personally I like 3" over 2 1/2". the bigger tubes are not as raspy and usually are a much deepper tone as well.

I have not used the Magnaflow 3" on a mini tub yet. But it looks like it would fit. We have been selling and using Magnaflow quite a bit lately. I really like the sound. The 57 we just finished has it and I love it. I would go 3" if the car is making 500 or more ponies.

Why 500 or more H.P'S? ( not being a S/A just wondering why 500) I have a ZZ4 (355 H.P) in my Nova and am switching from Flowmasters to Magnaflows,was thinking about going to 3 but I seen your reply and was curious.Thanks.

The reason Frank suggests 3" for 500+hp, is to prevent a hp loss due to a restrictive exhaust flow. Ive seen as much as a 20hp loss when 2.5 inch system is used on a 500+hp mill. Especially on crimp bent pipes. With the hp you mention a nice mandrel bent 2.5" system should be more than adiquite.

I just bought a set of Magnaflow 3" for my pro street and look forward to hearing them jingle!
Main reason i bought them is there fitment for my set up im running fenderwell headers and they will be on the outside of my frame rails tuck up under the car, mated to a 406 215 cc Dart alumin heads 6" rods and a single pnae 750
Hows those bullets sound on your ride? look good
