Hey Guys, I just installed the Invidia midpipe yesterday hoping for a louder set up but I can't even tell the difference. Even when I floor it I can only hear my K&N intake. So I was thinking of doing a muffler delete and was wondering if anyone has done this with the IS350. Would it get too loud and drone? am i better off getting an after market exhaust?

 

Do you have a catback exhaust?

 

No, I just have the invidia midpipe with stock exhaust now and am looking to do a muffler delete.

 

Since you want loud, might be better to get the HKS high power cat back. It's going to be loud but not super loud.

 

I have the GReddy Evo3 and love it. Its loud enough!

 

From my experiences, the stock mufflers are pretty restrictive. If you delete the mufflers and keep the invidia mid pipe, it will be LOUD and drones like crazy. If you put back in the stock mid pipe and delete the mufflers, it will loud too. If you wanted just a little exhaust tone, keep the stock mid pipe and go after market mufflers. Invidia midpipe will rasp any aftermarket exhaust set ups.

 

Will it rasp with an Invidia Q300 axle-back?

 

I deleted my resonator and mufflers and opened up the axle back piping to i think 2 3/4 in(?) don't remember. It's pretty loud and and bassy. There's a bit of drone but I like it.
