What size would be best for a true dual system on a car with very few mods planned? I have read that 2 1/4" will keep my torque in the low and mid rpm range, while a 2 1/2" will push it up in the powerband.

My planned mods are head work, maf, tb, and chip. I figure about 260-270 hp at the crank. I am looking for mainly street performance (daily driver). Just a few trips to the track here and there.

Thanks in advance for the advice! :)

the shop is mos likely going to use compression bending, so i'd go with 2.5 dual or 3 single.

Kewl. Thanks for the info. That's what I was thinking, too. 2.5" all the way back. Hopefully, I won't lose too much torque. Future mods are coming, but for now, I still gotta drive my baby!! :D

Not sure what kind of setup the 90 sc's have as far as gas tank but a good exhaust shop should be able to hook you up with what you want.
