No problem, glad I could help. I actually have one of those 12588's myself, sitting in my garage, ready to weld in. I have to get rid of the Flowmaster, not because I don't like the sound (it's amazing, it's perfect), but because they don't flow worth a crap and I need to get the air out with the blower.

I also have a 12249 going right in front of the 12588, cuz I like it quiet.

Up at Hot August Nights, DynoMax and a big display setup with most exhaust manufactures hooked up to a flow meter (except magnaflow). So hit the button and flow activated. Damn flowmaster came in dead last with the worst flow! The muffler that was hooked up just happend to be the one i have installed in my truck, the flowmaster part # 530552. So this is where i need your help...

Currenly i have a flowmaster 530552 3" in /dual 2.5" out SUV 3 chamber muffler on my truck measures 5"x10"x17" overall length 23". Dual 2.5" pipes leading out the back of the truck on either side of the hitch. This system was custom installed by my local muffler shop. I would like a replacement Magnaflow muffler for my truck for better flow. Im running a blower so choosing the right magnaflow muffler with the best flow is important. While visiting magnaflows web site their are so many mufflers to choose from. Round body, oval body, XL 3 chamber. Which is better? Sorry for the long post, but i want to make the right choice. Oh and i PM'ed oxidizer for a responce but i got nothing im sure he works for magnaflow, mabey he's just too busy.
How was the show up in danville?
The next one is on the 25th, right?

I just listen to Randy's (litreddevil) and it's exactly what i was looking for. It's the 6"x18" round 3"in/3" out Magnaflow #12649. It has a deep tone and pretty quiet. He didn't have the tail pipe on yet so it should sound better when he installs it. Thanks Randy for taking the time.

I need quit. Something about going on a long trip with the camper and having the old lady making more noise the the exhaust because it's to loud. But there's allways the cutout for the track

An Avalanche guy who owns 5 exhaust shops in Oregon told me that the 12588 was the quietest aftermarket muffler out.

So this should be equal to the 12588 just single in and out
