Time to build an exhaust, in please.
Well I decided its time to swap out the baby exhaust I have on the truck. Its an SLP 2.5" to 3" y-pipe then single in dual out muffler for split 2.5" dual rear exit with 200-cell high-flow cats.
What Im thinking of:
true dual 3" pipes all the way. 100-cell high flow cats, 4 or 5" wide cat converter case for super high flow. x-pipe. Dual dynomax vt mufflers, and a set of bullets right before the tips which will be tucked behind the rollpan.
The difference is I currenly have a baby stockish sounding cam, and will be installing the monster cam sitting in front of me, so take that into consideration.
I dont want to debate the whole catalytic converter thing, I just hate the smell of catless exhaust, and this should help keep the sound down.
Would the new set-up sound quiter than the current one?

likely no, probably louder (less restriction). but then you are also planning to run essentially 4 muflers so it should be pretty acceptable, especially exiting at the rear of the truck.
i love the smell of catless exhaust and how it gets in your clothes but that's just me. better than cologne!

Now back to the question: I would think that it'd for sure be quieter (is that a word? Lol). I had LT's into a 2.5" ory that went into 3" cat back with a si/so flowmaster 40 dumped then cut the Y off the ory and ran true dual 2.5" into (2) 3" flowmaster super 40s and it's not as loud as the first setup.
I really wanna get rid of the super 40s and go with some actual bullet mufflers

also swapping out the 87mm throttle body for a ported 90mm ls3 throttle body, didnt opt for any bigger since the TVS2300 inlet opening is a 90mm.

well, I really hate the smell of the exhaust especially since the cam is going in its gonna get pretty smelly, I mean I dont mind it but like someone just said it sticks to your clothes and you smell like a gas station.
Im not after every last horsepower here I still have ALOT to be had from boost, when I figure out how to get around the damn fuel pressure control module that is

Man that single 4" exhaust doesnt sound like the best idea for a 427 and a blower. Can it be done? For sure! Thats what boost is for it will force air through all the restrictions/bottlenecks but it doesnt sound like the most efficient setup.
I could gain much more by swapping out the pulley but i decided to do the exhaust, throttle and custom cam.
After i figure out the fuel system would be when i slap on a smaller pulley and turn it up.
Got ALOT of things to work on in the meanwhile im broke lol
