing from laying on ice cold concrete for 10 hours. So, install wasn't too bad, but ran into more problems that I expected, and had fewer problems with the things that I expected to have problems with. Go figure. I'll do some pics and vid clips tomorrow....I'm too damn tired to even clean up my tools.

SOUNDS AWESOME! Very mean, deep, rumbly at idle, livens up at higher RPM's. Haven't had a chance to hear it from the outside myself, but I think I"ll be happy! Seems a bit quicker, almost like the tach climbs faster and more freely....its was drizzling so I couldn't really go too crazy.

Conclusion, MAC rocks (hope the bastard don't rust next month!) and I'm proud I was able to do it all myself being a novice (I need to find some wrenching buddies)

*edit* The damn thing stinks!
 
Congrats.

Hope you got the coated prochamber, or sprayed some high temp primer on there.. or you can expect to see some rust in a year or so.

Also, yes it's just the '04's that need the lengthening on the drivers side front sensor.
 
congrats man, Im a fan of mac flowpaths myself. I'll probably get tired of my new Bassani in a year and the Flowpaths will be next with an O/R H-pipe. Enjoy it :nice:
 
Thanks guys, feels good to accomplish an install. I got my flowpaths from Partshopper along with the Prochamber. I got the 3.5" tips, look at Partshoppers MAC stuff and you'll see the part number.

:rlaugh: Sorry, just struck me as funny. I'd hate to see what you'd call a bad install... Seriously, I applaud you for making the effort. I shouldn't laugh, crap like that happens to me all the time. What takes 2 hours for others usually takes me 3 or 4.

So, congrats, and btw, the smell will burn off in a couple of weeks. :nice:

On my 01 I spliced into the o2 sensor and added some electrical cable and it worked just fine. Looking forward for some sond clips.:nice:
 
DOCG2828, when did you order you catback? I placed an the same order with partshopper last wednesday and they said that they're out of mac catbacks so they ordered it from mac and now i have to wait another week. Just curious
 
Yeah don't worry DOC my driver side front o2 hasn't been in the clip for almost a year now no problems nothing can get closed to it.
If it's stinking yeah I bet you got a coated one. smell goes away. NOW for some slightly bad news if you scrap it on pretty much anything that stuff comes off if they are at temp so take it easy.
Could've been worse you could've gone for a header install too. UGHH.
BTW just so you know the prochamber makes it pretty much impossible to install a Driveshaft loop and have it visible for tech at the track. hence the reason mine went bye bye. :(
