Hi guys so i finally got my car back (bout time too)

had a custom exhaust made from the headers (which are ceramic coated thats why they shiny not sure if i should just have the rest of the exhaust done?) all the way to the exhaust tips which i kept standard.

I have one concern though.................it smells like petrol


After a good run there is this unmistakable smell of petrol comes through, once you redo the exhaust on these vehicles does the vehicle require a ECU tune to set the exhaust sensors or engine sensors?

Thanks Guys

That's because you eliminated the catalyst. Only way to get rid of it is by putting it back.

Dammit

cool thanks for the heads up! do you think its worth having them back in? we have no laws here on that equipment.

loving your pewter baby..........

If you really can't take the smell you can put some race cats in place and will certainly get rid of the smell

jay_55

its not bad i was just worried that something might not be working 100% right and cause some damage that would cost $$$ to repair.

but if it just cats then im sure i can live with it

GT-ER

Just live with it.

jay_55

yeah im gonna live with it

cij911

Live with it ??? - No, put race cats on - no smell and you won't have any real world performance difference.

Sure if you want to pretend you are a boy racer, the car smell like a pig from the 70s, enjoy smelling gas, then keep it as is...

It looks good thought

jay_55

thank you sir.

will post up a sound clip as soon as i get a chance.

probably some power to be had from PROPERLY tuning the ecu to the new system, would probably lean it out some too, which will help the smell a bit

Who did the exhaust, Jay? If you're still keen on the parts we discussed, they should be available in the next 10 days or so

jay_55

i agree with that but i have a couple more things that i wanna do first before i do a major tune.

jay_55

Abel Dos Santos from Viper performance exhausts did it for me mate.

and you have a P.M sir

I second having race cats or you could switch to E85, as it has virtually no smell. Sure suxs getting gas fumes on your clothes each time you start up.

jay_55

do you know where i can get race cats?

PACougar

Brooke, are you remote starting the car while you're standing behind it I've yet to have gas fumes get on my clothes from inside of the car.

Many times when a new exhaust is installed you'll have a bit of a smell but it goes away after a day or so once the car has been driven. In your particular case it likely smells because you removed the cats. Give Kenny At Pelican Parts a ring and he'll answer any questions you have about a high flow (Race) cats for for your car. 310.626.8765 X 314

I hope that crossover tube isn't completely open on to the diameter of the pipe on the inside.. Did you see them build it or just pick it up done?

jay_55

I didn't get a chance to see them build it at all.

when you say that "the crossover tube isn't completely open on to the diameter of the pipe"

I don't quite follow what you say could it cause a problem?

jay_55

Thanks for the heads up busy looking at the site now

jay_55

with the amount of mods Brooke has on that CL of his his entire neighborhood smells his gas

The balance tube (crossover) that they installed connecting the two banks together behind the transmission. They installed the tube (the same diameter as the rest of the pipe) at a point in the exhaust where the pipes would be directing gases directly into each other.
This is counterproductive to flow.
It will be much worse if the hole that was opened up inside each side pipe where the balance tube is welded on is opened up to the full diameter of the tube, follow me? If there is only a small hole inside the balance exhaust pulses from opposing banks of the engine then flow will be disrupted considerably less.

A much more common approach is an X pipe style crossover or a smaller diameter crossover installed at at point perpendicular to the pipes, at a point where both banks are running parallel to one another.

jay_55

Okay i understand what your saying now

the size of that connecting pipe is the same as the rest of the exhaust set up.

would you recommend a x-pipe or a smaller connecting pipe? what would give me the best use for future mods?

A X pipe is the preferred setup if it fits. In your case you'ld it'd be best suited in the place where you have the first set of resonators.
