I just bought an 03 cobra mods are 2.75 pully, ported blower, CAI, and tune. It car made 469rwhp and 489rwtq. IT still has the stock exhaust , but with flowmaster mufflers welded in place. I want to add an offroad x-pipe, but will I have to have it retuned or Can I just get some o2 simulators? Thanks a ton, Im new to these cars, so any info is great.
question about removing cats and tune?

Your tuner can turn off the O2 sensor's.
Yes the car will need retuned and then the tuner can turn off the rear 02's so you wont need 02 sims or anything.
Do it right or dont do it at all, A tune is going to costs you $100 if you have the handheld or $500 if you need the handheld. The engine is $5000 from a junkyard.....

dont go 02 simulator route, they are junk, expensive, one will fail and you will be purchasing another pair to replace the broken one. get the tune adjusted, dont waste money on crap, simulators dont last, they are junk
Very rare to hear of someone getting a retune with the addition of an off-road mid-pipe......The vast majority of folks utilize MIL Eliminators when they go this route.
Why go out and waste $60 on buying MIL eliminators when you can have your tuner easily turn off the rear sensors?
Saves you time, and money :beer:

Well......my tuner is 123 miles away and I'm running a Diablo Revolution chip. I change to my MAC off-road H pipe when I go to the track and then put the Magnaflow high flow catted midpipe on when I drive on the street. I bought the MIL Eliminators for $30 off the SVTP Market Forum. I guess this is my rationale.......
The vast majority of fellas that I know of that are running an off-road mid-pipe, use MIL Eliminators. But there are certainly different ways to approach this.

My Whipple at 17# upper setup started with a mag catted x and mag catback way to restrictive for my car. I had a Mac O/R Prochamber installed then put it back on the dyno it ran way to rich my tuner adjusted things and picked up 20hp and 25tq and im still at about 11.4 A/F up top safe street tune 17* timing I would check your tune after removing cats or you may not see any gains, my rear o2 sensors are turned off. Mac O/R prochamber and Mag catback is the shit.
I just had my stock eaton tuned today at 457hp, 474tq on a 2.8 pulley, JLT CAI, Bassani o/r xpipe with mil eliminators and a borla stinger catback. Sounds great but too loud for my taste and wanna hear the whine more over the exhaust. Tuner says if I install the stock catted h-pipe, it wouldn't need a re-tune. Can anyone confirm this before I swap it out?
