dump/front pipe performance?

[GTS-t VSPEC]

It won't make as much difference if you still have a standard exhaust blocking the exhaust gasses.

Heres a before/after dyno between stock and custom 3" front/dump/cat.

I'll be buggered if i can find the thread i created 6mths ago when i did the upgrade.

benm,

Nice gains across the board. It's a cheap and effective mod:D

[pushead]

very effective and nice results benm. what i was looking for.

[benm]

Yup i noticed the difference immediately. Was money well spent thats for sure. Just don't forget to buy a 3" Cat also.

[pushead]

but i heard 3" cat doesnt give as all that performance? is this true?

[benm]

No point trying to connect a sewer pipe into a garden hose....

[GTS-t VSPEC]

It's better than the stock cat, but no cat is better:D

[pushead]

lol GTS-t VSPEC, you are the ultimate whore

@benm: makes sense.. might need to get one now.

[coco69]

hey pus,

what brand dump/front you get?

[Guest Robo's]

Its the 3 inch flanges thats going to help you out rather than the stock 2.5. Its like hitting a brick wall.

[coco69]

you guys tried the catco 3" pipes that are available in the threads here?

they prices are good, howz the performance?

[pushead]

hey coco69 dude, the front/dump pipe is catco 3".

I also realised that after changing it the idle seem to jump up and down sometimes? did anyone also experience this problem?

[coco69]

how much u pick it up for pus? is it the ones thru BATMBL?

i rkn i need to do my front end exhaust stuff...

my system is buggered... got stock fronts, 3" cat, 3.5" pipe which splits into dual 2.5"pipes and goes to twin barrell mufflers with 3.5"tip each. and one of the pipes has a hole in it and its muffler has its glass packing all fallen into the muffler.

gayness!

[pushead]

yea dude. PM Batmbl for it. highly recommend...

[pushead]

also does anyone know why my idle keeps to go up then drop down alittle sometimes? i was thinking it might be the ECU needed a reset due to the new front/dump? can anyone confirm this?

Hiflo cats, 3" cats, to be honest does the dollars spent really justify the power gain's? Granted your exhaust will only flow as much as the smallest part is but does $250 spent on a hiflo cat really make that much difference? I'd love to see a before and after dyno/test on this. I would think the difference would be negligable.

Got a 3" dump fitted today at Turbo Exhaust Centre in Wetherill Park, Sydney. The guy makes them in-house and claims that he supplies most major performance shops in Sydney.

Very nice piece of work. Fully mandrel bent and beautifully crafted flanges on the turbo end as well as at the cat end. Bolts straight up!

I highly recommend them. $330 supply and fitted.

I got a 3" Trust MX Front Pipe + 3" Catco Cat + 3" Trust MX Cat-Back. But I'm still using standard dump pipe which connects the std turbo to the MX front pipe.

My idle is stable now at 750rpm, not jumping up and down, so your problem may not be because of the ECU. But try disconnect your battery, pump the brake pedal a few times to discharge any electrical residue to reset your ECU and see how you go.
