shockwavexr6t Member 50 Member For: 19y 16d Posted 04/12/05 12:50 AM Share Posted 04/12/05 12:50 AM a three inch mandrel bend is the same as twin 2.25 standard system you would be wasting money. If you are @ 300rwkws + then a exhaust change would be good to releaf back presure, then consider a 3.5inch mandrel bend system.. heaps more flow.just my 2ccheers Link to comment Share on other sites More sharing options...

Single piple vs splitting the pipes up.Have a look at the link I have posted, where you will see dyno sheets showing the increase in power when the system were changed. Doesnt look like a waste of money going by those results. Link to comment Share on other sites More sharing options...
Guest mercurysteve Guests Posted 04/12/05 10:18 PM Share Posted 04/12/05 10:18 PM I had a custom built 3" exhaust and had the car dyno'd before and then straight after, again a week later to see if the shock results were a one off.Bottom line, my car went backwards. Lost 12rwkw on the standard system and it droaned like a biatch. Even with 2 hotdogs... I sold it, put the stockie back on, removed the centre muffler and "ho flowed" the cat, picked up 15rwkw on the original setup. No 3" system for me. Hope this helps some, talking from experience.

Guest mercurysteve Guests Posted 04/12/05 10:47 PM Share Posted 04/12/05 10:47 PM Can't beat the APS jobbie IMO Just need the MOOLA and I would have one in a heart beat. Link to comment Share on other sites More sharing options...

I was told it will be much cheaper then the APS system and other on the market, should be available in early Jan 06, once it is released and pricing available then we can see if it is worth the upgrade.

I am in the middle of testing my new 4 inch system, should have dyno results within the week and a sound file. P.S the APS system at 1800 bucks is bloody cheap for the quality of the work. Considering there are some shops charging 1500 to 2500 for bloody press bent systems and ppl are paying it. Link to comment Share on other sites More sharing options...

Everybody loves it (barring my mum who thinks it sounds like a tractor lol) mercurysteve, something doesnt sound right there mate, as I went the opposite way, I gained power (as my dyno sheets show in the above link). Very Very strange. Link to comment Share on other sites More sharing options...
