im trying to figure out how to make 11's on motor. im coming up with a ported fast 90/90 and true duel 3" exhaust. i dont want to lose my low end though. i was thinking about going to the track and unbolting everything right at the headers and seeing how it acts. that would be LOUD hahaha.

 

I wouldn't say that you NEED it... but I'm sure your top end will see a gain.

BTW, why is this in the Dodge exhaust section?

 

not sure why its in dodge haha. i just saw exhaust and clicked it. you can move it if you want.

ok so i will gain up top but will my bottom end change any? im plannin the fast 90/90 some day (not soon)

 

There is a chart around here that shows pipe size/hp relationship for single and dual exhasut. iirc dual 3" was good for ~500-600hp


oh, and I moved this for ya

 

I dont think it'll be a gain right now? but thats just me,,, i f you 60's were alot better I would then, cause it would really suck to loose some bottom end?

 

Well, what exhaust setup are you running now?
And, btw... it would soooooo loud. Here is my 2.5'' duals.

 

right now its pacesetters, the old style pacesetter ory into a 18" bullet into corsa dumped. the old style corsa Y pipe looks like it would flow like crap.

 

heres my 3in duals i made..it has a corsa xpipe, some bullet style mufflers i made, with some turn downs that have some cone mufflers inserts i welded inside of them..if i were you, id do it anyways..even if you dont need it now you will need it sooner or later..when i went from 2.5 duals to 3 in duals the upper end felt alot better

 

i'd say a 3" y pipe setup and just run a 3" cutout before the muffler.

 

IMO 3in before Y the 3.5 after...
