How much power would I gain from adding a set of pacesetter long tubes to my 98 gt with pi swap ? Bet it would sound awesome

Lol I'll deal with it I plan on doing cam swap end of year as well so sure smog will be an issue regardless, which cam will work with pi swap ?

wont gain much till you add cams to your motor, but it'll straight out your power curve. theres a good write up about this on moddedmustangs

I heard I would gain anywhere above 12-20whp maybe that's with a tune I've seen dyno sheets with pi swap and long tubes making nearly 280whp.. and over 300 whp with cams

if you want 300whp pi swap the write up on modularheashop.com also has dyno results i believe also LT are part of making it to 300 there without fi or spray
Have you done the rest of the tb/plenum and pulleys?i know youve done pi swap and gears.
As far as cams i you can do trickflow stage ones with out any issues.

Summitracing has them. With stock pi heads and 4.10s I was hitting 12.8 on motor but could have hit 12.7 or 12.6 but I didn't run on motor to many times at the track and the 12.8 was with a 1.9 or 1.8 60ft only.
