After an inspection of the original equipment exhaust system on our SRT-10's it appears to me that this is a well designed system. What advantage would there be To a magnaflow catback? Why not just add a magnaflow muffler to the original system? :confused:

well this could be done, but then you would have to pay someone to install and weld.plus with the magnaflow you get stainless pipe and new corsa looking tips, but if you have a wire welder, you definitly would come out to the good. :)

Thanks Stinker, I was just wondering if Magnaflow had different pipe diameters or if they offered this and if anyone had done this B4. ;)

Milo55,
You may be right about questioning the catback. The real power increase comes from headers and high flow cats. Of course, if you install headers, high flow cats, and 3" midpipes, you don't want the smaller factory pipes in the rear.

Best bang for buck is delete the second cats or even all four. Really helps the sound a lot also so no catback is needed.

Yeah I'm planning when I get the headers and mids from MOFO to take my mids and gut the convertors and use them on Joannes QC and later get some shorty headers since it will be mainly for towing. and depending on the sound, changing the muffler.I'm like 9 seconds the exhaust is so restrictive with 4 converters its crazy, jsut getting rid of one set makes a difference. Actually when I put my tailpipes on the QC and got rid of the resonator it actually sounded better instead of the hush quiet sound it had.

And it think the pipes are 3" on the magnaflow, not sure, but I cn check if ya need me too. Thats almost embarrasing I never even paid a lick of attention untill you mentioned that, I always thought they were 3".

Most of the time your just driving the truck not needing more or all of the hp, so the tone is what I think is the best advantage to the magnaflow. The stocker is just flappy and weak imop.

I just installed a whole new exhaust system this weekend.

I put on the gibson headers and the B & B complete high flow cats and muffler system. I know that it's a bit pricy, but the sound out of this system is awesom and the quality is top notch. This truck not only now looks mean but sounds even meaner. It's got a deep throaty sound in the low RPMs and the sound of an oncoming stock car opened up.

The seat of the pant dyno says there was a definitive improvement on the bottom end through first and second gear (mine's an 05' QC auto) and a smoother climb up through the mid-range. Before the change it felt a little bit raspy like the engine was fighting to release its power. Now it feels like it can breath.

Just for anyone's info, the installer was surprised how easy the headers went in. However the gibson's do not match right up to the B & B's. Sean at ROE warned me of this ahead of time. The installer simply cut the top of the header connection on the B & B's and turned them until they lined up and re-welded them on with the MIG welder. He then used four flanges and made up two connector pieces to allow for the extra length of the QC. Took him just over 3 hours of shop time.

Now that the exhaust is done, I'm goin to install the VEC2 by the weekend. At this rate I'll be needing new tires doing my test drives. :p

9 seconds, This may be a dumb question, But I live in a state where they check emissions once a year Do you think this would be a problem with the cats removed? :(

Probably. :( Especially if you ditch both of them.
