it really depends on what kind of sound your looking for from an exhaust. I was looking at doing the same thing but decided that i preferred the sound of the magnapacks, with the magnaflow o/r x. When i looked up clips i only found one with good quality on youtube and it was the roush side exhaust which you can get on AM for around 900 i think. look up clips on here, youtube and other forums and just keep looking til you find one that your pleased with.
