well if you dont ever plan on upgrading your turbo on the spyder, 2.5" will work fine for the t-25. but if you have plans for your car i would go with 3". it can flow any cfm turbo you put on the car. check out www.vfaq.com for some do it yourself help on building a car. or go to www.roadraceengineering.com or www.buschurracing.com. both sell exhausts for our cars. hope that helps.

i would go with 3in.. you dont need the back pressure a n/t does so 3 would be fine.

yea 3' is the best.. also you might want to port the elbo also to free up as much back pressure as possible..
