i recently got epa'd so im taking the 3 and a half inch exhaust off and putting the standard one back on but while i was at the workshop asking if i could borrow a standard item i saw a 2 and a half inch exhaust that looked a bit more restrictive but at the same time it looked alot more quite and i should be able to use that and not be bothered by the epa anymore but now my question im fairly sure ill lose power but how much

my car is fairly stock pod filter exhaust boost controller and i have an intercooler about to be installed i always thought the 3 and a half was too big for the amount of mods i had but i always thought less restriction more power ....i would like to hear your thoughts was the original exhaust too big for the amount of mods i have,will i be better off with the 2 and a half

thanks

i had the 3 and a half inch exhaust tested before i took it off 98- to 101 decibels obviously not legal so the guy i go to had a kakimoto exhaust 2 and a half inch it made a huge difference 86 decibels at 4800 rpms and i still have a 3 and a half inch front pipe i didnt think it'd be able to pass with the front pipe

      Duncan's V37.......race car?

      Thanks for doing that Duncan! Makes you a good person in my books. We don't get kangaroos or wombats here. But we have bats and it's similar. AFAIK it's often the mums with a baby attached that get hit because they drop lower when starting from a tree. If you hit an animal, check on it. https://www.ifaw.org/au/resources/wildlife-rescue-app An app to get the closest wildlife rescue contact.

      Jacks that fit under GTR lips that can reach the subframe?

      My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though.

      Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno

      Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.

      BTW I measured the jack I have, it is 70mm at the saddle but you only have about 700 until it returns to 150mm high at the cylinder so it is good but no magic bullet.
