I think they are welded into the piping...a cutout installed before the cats would certainly fix this issue however...and that way you wouldn't even have to get under the car...just flip a switch.

Regardless, it pisses me off that we (tax payers) are going to pay for emissions controls.

Guys, The scoop on the factory mufflers is this, they sound absolutely awesome with our system. This was a concern of ours but it turned out to be huge relief. The sound could best be descibed as a cross between Flowmasters at idle and part throttle to Magnaflows when you're hammering it. What's great is that although there's quite a bit of volume, there is no drone. The catted portion of the system is not welded to the X-pipe.

Nick - have you guys experimented with aftermarket and OEM mufflers, power-wise? I'd be interested in seeing if there were much in terms of gains.

Thanks and great job

Two questions:
1) Can we hear them?
2) Will they be available without cats?

Radz, We dyno tested the G8 mufflers, which happen to be much quieter than the Camaro's, and only saw a 3 RWHP gain by removing them altogether and dynoing with open exhaust. I expect these mufflers to be at least as good as the G8's if not better.

Wavrun, I will have a sound clip hopefully next week as we have another Camaro coming in. You most certainly can buy the off road catless system.

Hopefully towards the end of next week because I am coming back to Long Island the middle of next week for a mini-vacation. I would love to come check these out!

Sooo....no before and after dyno #'s? I'm guessing stock it made 355-365rwhp? Which would mean now it makes 405-415 rwhp with just headers and a tune? Please elaborate.

Yes I do have a before and after dyno graph. It was scanned earlier today. I'm waiting on Tom to post it. This vehicle made 383RWHP and 379TQ SAE corrected. It finished off with 433RWHP and 424TQ.

IE: If it doesnt have a CARB number it wont be legal in CA. Hell, it wont even pass the sniffer test WITH the cats on it there.
It's true all long tube systems are not technically street legal it really depends on your state and their testing procedures. Most states don't do sniffer on obd2 cars just computer scan no codes= pass the codes are usually taken care of by your preffered tuner.

These were done with 1-7/8 primaries we did not make pulls with a 1-3/4 setup this car was trailed to us from the dealer before the owner took possesion we promised not to drive it other than to test the system there was no need to wring it out with another set. Once guys start installing them you will see where the other sizes shine HP wise. Dyno graph just posted in new thread with installed pictures.

No such thing as stupid questions no sound clip there was'nt time we did'nt have a video cam,era handy and we were on a real tight time frame. And they will definately work on an auto

Those are the cats we use they are made by an OEM supplier and are nearly bulletproof. They are 200 cell metalic matrix cats the highest flowing cats currently available with this kind of durability

other than Cali. most places tend to be pretty leniat concerning a visual inspection especially on a brand new car.

Kooks has something similar on many of their LTs, but they're not quite as good, from the looks of them (they have true high velocity merge collectors for an additional cost though for some models, last I checked). Anyhoo, these are great gains! I didn't really think they'd be this high, but considering the numbers - WOW! Has ARH mentioned if they are going to offer additional sizes and stepped primaries for the 5th Gen too?
I believe the OP was talking about the connection area at the rear,to the axleback but you are correct that high velocity merge collectors are standard on this system as well as all our other systems because they work there is no cost spared to bring you the best system possible. We will be doing primaries in 1-3/4, 1-7/8 and 2" we can do steps in those sizes also I doubt many will need a 2" header for quite awhile though

You can drive without a tune without hurting anything but you will be down on power and will more than likely see a CEL for cat efficeincy(sp)

As of now I doubt it but if demand is great enough who knows the X-pipe makes better power and is easier to package in this car

You can get them coated of course but we don't push it because it's not needed

Best part of a good stainless header is the beautiful copper color they turn after some heat cycles!
