Straight Pipes

I've got a 1990 k5 4x4 silverado with a 350 and i'm thinking about putting straight pipes on it (exhaust straight from the cat... no muffler) probably 2" or 2.5" pipes, and i just wanted to know if anyone else has done this and if you've had any problems with getting pulled over for being to loud. it's not gonna be true dual exhaust... just a y-pipe right off the cat, i don't know if that matters as far as noise... i'd imagine true dual straights would be louder. do straight pipes have any affect on back pressure and low-end torque? and what size pipes should i get? i mentioned i was thinking about 2" or 2.5" because the stock exhaust is a 2.5" single pipe and i don't want to go too small so it looks good but i don't want to go too big and lower the back pressure too much. also since the exhaust is gonna be single to dual would it matter if i don't have an x pipe or an h pipe or would it even be possible or make sense to put an x or h pipe on it? thanks for any feedback.

Re: Straight Pipes

We've had our <nobr>truck</nobr> for a few days now and havent gotten pulled over yet. its got straight dual pipes, no cats or mufflers, and cherrybombs, so trust me, you'll be fine. just dont hammer on it in front of the cops. [img]images/graemlins/RockOn.gif[/img]

Oh yeah, and the thing is frickin loud... had another chevy a couple years back with a gibson cat-back exhaust.... this thing is sooo much louder...
