Basically fited a 3.5inch exhuast to my 33 with 270rwkw and its got a valve inside the exhuast, its the dodgy version of the varex

the exhuast is only sort of quiet when the valve is fully closed, but the gases hav no where to go.

Is it ok to drive around like this to get less attention or is the pressure to high? ( il be driving under 3000rpm)

What do you mean dodgy version? Is it a Varex or a knock off? Or one of those Apexi sandwich valves?

Its a knock off

its a butterfly valve in the exhuast and when its closed its like putting your hand lightly over the exhuastvpipe to slow flow

its still got lots of flow i imagine becuase its stillso damn loud but lags like all hell when closed

Car still starts up fine when valve is closed fully

( i imagine even when the valve is closed fully its not the same size as inside diameter of pipe i.e. Its a 3inch valve mabye, or it dosent close completly)

cheers

Yes I know what a Varex is I have one, I'm saying where in the exhaust is the valve? In the end muffler like a Varex or half way along the exhaust like the Apexi wunder valve? Varex use recirculation through a smaller hole that leads into another muffler...it's a much better/safer design when closed off than the Apexi valve. Either way it should be fine, just avoid boosting and high RPM.

you can drive around with it closed up as long as you arent accelerating hard. it does restrict your exhaust flow a fiar bit, but if you take it easy it will keep you out of trouble :thumbsup:

Are you going for an EPA test? No mufflers will be illegal noise-wise, even with that valve. The standard system is 88 decibels and the legal limit is about 90 :/

      thanks for heads up on actuators - will sort something as back up or solution as yes dont need that have enough trouble but no doubt some addition of something to spares boxes is required yes have a clue about WTAC but nothing has been officially put out yet so will wait to see exact details Pro class is, has been and will become a draw card for lap records and one off builds for show and thats about it I think - be interesting to see how open they make it Pro am is the old Pro in reality Open class will be split into 2 with slicks and 050's with no doubt slight variances in allowable drivers and changes in aero Clubsprint + apparently a true street class   They have to and are refreshing it all and bringing things up to current standards and need to 100% adhere to rules because whether people like it or not / or say it or not - for alot of competitors it is sheep stations and has been for a while when Im getting told I was illegal because i cut my rear bumper too high and yet others where in the grey areas of legality with everything from engines, suspension, ride heights and more serious influences it actually got quite out of control and heated this year so as much as I may be impacted by some of the changes and prob spit the dummy when I have to spend money changing things I think its a good thing for all

      I can’t tell if it’s suspension related or maybe wheel bearing or motor mount.  IMG_6209.MOV

      Start with a multimeter, and see if you're getting power at the TPS. There should be a manual for your car somewhere on these forums and it'll have the info for what closed TPS signal voltage is, and how it should sweep to full throttle. Same as for other sensors / valves.   Have you checked things like your base timing etc? See if anything looks amiss there too?

      here are 2x options to consider: https://www.selby.com.au/price-promise/tonewinner-sw-d6000-subwoofer.html https://www.apollohifi.com.au/svs-pb-3000-ported-subwoofer-black-ash-pre-order.html I'm waiting for a good BF/CM sale and will pull the trigger on a new sub, I do like the SVS PB-3000 (13") but you could nearly buy 2x Tonewinner D6000s (15")
