What do you think?

Hey all, this is my first post with a quick question about my first diesel. 3 days ago I picked a 1996 7.3L Ext. Cab LB I figured the best thing to start with was a new exhaust system. After a little research I came up with this

MBRP Performance Exhaust

I was wondering if any of you have had experience with this kit and/or if you had any other suggestions.

Add the 6637 air breather mod and you're good to go. Beyond that you'll hear the sound of the vacuum that's sucking the $$$ from your wallet. Tunes are the next stage.

I put that kit on my CCSB, it was very simple.

Dont forget, you will have to make room by the transmission for the downpipe to get through.

So basically the mod is to get the 6637 filter and to run it without an airbox? Sorry Im a diesel noob.

Thanks for your imput man. I couldn't find the specs of that particular kit on their website but I believe the down pipe is 3" and the rest is 4"? Wont a 3" down pipe fit without any modding? I know the stock down pipe is squashed flat but it looks like theres some room. Thanks for your help

thats the idea. some guys build an airbox, totaly up to you. i didnt.

yes 3" DP then 4" back. you will have to cut the flap DP out, and will likely have to cut or pound out a portion of the firewall to make it fit. most/all of us do.

Isn't it dangerous having the DP right up against the firewall?

Is it possible to find the exhaust system that I linked to for cheaper than it is on MBRP's site?

[ridiculously_necessary]

no, its fine. just might have a bit more heat bleed. none of us have had any problems. (that i know of) its the most popular mod to these trucks. that flat DP has to go, im sure the engineer that did that thought it was funny.

check with Raul her eon the org. or Cary at CT_performance, they are both site sponsors.

Ok thanks for the help man. Another question about the air filter, it seems like if I took the air box out the engine would be sucking a lot of hot air from the engine compartment? Is this just something that you have to deal with to get increased airflow? At the moment from what iv heard im kinda leaning toward just buying a kit from banks.
