Yo Nadz, great idea...I'm looking into the same thing with my new KR.
sig, just wondering WHY you recommend true duals.
From reading a lot of posts on three different forums, I had just about had it narrowed down to the FlowMaster Super 40. However, I just visited a local truck accessories store that sells them all, and asked the owner which they sell the most of, the FlowMaster or the MagnaFlow. He said he sells more of the Vortex Cherry Bombs than everything else put together...totally surprised me. Anybody know anything about them? I've never seen them mentioned in any of the forums. But, this guy sure sounded like he knew what he was talking about.
And, he said they have a computerized pipe bender that they just plug in the vehicle year and type and it will bend it to specifications. He also said it's way cheaper with any of them to just buy your muffler, or mufflers, and extensions...then let the shop bend the pipe to fit, instead of buying the entire FlowMaster, or MagaFlow, or whatever, kit. (as sig mentioned above) I didn't get a quote on the rest, but the Vortex Cherry Bomb he quoted me for everything installed at $225.
Here's the link to the website.
And, like I said, I have no idea...but this does give me something else to consider. He said I could come back anytime and listen to the difference.
