    Just got a new y pipe and my o2 sensor is super stripped and I’m guessing by the look of it that it hasn’t been working properly for a while… will it hurt to just block the exhaust off and delete the o2 sensor? I drove it for a while with the o2 sensor dangling on the ground and other than the...

    Hello, I currently have a Blitz Nur Spec axleback fitted to an Altezza RS200 6MT and am looking for options to complete a full system. Considering the Fujitsubo Power Getter center pipe to replace the factory catalytic converter and midpipe, along with a Fujitsubo Super Ex Header Exhaust...

    Hello, everyone, I'm considering purchasing a 2007 Lexus IS250, but upon reviewing the photos, I noticed a dual-tip exhaust on one side, rather than the usual one exhaust on each side (I've attached a photo of the listing). What could be the reason for this? Is it the result of an accident or...

    Hi guys, I have an 06 Lexus IS350 in the rust belt. My midpipe is rotten enough to have about 4 holes in it.. cant pass safety. Instead of welding it I was thinking of an aftermarket midpipe since welding it may rust the rest of the exhaust out? The cats are still good. I was considering...

    If I was going to cut the muffler off and replace with pipe, what size pipe would I need? I’ve seen some people say 2.25” but I’ve heard other say 2.5. I’m not sure on the length needed also. I have an 03 is300

    One day when I stopped driving I walked to the front of my Is300 and heard my coolant boiling (it was a hot day). I replaced the bad radiator cap and drove it home when it read as overheating. Wasn't sure if it was air or if it was truly overheating but I flushed it and replaced it anyway (the...

    Sound clips from my stock 2jzge. I had just catless headers and a muffler delete. Kept everything else stock. Imo this is the perfect balance of not too loud when you want it and loud when you get on it. It did small pops. Video: is300 Sound Clips - (Catless Headers & Muffler Delete) 2jz GE -...

    Has anyone ran a Greddy RS catback exhaust with the 3rd cat deleted and stock headers? I want to quiet down from the straight pipe it has on it but no point of spending the $800cad on the full catback for it to still sound obnoxious.

    Hello all, I have an 04 IS with the stock GE still in her. It came with a JIC Titanium Axle-back exhaust and have been told it's been discontinued and worth some good money in good shape? Can anyone give me some insight on original MSRP etc...? Thanks, Hayden

    I have an '03 and am looking for cheap replacement for my oem ones that have gone bad on me recently. I found a reasonably priced one from protuninglab but it doesn't have any catalytics on them. Since I still have one catalytic on my Megan Racing Y-pipe will that be able to get me through...

    I just picked up my IS about a week ago and the exhaust or something has the horrible whistle when I rev or get on the gas. I don’t have a turbo whistle lol and the whole car is stock. Was wondering if any has the same problem and if any one knew the fix to this problem.

    Hey all. So right now I just have stock exhaust (very sad) and I’m definitely wanting to upgrade it, and I think I want to go the dual exhaust route. However, I was thinking that if I do dual exhaust I would rather it be a “true” dual exhaust, as in keeping two pipes all the way from the...

    Okay, so i was looking to change up my exhaust setup from an eBay catback to possibly an Apex'i N1, but i found something interesting... It seems that the right side pipe from the 17-19 IS may fit the first gen (2001-2005) is300's, AND is much more cheap ahem affordable than other catbacks...

    So I just bought an HKS Hi-Power axleback exhaust and the rest of my whole exhaust is stock. Im just wondering what I should get next, y-pipe, catback part, or headers. I wanna make it louder so what kind of setup would make it louder and maybe backfire a bit. Want to hear your opinions and what...

    Bought this car before smogging (like an idiot) and failed two different smog places. The y pipe containing the 3rd cat was taken out when putting in a custom exhaust. Part for reference: Thankfully the manifold wasn't touched, just from the manifold back I think. Does anyone know if I can...

    I'm currently looking to buy a Tanabe Medalion Concept G exhaust for my 01 IS300, but every website seems to cancel the order once its placed saying the product is unavailable. Does anyone have any experience in buying exhausts, in particular a Tanabe, in recent months? Or maybe now that the...
