This sounds good!
If you guys had a 6sp manual it would sound even better

Neil did those quad tips fit perfectly in the stock bumper ? or did you have to shave some off to make more space?

Also, does anyone have any more input on how a muffler delete will affect performance?

You're going to lose all your back pressure, so you're going to lose power.

If you care as much as you say, then why not go and do it yourself instead of waiting for someone else to spend their money?

Wow, talk about bringing back from the dead.

I never said "how much" I care. You are putting words in my quote.

I do not care enough to spend the money. I am now going to dinner and a glass of wine with the $$ I saved.

If you're that worried about performance, you could get a straight through muffler which will keep back pressure at low speed. Then at WOT it will act like a straight pipe with better flow.

Hi Neil
can you send me a pic of your car from the back. I was thinking about the dual tips and would like to see how they look from a little distance about 10 ft away
thank you

I'm seeing some people say there is a lot of drone and some say there isn't. I'm considering this but still not sold on it because of the drone controversy. Are people using different size piping that could cause the drone?

Sorry for bringing back a month old thread, but has anyone done this on their leased IS lol. My lease is not up until 2.5 years from now but im considering doing this just kind of scared of cutting my pipes and welding. Any way to unbolt and have the exhaust shop put flanges on the pipes theyre making in order to switch off?

Looking to do this to my 4th gen GS 350. I wonder if it will sound the same as the the IS and the RC350 motors. No one on the GS forum seems to have done this.

Looks like you'll have to lead the way
