Dynomax catback exhaust system - pseudo review
Well I got my truck last monday, put the new exhaust on Friday. The engine sounded sort of diesel/straight six-ish with the stock exhaust. The dynomax catback (dual rear outlet version, $254. from Jeggs) sounded real "tinny" and only made a "louder than stock grumble" from idle to about 1600 rpm then sounded stock from ~1800-5000rpm. I added two $12 "resonators" from walmart and now it sounds totally different, more like an indy car with a more defined idle sound to 2000rpm grumble. I also tried two of the... "rectangular outlet" tips and that gave it more of an indy car with "a bit of bark". So far I'm sticking with the resonators, just wanted to let you guys know that those tips actually make a difference in the exhaust note (enough so that I no longer want to tear it off). As for fit and finish, it takes some tweaking to get it just right and I only have about an 1/8" clearance between one of the tailpipes and shocks but I think it can be remedied by lengthing the cat to muffler pipe by about one to one and a half inches. I havent put my reese class III on yet but inital "clamp it on and see tests" reveal it should just require changing the 2 rear hangers to bolt onto the hitch instead of frame. The only real negative to it is loosing the spare tire mount (absolutely will not fit without the spare removed).
Now my question, does anyone know how the flowmaster 40 series sounds in comparison to the dynomax ultra flow? Does it give it more of a big block v-8 sound or just a louder indy car sound?

Click on the "Club FTE Member" under my avitar in the above post to goto my FTE site, then look in the top left column for the link to the .zip file. A somewhat "chopped" version of my exhaust file can also be found on exhaustsoundclips . com

It'll be my next muffler too, as soon as I can get through some unimportant stuff, like bills and food and stuff. Good grief I paid $2 a gallon for gas this morning in Portland Oregon, it cost $70 to fill up my rig, ouch !!!

single in, dual out
3" diam. pipe from OEM cat to FM40, then dual 2.25" diam. pipes out
passenger side behind tire with two 18" SS ANSA slash tips
I recorded it with the built-in microphone in my laptop, so not the best sound but it's all I got right now.
I gotta get some pix when the truck is clean. It looks pretty cool IMO.
