Hey guys I just replaced my muffler with an HKS hi power and I’m looking to sell it. Idk if anyone wants this but if you are trying to get your car back to stock/replace a stock one that’s broken I’m your guy. It works perfectly it’s just been around for a while. I didn’t replace it because of a...

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...

I just got a megan y pipe and I need to cut out the stock ones but I dont know the bolt size that I need, can anyone help? It the 3 bolts that connect to the headers and the 2 bolt that connects to the resonator.

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’m thinking about getting some headers for my 2002 IS but i don’t know anything about o2 sims or how the sensors even work, if i were to install the headers without a sim will the car even turn on? Or will it turn on but my mpg will go down a lot and i’ll get a CEL light, any help would be...

Hey Guys. Really need some help. My Aristo Swap 2jz gte twin turbo IS300 had 3 inch straight pipe with catback at 14.5 PSI. Unfortunately, I had to change my exhaust to 2.5 inch with filters due to law issues and I saw the PSI drop to 7 PSI and I have lost significant power. Is there anyway to...
