i was driving home yesterday and i noticed my exhaust was sounding weird.ive already replaced the pistons and its on the factory tune. so it shouldnt of popped another piston. compression is fine. im running out of things to check


i have the ss/sc dp and pacesetter exhaust. i thought it may have been my exhaust leak but i fixed that and the sound is louder

is it missfiring?

madmark

no it runs good. no miss/ hard start as far as i know its just a new sound

souds to me like its not fitting flush with the header gasket to the head..

its not a leak, its comming out the back of the exhaust

Many of the LSJ guys speak of WRX sound and it's usually a massive engine problem.

i think it may be my cat that is screwed up, im going to go get it removed and see if it still does it

Did you ever find out the cause of your problem. I started a thread about this on my car. The first time I had a bad coil pack and it sounded just like a WRX while it was on 2 cylinders. Now, it has this less noticeable WRX sound and nobody can tell me what's the cause of it. It's not the cat or resonator. I was wondering if it could be the gasket b/n the head and exhaust manifold.

well i decided against cutting out the cat.... i have a feeling my car needs to be tuned, i am smelling fuel from the exhaust. there is no missfires so my coils are fine

red06s/c

SS/SCking

Ya mine sounds like a wrx and its not a good sound to have. You can see in my sig what caused the wrx sound(#4 & prob#2gone)

yep, im a tech and im confused all to hell =\..... since trifecta is the only tuning sourse for the l61 i have to wait to see if that is it

copson20
