Jeff,
Welcome to the viper family! You have lots of choices when it comes to an exhaust system. 2 years ago I made mine based upon research, sound quality and performance. Since then I have become THE spokesperson for Belangers exhaust and their largest distributor in the U.S.
The product is simply the best. The best fit, finish, sound, and I personally guarantee performance! Not to mention that our pricing is at an all time low.(see our latest summer sales info in the supplier forum of this message board)
Keep in mind that the exhaust system is the platform for ALL future mods that you may perform over the life of your car. Make a poor choice with regards to performance and you will hinder the performance all future mods and money that you may spend.
As for air filters, there is lots to choose from here as well. I have found that NO filters(only recommended for racing) nets the most power with a stock airbox. K&Ns in the stock airbox netted 3 hp over stock, no filters netted 5hp over stock. Smooth tubes are worth another 2-5 hp. Our cone filter system will net a total of 10hp and 10 ft/lbs toruqe.....again its up to you as choices are abundent from a simple filter change to a carbon fibre airbox that will set you back a G note or more.
As for break in, with 1000 miles ITS BROKE IN.
Feel free to check out some dyno results, drag strip time slips, and video clips at my website at the link below.
Every product we offer has been tested on my own Vipers.
Thanks again, welcome......and good luck with your search.
Tom
