3 inch downpipe install.

[96OBS]

Hey guys i had a 4 inch exhaust put from stock downpipe back because the muffler shop couldn't do it. Well I was just gonna take it to a shop and have it done but I figured I could save about a hundred by doing it myself. On a scale from 1-10 how hard is it. I'm 16 and was gonna have my dad help me and just get a 4 to 3 inch reducer or flex pipe and clamp them together. What tools do I need to complete the job? The only thing I was worried about is the firewall.

you have to massage the firewall to get it to fit

Hard to say since everyones view on whats hard and not hard to do is different, Honestly its fairly easy and can be done in a few hrs.

I'm guessing massage means beat the crap out of it?

Not always, some trucks need it more then others.

Okay cool well I guess I'll go ahead and order the mbrp and do it when it gets here, also gotta do a fuel bowl reseal kit so I'll make a work day.

Easiest way to go is use a porta power for the firewall, if you don't have one usually you can rent one from a local auto parts store.

like said a porta power with a duck bill works best, or a hammer and peie of wood to get the desired room, then take a metal baseball bat and use the end to round off any points, just a lil extra for a cleaner look then all beaten in is all.... not hard to do at all. tok me an hr and a few beers. lol

Baseball bag is one of the best things to use with doing a downpipe install

You may also just get lucky, mine went in without any massaging at all.

Mine just a little prying with a long pry bar. Getting the 3 inch pipe in is easy. Its getting a stock pancake out thats a pain.

Sweet, after I find my stupid fuel leak I'm gonna do it..
