dump pipe leak affect performance?

[JH32]

I just fitted a one piece dump and front pipe to my car, tho I couldn't do one of the bolts up tight enough. So I have all bolts except one done up tight.

I'm not sure if there's a leak, but if there is will it affect performance?

Someone told me it won't, as it's after the turbo, but is this true?

I dont think it will affect performance in the short term, but it will most likely make the gasket more prone to failure, then you will have an annoying exhaust leak that will make the car sound terrible.

if the fumes get into the cabin you could die as well

probably not recommended for there to be leaks .. i mean i got one in my exhaust somewhere and i'm too lazy to do anything about it .. but what happens is that i rev up just fine .. no problems there .. but when u let go it doesn't go down smoothly which i guess i dont' just like .. theres a small splutter sound ... doesn't sound too nice to me ... and the rev needle bounces up and down slightly ... so yeah i'd make sure theres no leaks ...

you get interesting sounds..

Would it effect the 02 sensor since its not getting all the air?

[sweetr33]

no. O2 sensor wont be affect. Leak wouldnt be helping your exhuast system hold back pressure. Theres no advantages in having the POSSIBLE leak there so i would try n tighten that bolt up and if its in a pig of a place then get some bendy bits n pieces for your ratchet or what have u.

its skeletor

Yeah I had the same trouble, one bolt very had to get to, if you do the other ones up as tight as possible and the hard one fairly tight it shouldn't leak, get someone to heat up a spanner with an oxy and give it a bend, it helps.

Cheers guys for the help

I might end up having to take it to somewhere to get done as I don't really have the time to do it myself, but I think i definitely should get it looked at.

how bad is yours leaking? can you hear it? or feel the air leaking out when u put your hand next to it while the motor's running? mine was that bad and sounded like a truck (sr20)
