2.5" piping on a GS430
Honestly I didnt notice any loss in torque, if any thing I gained some. Perhaps its because the mod is so far back in the exhaust system (axle back) that it didnt effect bottom end performance. In addition, the car sounds mean, deep and throaty. I recommend it if you dont want to spend so much money on a catback that will yeild roughly the same performance( If any).
You gained performance....Really? How much HP?
Really? Why didn't you search the COUNTLESS of threads with this discussion going back 11 years

Really? Stop being a d!kc. Speak to me like an adult about this subject. Why wouldn't getting rid of restrictive mufflers not yield ANY gains? Many cars out there, even videos of cars on the dyno with just an axle back gain some sort of performance, what makes the Lexus different? Were the mufflers on the Lexus already super free flowing from the factory? I dont have proof of any gains just by ridding the mufflers, but it does make sense that it would. Do you, sir, have any proof that it does not? If so, I humbly step aside. Now, put all your sarcastic, belittling tone aside, please, explain to me why it would NOT gain anything besides a meaner, deeper, throatier exhaust note.

So all that aside. Everyone seems to believe that an axle back would not gain anything as far as performance goes, but, remember gents, engines are basically air pumps. If ridding a restrictive muffler will help the engine breathe, would it not make it more efficient, therefore, make more power? Even nothing noticeable, like a 5whp increase, there is still a gain. I've been searching for proof, like dyno sheets with just an axle back on but nothing. On the other hand, catbacks make roughly between 5-10whp, why wouldnt an axle back yield any gains. And I wouldnt think the pre-muffler and the resonators are restrictive at all.
Why would u make such a stupid comment like that after the whole point was discuss?
Keep it to urself..
If u dont have nothing positive to say please don't comment on my thread.

Again.. Why didnt you search info on your 2.5 piping before doing what you did rather, than doing it and whining "Guys ..?What happened? Can anyone tell me?"

I wasnt whining, i ask for an input, and i did search prior of doing this..
Not everybody have all the time in the world to read 11 year old threads, but i guess u do..
Good for u..
Now, if u dont like my post nobody is forcing u to read it or give your opinion.
Again why don't u search to do something else?

Hey max so I have a 2001 gs 430 with a fully stock exhaust and I want to know what to change out in order to get that v8 growl and more sound without losing performance, any suggestions? Muffler delete? Flowmasters? Or resonator delete?
