Walker Big Truck Muffler

Well my wife wouldn't approve a full exhaust so I bought a Walker BTM and WOW. It sounds awesome. I didn't want to straight pipe it because of my VERY old neightbors. So now with that muffler and no cat, my EGT's should be alot lower. I'll have to get some pics together.

Thanks for the info. I just bought a magnaflow muffler to replace my stock muffler. I too am hoping for some lower EGT's.

Ever since I did this I see more smoke. I just can't see how putting on a high flow muffler will make it smoke more. I didn't change any tune or anything else. Hmm

The cat catches a lot of the smoke. Given the high temps in the cat the excessive fuel is burnt.

I will agree with the cat catching the smoke. I know I just did a 4in straight pipe from the turbo back on my 04' and it does smoke just a little on start up but what I notice the most is that it smells alot more like a diesel should now. Maybe that also has something to do with the EGR by-pass (done the same time as exhaust) but I notice it smells aswsome. Gets me going in the moring when I start it from inside the house and I come out 3-5min later and walk around and get that smell. Just gets my blood going in the AM... It is louder though my 04 stock turbo sounds like an industiral hair drier and the whine is great bouncing off the walls of my old neighbors...haha
