The performance gains from a CAT-back are small anyway. Get whatever suits your tastes and your wallet.

The stock size is 1 7/8". This is a quote from the magnaflow website: "It is better to use a smaller diameter mandrel bent pipe than a larger crush bent pipe. Remember that maintaining velocity is just as important as reducing backpressure.
PIPE DIAMETER GUIDELINES
Some basic exhaust pipe diameter guidelines for non-turbo cars are as follows:
1,500cc-2,000cc engines : 2-inch
2,100cc-2,500cc engines : 2.25-inch
2,600cc-3,000cc engines : 2.5-inch"

Hey Buggy, I responded last time you posted about an inexpensive Cat-back saying spend the dough for something like the YoDude in 2 1/4. Then some jetters were posting about all this and Naz said his HKS is small pipe and it's one of the pricey ones. So after checking around some more, I've changed my mind. Also, as stated before the gains aren't that big to start with, 6hp to maybe 8hp. So maybe you get a less efficient one and only get 4hp to 6hp, not much of a difference. So get what you like.
I installed the Flowmaster system this morning, very eazy.I was using a Borla up until now. The Flowmaster is working like I thought it would. Its alot quieter than the Borla and still has a nice burble. Its has a low note at idle like the borla.Its really quiet inside and while driving freeway speeds only slightly louder than stock. The fit was perfect. The tip is a little smaller than the Borla. Power feels good through the entire RPM range. Low end is strong and better than the Borla. Im keeping the Flowmaster and selling the Borla.
I am selling the Borla. It has a resonator added to the front section so it is a bit quieter. It has 3000 mi on it and looks like new. Im going to try and sell it locally at first.Anyone living in the Rosegurg/ Eugene Oregon area can have it installed in my shop, no charge. I want to get $300 for it.
