How much louder is the 40 series comaped to this? I have the 80 series installed (Dual Pipes). I want the Delta's. The ones i want are the 40 series 3" Inlet and 2 1/2" Dual Outlet. How much louder is that compared to what i have right now?

 

the 40 series is going to be alot louder than the 80, it has a nice rumble to it...if i could go back i think i would get the 30 series

Rocky

 

is it alot louder all around, as far as starting it, idling, and driving?

 

I like the 40 series because at idle its not too loud, but if your behind the truck by the pipes you can hear it rumbling....then while driving at about 2500-3000 rpms it gets loud......

 

hell your in columbus, we can just meet up sometime and you can listen to mine...

 

hey man where u located? I wanna get this done tomorrow at a local exhaust shop. So there wouldnt be any way we could meet up today would there? I work until 8pm though.

 

See Im thinking the opposite of both you and Rocky...my 40 annoys me after awhile...especially at 2500-3000 rpms...it resonates in the cab some much and just drones...gets annoying fast, especially if your trying to hold a conversation or talk on the phone. Other wise its mad phat, way sic sounding at idle. Im thinking however of plopin in a magnaflow or a 50 or 80 flow. How does yours sound at idle?

 

it doesnt idle to loud. Its loud while driving but not that loud. Deffinately not as loud as the 40 but u can easily hold a conversation or whatever and u can hear the sound. Hey, if i get my 40 would u want to buy my 80 series off of me? Id sell it for 40. Only on truck for about 3 weeks. Let me know.

 

Is your cat gutted or anything? I can hold a conversation anytime while driving, cell phone or CB....

Its not THAT loud...

Rocky

 

If you want a "quieter" 40 series with little resonance, get a Delta flow 40 series.

 

whats the loud 40 series?

Will this fit on my truck? Should i trust that its an original? It says fits GM but it should fit my truck right? Good Buy??

 

with my 40 i can also have a whole conversation without it getting anoying. i can deff hear it tho and idle u can hear by the pipes kinda rumbles and gargles a lil kool sounding!! but its never got anoying before i love it!

Nick

 

the loud 40 series is the "original 40 series"

 

ok, im on the jegs website...........will this be an exact fit for my truck? Someone please let me know because i wanna get this done tomorrow. THANKS

389-430402 That is the product number. Its the same one thats on the ebay that im looking at

 

you'll need to get a centered inlet, 2.5-3.0" is OK. As long as it's those specifications, you're good..

 

That'll do!
