These are simply guestimates, no real hard data to back them up, but this is probably pretty accurate. The full catback will net a bit of a deeper sound due to slightly larger tubing and lack of kinks in the tubing.
It'd be cool if the FRPP was a worthy setup, but the aftermarket is just filled with quality setups. FRPP makes a SS side exhaust catback kit for the Gen 2 SN95, but the MSRP is (gulp) $950.00! That deserves the flag-->spikeGT_99 said:while im asking about exhaust, does the ford racing exhaust for the 99+ gts make any power or sound any different??? just think itd be cool to keep as much ford racing stuff on there as possible

Your estimate is much closer. A Dynomax 2.5" cat-back with Ultraflows dyno tested +4.2 rwhp. This test used to be posted on seanhylandmotorsports.com.Kyle-02GT said:I think you might be a bit high on your estimates probably closer to half that on just the catback more or less depending on type. You make more power the closer to the engine you get but things also get more expensive Catback < O/R MidPipe < LongTubes.
