I'm looking for a little help. Last year I put a 440 into my Challenger, which came stock with a 318. Due to a temporary lack of funds, I had to stick with the stock exhaust (2") from the headers back (I did at least put on a set of 40 series Flowmasters). This winter I am going to put in a 2 1/2" exhaust, running the tips out the back with the box tips. My question is this: I have been told that the exhaust chokes down to 2 1/4" out the back of the mufflers, so what size tips do I get? I have seen 2" and 2 1/2", but no 2 1/4". Do these even exist? Also, what's your thoughts on chrome vs. stainless steel tips?
Thanks!
