had the tanabe on the 99gs300, loved how it sounded on load. later added the megan y pipe, made it sound a little bit more raspier and throatier...

the same tanabe but on an 01gs430, first v8, thought my car was f***ed up, but the odd rumble is suppose to be normal! either way, sounded good. now installed the megan y pipe modded from an sc430. it quiet it down, but the growl is coming back with the pipe "breaking in". however, now it has a mid-to-high pitch rasp noise on load at 5500+ rpm. friend thought i boosted the motor...

I removed those 2 long resonators on my 400, kept the one just after the Y. Cabin sound hardly changed, just a bit louder when you step on it. Gives it a decent growl from outside though.

To answer your question, Yes i regret trying out 4 different set ups before going back to OEM..

I agree. I had a pair of 5Zigen Megas with a resonator delete, no gains. Same set of Megas on GTE swapped GS430 with a full 3" DP, major gains and relatively quiet I might add. Same Megas just bolted on to the stock exhaust piping on a 300, a little sluggish during mid range but had a nice quiet tone. I'd prefer axle backs on the stock GS300 just for the subtle tone.

no drone from resonator delete

Hello, I have a GS4 and wanted it to sound like a V8. I had a local muffler shop delete the 3 resonators and keep the stock mufflers. Sounds GREAT and not loud at all in cabin...no drone. Easy mod and worth it
