does anyone make these for our trucks? i was looking to do dual cat backs on my truck, but i only see they have them for 94 and up could i buy a 94 kit and modify it to fit my truck? or is to much modifying? do any of you know of a company who makes this kit for these trucks? anyone have pics of there set up?

 

our 1st gens dont have cataletic converters but you could probably run it strait back to the y

 

yeah thats what i was thinking, if i could delete the cat and muffler and just get the y pipe, then i can make it work possibly.

 

With the way the shocks are mounted on a 1st gen, I doubt a 2nd gen dual kit would fit. It might though.

IMO duals don't sound the best on a Cummins.

 

I have dual 3" on my dodge that Brunelle Tire Factory bent for me for $300 and it sounds great, i'm going to hopefully be adding a 5" downpipe and running 5" all the way to the duals. After buying the materials and fabbing the pipe i think my entire system will be about $450 which i don't think is to bad...

 

woohh, did you just get all staright pipe? and get them to bend it to fit? or howd u go about doin this custom job? also couldent i relocate the shocks, i do have a welder and the skill to be able to make new shock mounts. or relocate them if need be

 

90ctd- if you go have dual 3s now, you will be choking a single 5". You must figure the cross sectional area of the pipe, not diameter. So, pi(r-squared) gives us:

DUAL 3"- (3.14 x 1.5 x 1.5) x 2= 14.13sq in total area.

SINGLE 5- (3.14x 2.5x2.5) = 19.625 sq in total area. Going from 5" to dual 3s gives you a 28% reduction in total area.

My thinking on dual exhaust is- it's fine for V8s with no turbo. When you stuff it all through a turbo, with one outlet, you defeat the purpose of duals. Going with a bigger single is easier. I havent seen too many dual exhaust systems that were even several years later- one alwys leans to one side or another.
