Cheap exhaust mods?

apoto11 · 08-04-2008, 09:08 PM

Hey guys I was wondering if anybody knows of any cheap/free exhaust mods that will change the sound of the exhaust. I'm not expecting to gain anything performance wise just something cheap that would sound cool.

If anyone knows of anything thanks in advance,

Aaron

you can always remove/gut the cat. Not sure what it would sound like on the 4.0, but it made my dad's 5.0 F-150 sound much better with 40 series Flows when we took off one of the cats. Or you could straight pipe or go with a glasspack. Or cut outs. Not sure how any of these would sounds, but they would make it louder. the only way to make it sound BETTER is a quality aftermarket muffler/cat-back

No, you can't remove or gut the cat, as it is against the law. This has been covered all over this forum.

As for a legal and cheap solution...just get a glasspack. They're wicked cheap and pretty sturdy so you won't need to replace it after smashing it on a rock.

Glasspacks are like $20-30 at any auto store.

I got a 30 dollar glass pack from kragen and it sounds bad a$$. I used another piece of angle tube to make the exhaust hit the ground instead of the rear axle. It sounds good looks good and the performance differance is incredible

go offroading in the pits by your house, then when your friend says there's no way you can do that when you come to a rocky part, land really really hard on that 5th rock down there on the right and just take the tail pipe right off...smash up the muffler real good too and cause yourself a $200 repair job...but it'll sound cool till you need to get it fixed for inspection

I like this idea the most

ROFL hey its custom and free as far as exhaust.

Since there is no inspection in Oregon is it legal to remove the cat? Or is it a Fed thing? My cat is rattling real bad and I don't feel anything loose with the shields so I am thinking it is the guts. I was thinking about just putting a test pipe in its place but I think that may also cause the check engine light to stay on?

Thanks

my fiance's cat is rattling in her audi and its because the innards are shot. u can get a replacement cat on the internet for like $40. i just got her a magnaflow replacement high flow cat for $40

check it out.

Removing the cat and gutting/replacing it with a test pipe will make the truck louder. As for legality... if the state of Oregon doesn't perform a safety and smog check via state inspection, then I say do whatever you feel comfortable with.

You can gut the cat and the majority of places wont notice or really care. I wouldn't recommend taking it off because in an inspection they usually will take a peak underneath your Jeep to check for rot and things like that. As far as the cherrybomb/glasspack idea, my friend put one on his YJ, made it louder but pretty raspy and crappy sounding in my opinion. Sounds alright at low rpms. You'll be a lot happier in the long run with a nice flowmaster 40 series so save up and do it the right way.

I had this idea, it might be horrible but why not take a cat, gut it out, and use the shell around a straight pipe so you pass inspections, can just cut it at the top and reweld it where no one will see it if need be

Hmm illegal, fails smog tests, sound will be a dead giveaway and otherwise a rather stupid idea. Oh yeah, without backpressure your performance will get worse.

It is a federal law you are going to break taking off the cat. No smog test makes it less likely you get caught but still illegal.
