what version of the magnaflows should i go with?

 

Are you taking the cats off? If so I think you would like what I have the Magnaflow 12468. You can't even tell it's there at highway speeds in overdrive but put it to the floor and DAMN it sounds good. Also the built in Xpipe will save you 50 bucks. I used 2.5 inch pipe all the way. There is also a bigger and smaller version of this muffler if you want quieter or louder. Also if you go with a Magnaflow you may be disapponted at first but after a couple thousand miles it gets a lot louder! They are nowhere near as annoying as slowmasters. Just don't get huge tips, they seem to add to the vibration/drone effect from my experience.

 

I think for the get go, Ill just mod the Y pipe to work with the headers then Ill save and figure my exhaust out...
I looked at Gregs pics and he has his ASMs with the factory y/cat setup untill his duals.

I think i may do that built in x, or maybe get an x with 2 seperate 2.5in/out magnaflows.... but i have no idea there

Any I will never run tips. Tips are for cars/suvs and diesels.... IMO

but some trucks look good with them.... I just dont like 'em...

I dont even have a dump on the blowmaster i have... its just straight... i may do a mini dump just to turn the fumes downward.... but may not....

 

I tried to use the stock ypipe on my ASMs but it hit the crossmember. That was cutting directly on the converter welds and welding the flange directly on the converter input. It was welded so close to the converter that I could barely squeeze the bolts in and it still hit the crossmember. I know most guys have done this with no problems though. Just a heads up in case you come across these production variances in the headers like I did.
