I was thinking about getting a borla catback exhaust system, but I don't really want that rumbling sound that you typically get from installing a borla exhaust.
What does everyone else think about aftermarket exhaust?

Does it really improve gas mileage? or just a little boost in horsepower?

Is it worth getting?

 

You'll probably only get sound from a cat back on a Disco. I love the Borla on my Jeep.

 

I just stuck with stock. Borla probably will be louder but not sure.

 

Borla's tend to get very harmononic inside a Disco, I wouldn't suggest it.
THeir benefit does not support their cost. If you are looking for just a little more mellow sound, cut of your rear resinator.
There are things you can do to get your mileage up some. What have you tried so far, what octane gas are you using?

I'm using 93 octane. How do I cut my rear resinator? Is that street legal?

What do you think about K&N air filter?

What other things can you do to optimize gas mileage?

 

You can just use a sawzall and hack it off... Be sure to turn down the pipe with a tip, I have heard of D2's loosing their tail lights from the heat.

No K&N, it will kill your MAF.

Not too much for mileage on these things. Not much you can do with a 3 ton hog with the aerodynamics of a dishwasher...Look into changing your drive fluids to synthetic. It will protect better, and give you a little boost in MPG..

 

Will a "drop-in" K&N kill the MAF or the "conical" kind? What air filter works best? I was thinking about buying drop-in K&N until I saw this?

 

stay with the paper air filter. i havent heard of a problem from the use of a paper filter.

 

I think I could roast a turkey on the floor behind my drivers seat. Right underneath is the front muffler box. Good place to stick your "to go" food when you pick it up LOL! (95 D1 5spd)

 

OK, thanx for the info!
