Performance Exhaust System

Apparently on diesels the Cat or Cats does most silencing. Also being turbo charged it does not need back pressure as this is created by the turbo and tuned to match this. I am amazed of the sound of the straight six diesel and think it was a good mod for the money. I was not after added performance as if i wanted more power i would get it chipped. Waiting for the snow to lay off so can get the sponge out give it a wash and post some pics.

oh, interesting. ya i don't know much about diesel. i was referring to gasoline vehicles.



and everyone tomorrow the magnaflows get put on!! hopefully it turns out well in sound and performance.

looking forward to seeing it on man =)

Yes that sounds like is a logical explanation, I might go switch to an X pipe and see what happens...will probably sound completely different. How would the straight pipes benefit the V8, in this case each bank would have a separate exhaust? Good luck with your set up!!

I would also be interested in pics and sound clip as I am considering custom mufflers too...

I was thinking if my setup works out, since he has all the measurements, (not sure if the V8 is the same as the 3.0), but if it is, he can make more systems. I'm sure he'll cut a deal for members.

I can weld the mufflers in myself, and if I don't have time (as I didn't last time) I have an exhaust shop friend that hooks me up! More of just hearing different setups to make the decisions.

And yes, the 3.0i and V8 have the same measurements, at least for placement, for the rear part fo the exhaust. (flanges back)

Alright guys the magnaflows are on! it sounds WAAY better than anticipated. I highly recommend it. I think it might blow away the supersprint system haha. I have some pictures for now, whats the best way to get the videos up here? Im thinking youtube, but any other options?








So there definately is some kind of performance gain. Sounds great (i have the clips just need to get them up). My only complaint is the positioning of the tips. I feel like they are sticking out too much, and the right one is a little sideways. im going to have to get that fixed..

im glad that the magnaflow did wonders. you can probably host through youtube or just plain photobucket if you're uploading pics from there as well. can i see a back shot of the X ? the tips seem to stick about a bit more or is it just me? and btw how much did the exhaust cost you

I guess it's much louder than the x-pipe and stock mufflers. I'm really curious how it sounds!
