I am going to be replacing my exhaust and want some opinions on my setup. I still have not bought anything so i am open to suggestions!

I want to start with a set of Pacesetter Long Tube Headers, 3" Custom Y-Pipe with a Dynomax Race Bullet Muffler after the Y and a 5" Stainless Steel Exhaust Tip which will exit behind the rear passenger tire.

Has anybody here done a similar setup? What can i expect in terms of Exhaust Drone and what impact should i expect on my MPG. I currently get 14 with an even mix of city/hwy driving.

 

Im running Pacesetter LTs, no cats, X pipe, dual DMH cutouts, dual Magnaflow 4" round by 14" long mufflers and dual 4x24" tips straight back.

IDK if this helps or not.

 

Any interior exhaust drone on the highway?

 

Man Weed; your truck has to sound mean

 

How did you do your 02 sensors? I just installed pacesetter LT's with 3" y pipe to a flow master cat with 2 bungs welded behind the cat to accommodate the o2 sensors going to flow master 44 series 3" tailpipe my truck is pulling lean, rich, and high voltage codes and runs like crap. I'm pretty frustrated at this point

 

Look in our faq section as there is a thread in there on how to trick them. Along with that I stuffed them with 0000 steel wool

 

Yes, you're going to get drone with that setup, and also most other setups. Exchange that race bullet for a long dynomax super turbo and most drone will be gone. I have run that setup. Get the longest super turbo muffler you can buy or make fit

 

Maybe I'm reading this wrong, but you only talk about one cat. What happened to the other cat. and also why two bungs behind the cat. If your answer is to use the two downstream o2 sensors, you have done something completely wrong. These trucks are made to run 2 cats and 4 sensors, and if you are trying to run one cat....I can see where you're having problems. Correct me if I've assumed wrong from your post

 

^^^ good point. I didn't even read it honestly.

Most people will have two bungs before the cat. One for the OEM O2 and the other for an aftermarket wideband O2

 

It reads like this fella has headers into a y pipe out of the y pipe into one cat with two holes after the cat for o2 sensors. If that's the case. I see why his truck is running bad. Doesn't even mention an upstream o2 sensor, which doesn't really matter cause all of this is so wrong to start with. Looking at his join date, tells me he should have joined earlier and done some research
