Thanks, Guys. I appreciate your advice.
I did order the K&N FIPK.
I looked at Flowmaster's web site, they do not have a 70 series big block exhaust for me - my system has 2 separate cats on 3 inch pipes.
The muffler has dual 3 inch pipes come in and out.
After that they have a Y to get from 2 to 1 pipe, still at 3 inches.
My muffler is 9" high, 12" wide, 24" long.
This is similar to the flowmaster dimensions.
Could this be a 'free enough' flowing muffler?
It does sound pretty hollow and roomy.
I did look at Western's web site, and their chip programming is very customized and detailed.
I do not want to pull/replace my chip, so I may go with the Hypertech programmer that connects to the diags port.
It costs 1/2 the price, and I hope that it is good enough.
They do show some encouraging Dyno pics.
Thanks again for your advice.
Please post any thoughts on this.
Take care, Eggert
