Got that sucker installed this morning, The deep sound it puts out is AWESOME!!!! its not as loud as i expected but then again i been listening to straight pipes for the past 6 months... BUT i also bought that 26 buck Y pipe from magnaflow and they said it was junk and i am better off just getting the whole thing.. Wat you guys think? If i do get the whole y pipe instead of like that adapter i bought i want to run new pipes all the way threw, wat would be the best size? and for headers, which is the best for a 4.7? and adding larger pipes for the exhaust will that make it louder? thanks guys!!! love the CB extreme SI DO, highly recommend it!

 

let it break in for a couple thousand miles, then you will really hear how loud it is. and i dunno what that guy was talking about with the y pipe. sounds like you need a new exhaust guy.

 

I just got in from the exhaust shop. Now I have the 5.7 but what I did was have them cut the stock pipes right at the factory cats, they ran 2.5" stainless pipe like how the factory y was routed then isntead of going into a y, it stays dual pipes which a "H" crossover and runs into a dual inlet single outlet magnaflow muffler. I wanted to get rid of that crappy factory y pipe. Now I know your running a single in muffler dual out. So maybe have them run 2.5" Pipes from the cats, under the transpan etc into a "y" pipe custom made then into 3" pipes back to you muffler??

It seems many guys jut get the magnaflow y piece and get it welded in, but I wanted to get rid of that crazy crushed piece that runs under the trans pan

 

So the cherrybombs will get louder as they go? i heard some mufflers did that but did not know about the CB EX would

 

Yea the stock y on my 4.7L is pinched big time when i was lookin at it, i am just going to take it to my buddies shop and me and him cut the pipes and run new pipes into the y pipe i got and weld it all together, i should have done my exhaust that way, but they only charged me 25 bucks for install

 

pretty much all mufflers will change sound as they break in. my AT3030 started out fairly mellow, but now it SCREAMS

 

Dunno, sounds like that guy just didn't want to do the Y pipe, it takes a little fabbin' unlike the muffler.

I know the two performance shops (not muffler shops) where I talk to people RAVE that Maggie "Y"...

 

See i know how i am going to do it, and i even told them that and the owner of the shop said they use those y pipes for the split into duals out the back, they really aint a y pipe....... i just got my y pipe and left, but about me running new pipe all the way back? for a 4.7 would a 3in be to big?

 

yes i have to agree with ODJ , when i installed my CB extream it was low and mean, now after a few 10 miles its getting louder and i like it .

 

I'd be very curious to know what their definition of a "Y" pipe is...
