Hole in my exhaust

[Spyda]

Problem after problem!!!!!

I have a hole in my exhaust, its just after the second muffler near the join. Its fairly big and you can feel it over your hole hand when the car is running.

Im guna get the zorst place to just take off the muffler and replace it with a pipe.

What i want to know is:
How does a hole in the exhaust effect performance?
How does having less mufflers effect performance?


I have a problem that might be exhaust related. When you go full throttle the car strugles to 4k rpm and then when it gets to 4k and you are still on full throttle the reves will slowly fall untill the car backfires and/or stalls. Its all acting a bit funny latly and i havnt realy done anything to the car. I suspect its the hole in the exhaust but thats why im asking.

Hole wouldn't cause that. Dead 02 sensor or MAF might not help either. From memory your car has a cat, hotdog and two small boxes so losing one will add 1% extra power and make slightly more noise no biggie.

Most people just go one big box after the beam rather than two puny ones

The hole in the exhaust and the problem happend at about the same time, thats why i thought it could be that.

I have a BMW MAF and have had it for a while, ill replace it with the OEM one and see if that helps.

What do 02 sensors cost?

Thanks mate.

Hotdog is the term referring to a certain style of mufflers...they look like fart-cannons but they're the middle muffler replacement, not the backbox replacement

Where can i get a O2 Sensor from? Can i use one of a SEAT?

if you remove the muffler and put a bit of pipe in it sounds horrid!!!.
Carry panadol in the glovebox too!
