just installed my true 5" turbo back "free flow" pipe. @ 1500 rpm's there's a good drone. not that big a deal but would a bigger tip help this. thanks for the info

 

whered you find that at?

 

hey bud, shopdiesel.com. 300$ 5" downpipe and all the way back . sounds like a CAT.

 

Had the same drone on my '97 with a 5" system...
Made me put my stacks back on

4" straight pipe on my '05, left the kitty intact, no drone at cruise, ONLY slight drone is convertor locking up...

 

thanks did u have a tip on it or would that not make a difference

 

On the 5" system, it went all the way out, past the rear tire, pipe that was in the kit....

It was a 4" downpipe, and 5" all the way back...
Lost some spool time too, felt a little more lag...


That was just my experience with the 5" systems...

Keeping the 4" on my '05 for a while, it flows well enough and sounds decent...

Might help to try a dynomax bullet, or like, straight thru muffler to eliminate some of the drone...
Otherwise, stock up on sound deadner
<- had lead plate from Xray rooms as sound deadner, and no I didnt do it, was on the truck when I bought it, but it actually works pretty well

 

yeah i cant tell if theres a lag or not. it seems like since i put it on the clutch slips more. i think that its because it ads power. mines 5" downpipe also

 

Stock turbo?

 

I get a slight drone right at 1500rpm with my stock 4" exhaust with muffler removed via MEK from Geno's. It is more noticable while towing. Not too bad unloaded.

 

I have some good droan in my truck 55mph@1500rpms when the truck is going into overdrive. All I have is a 4" straight pipe with everything removed.

Doesn't really bother me unless I'm at 55mph on traffic.
