Exhaust Hissing

turbo_beast369 · Postby **turbo_beast369** » May 24th, 2010, 4:01 pm

Car is a stock CS3 lancer with a 4G18

I had a stock exhaust system and was hearin a slight hissing sound (kinda like a rattle snake) whenever i drive by a wall or another car and even when i am driving normally...i thought it was the cat converter so i replaced with a resonator/silencer ting dem muffler shop does have...but i am still getting the noise...went by 3 muffler shops but they not seein any leaks..the ring gasket at the end of the exhaust manifold was changed as well (OEM)

could it be possible that my down pipe from my manifold has gotten thin on the inside due to age/heat and it kinda echoeing in the chamber?

I have asked guys with same car/engine who have taken out their cat cons and they not gettin d noise I am getting...

I am no exhaust pro, but did you also check out the exhaust manifold gasket coming off the head?

What exhaust shops you went to exactly?

exhaust manifold gasket coming off the head is good...

I went by Imraj, Mickey and a guy name Mazda (in a street off of cipero st that connects to todd street)

Mazda fella would be on Westwood street I think, at the bottom of the hill..

Interestingly I dealt with all 3 of those exhaust men in the past.. All have done good jobs really

nah d car still sounds like it has an exhaust leak

I feel is because the catalytic converter was taken out...even tho it was replaced with a silencer it still sounds like it leakin....I fedup tryin to figure it out...I wanna change d engine next year so i wont hurt meh head too much...

Was asking cause I'm having the same problem I took out my stock manifold and replaced it with an extractor kit...The cat-convert was taken out, the old barrel was replaced with a fujitsubo barrel that came off an S14 and there's a resonator.

I was told to go check a guy not too far from Roopnarines on the Caroni Savannah road to try and sort it out.

It would be nice to go to a good muffler shop that would have someone who just don't install muffler systems but can give you good advice based upon what you want....

Go check 2001 specialist on Manahambre Rd, St. Madeline...
He is rather knowledgeable and is a step above your average welder/installer!

are you running aftermarket barrel? Most of the cheapo ones are sheit and will make noise when the inner insulation burns away.

I was gettin the noise since even b4 I installed my aftermarket exhaust....its the same b4 and after...and I don't have a cheapo barrel...its a Fujitsubo exhaust
