Here is the parts list of what I bought then had it all tig welded. At a custom hotrod and drag shop.

It was in comfort mode so don't have the burbles and pops but in sport mode the pops aren't as bad as the factory system. And yes my phone record sux it doesn't do it justice. In sound. Also there is no drone at highway speeds in comfort mode. Plus it's all manderal bent no crush bends. So there...

Here's a short clip. At idle it's kinda quiet.

Idle is kinda quiet. I also installed a turbo heat shield for the 6port manifold from verus engineering and the airbox resonator delete. And put a k&n drop in filter might go with misimoto airbox later dunno.

Everyone has there own likes or taste. I'm going for the mk4 vibes. Single exit. It was also considerably cheaper than going titanium. Also more durable being stainless steel. All the way and thick .47mm stainless hangars, and stainless v-bands. I didn't want to spend between 3-4k on a titanium...

So I just got my exhaust done and man it sounds great. I went with 3in t304 ss from the factory dp all the way back. Single exit. Used a vibrant ultra quiet resonator in place of the stock resonator. And at the rear vibrant universal turbo muffler. I have part numbers if anyone is interested and...

U won't get a cel but it may have an issue with going in an out of sport mode. I bought the valve delete simulator from ecs tuning for bmw as the plug for our supra is a 4 pin plug. Don't order the one from grimmspeed as it's only 3 pin plug.

If u want to keep ur valve open without taking out the spring until u get aftermarket exhaust this is what u need to not throw codes. https://www.ecstuning.com/b-genuine-bmw-m-performance-parts/dummy-flap-actuator/18302411427/

You will need this part if delete the exhaust flap actuator. The actuator has 4 pin connector. Grimmspeed only sell a 3 pin connector. The 4 pin I got from ecs tuning. Part number 18 30 2 411 427.

That one doesn't fit its 3pin the valve actuator is 4 pin. I bought that one in the Pic and don't fit.

Have u tried reset the ecu, by disconnect the negative terminal to the battery wait 30 min then reconnect the negative cable. Start let idle 10 min then take for a drive at that point the ecu Will re learn all values also clear codes. This includes the tcu for the trans.

Nice dp BTW. Gesi cats are a great well known cat. And being obd2 and epa compliant are great. I how ever don't plan on tuning yet either I want to keep my oem warranty. Lol. But once warranty is out I may go full bolts ons. Or if the motor ever goes I may rip it out and replace with a 2jz gte.

Thanks yeah I'm going to try to get one fabed from the dp all the way back. Not trying to cut the factory system up just unbolt take out and start from the dp and fab from there. But wanted to make sure before ordering parts. Also none of the car exhaust shops here will or have the equipment to...

Not trying to be funny it's just there is alot of conflicting stuff online some manufacturers offer exhaust with mid pipe diameter of 3in and some of 3.5in diameter and when I google what size diameter is the a91 exhaust it just gives a generic 3.5in and doesn't specify if that's at the oval...

Thanks there is alot of conflicting info online is why I was asking here. I would like to go the single side exit to. From spr-1 or made motorsports, but the cost is a little high. So for right now I wanted to do this and see how it sounds or preforms before I drop a whole lot on a full titanium...

Well apparently the a90 is 3.15 at dp exit, and a91 is 3.5 at dp exit it's why magnaflow has a system u can buy that comes with a 3' dp connection and a 3.5' connection so I'm asking if anyone who has a a91 if they can verify is 3.5' so I know what parts to order as I will send the car to an...

Stock dp. Stock exhaust ATM just want different sound I've had vibrant before on a 2017 Volvo s90 t6 with the exhaust flap on passenger side just like this set up and sounded good. But was a twin charged 2.0l 4 banger. As where this a91-cf edition is the 3.0l inline 6. I have simular set up on...

Hey so I'm looking to custom fab an exhaust for my 2022 a91-cf supra. And I need to know what is the size diameter of the outlet section of the down pipe. So I order the correct size piping, resonator, and muffler. I'm thinking about coming off the dp cut the suitcase resonator and put a single...
