Q: Can i cut the cat off a run straight pipe without any problems

asked by on

Would kike to know if ill have a back pressure issue if i cut my cat off and run straight to the back

My car has 194000 miles.
My car has an automatic transmission.

It is not legal to do so unless your vehicle is for off-road use only. There should not be any issues with back pressure. Here’s a little tip, if you put in a small glass pack, or a similar muffler, it will help make the sound better and will give you a small amount of back pressure. If you loose all of the back pressure you may loose some low RPM power but gain some high rpm power.

If you’d like a second opinion on this, feel free to contact a certified mechanic who can inspect your exhaust system and help you with this modification.
