exhaust problem please help

Muffler delete? Exhaust systems may not legally be modified in that manner.

note: "car running is legal" in my country and my question was about the harm on the engine ?

i ment car tuning not running

Car tuning is legal here, too. You'd be better off buying something like a Borla, MagnaFlow, or FlowMaster cat-back system.

You;re looking for a delicate balance when it comes to backpressure in the exhaust. Too little, and you damage the engine in relatively short time. Too much, and you damage the engine even quicker.

Thnx for the advise
But buying borla catback or magna fl

Thnx for the advise.
But buying some borlas or magna flows are expensive I'm not willing to pay that much
I have bought magna flow exhaust tips so I can weld them with the pipes so should I do it ?

Weld the tips on, no problem. If you can replace the stock mufflers with glasspacks, I would.

You can just take the resanators which are in the back of the car the muffler is in the center of the exshaust. I see it all the time at my work sounds good and its easy

I want to remoe the muffler that's in the rear Of the car and weld the tips on a straight pipe is it good or bad this is my question ?

Those aren't the mufflers they are resanators but yes you can

I want to cut off the mufflers that are in the very back of the car and replace with a pipe and weld stainless steel tips is it good or bad for my car or my engine ?
And what do you recommend to me for Making my car louder without damaging the engine ?
Thank you .

Yeah just the pipes will be fine and it won't do anything the the engine still has enough back pressure with the cats on it still

Thank you that was helpful .
I have another question :
Can I remove both mufflers the one in the middle and the ones in the back and replace them with stainless pipes and welded to tips woul it effect the back pressure or the engine ?

Yeah it will be fine as long ad you keep the cats on
