Compared to other catbacks, why is the flowmaster less. I like the force II system because it is not as loud, but the price is so low it makes me question quality/performance.
2009 - 2010 Dodge Challenger RT 5.7L V-8 Stainless Steel FII  - $797.60 : Flowmaster Inc. Exhaust Shop, Love That Sound!Yeah i dont think they are stainless.
You are my kind of customer. Can I interest you in a $3K exhaust system?Somethings not right about it. U get what u pay for.
Non mandrel bending is called "crush bending", around here anyway. If it's "crushed" you can easily tell because the diameter of the tubing is reduced where it's bent, and mandrel bent tubing stays the same through the bend. I had an exhaust made for my truck years ago while I watched and it was the first time I saw mandrel bending. It sounded great, but sadly I hit a tree stump and I had to hacksaw it off after it got all crushed up around the rear axle. I ended up having a replacement made from mandrel bent prebent pieces of tubing and 3" turbo mufflers. It was LOUD. Full throttle runs were amazing, it sounded so great, but I got warned about the noise several times my cops over the 3 years I had it on. Most of them agreed it sounded like it had 600 HP, and they liked it. I would guess if I was lucky, it had maybe 400 in reality. It was a 360, with ported heads and bigger valves, ported intake, worked over Thermoquad carb (A good TQ beats an equivilant Holley, easily) a moderate cam, headers and the above exhaust. Very short and not much restriction or sound control, at all. If I could get my Challenger to sound like the truck, but maybe half as loud, it would be perfect. My mother used to say that she could hear me turn into her street about a half mile down from her house. I don't really doubt it. I don't want the Challenger that loud.The "mandrel bent" thing is odd to me. How is pipe bent if it isn't mandrel bent? And is this other technique (whatever it is) really all that inferior? I have to imagine that however it's bent the people doing it would take care to do it in such a way as to not impede flow to any significant degree. Am I right or is the "mandrel bent" feature that all the aftermarket companies brag about the only way to go?
