I'm sure you will be fine, let us know how everything goes...
I'm still undecided on what I'm going to do. I haven't been this stressed in awhile trying to decide which headers to go with... I currently have the RandomTech High-Flow Cats which I was told has a 300-400 cell count. I have no idea what the Belanger Cats are, but I was told the Roe Racing's cats are 200 cell count and from American Racing's website, theirs are also a 200 cell count. If I decide to get the American Racing headers, I will most likely purchase their high-flow cats to go along with the headers since they have a lower cell count. If I get the Belanger Headers, I will probably end up keeping my RandomTech Cats unless the Belanger Cats happen to be a lower Cell Count.
I was just told the lower the cell count, the better performance and the louder the sound. In my book that's worth switching to another Cat. Unless the difference is extremely subtle, I'll just save my money and keep the RT Cats I currently have.
I was also told that these Header companies don't produce their own cats anyway, so they could be getting them from anyone. However RandomTech is a well known American brand so you know what you're getting. I just really want the lower Cell Count, if it infact matters
I have also read that the 100 cell count may smell more like cat-less. I want a little cleaning of the smell/fumes and most performance possible. I had random tech previously on the car but a fouled O2 sensor messed it up. Check your O2 sensors!! I originally wanted bassani cats, they look well made, but I could not find them for sale anywhere.
I e-mailed the two shops to see what was going on with my order. Hope they don't **** me around, that is real annoying. Good luck with your Viper!
