Default Custom muffler delete

So a few weeks ago I ripped off my mufflers just to see how it would sound. I ended up loving it, so I went to my local exhaust shop to have them fabricate a straight out exhaust. They wanted my mufflers to take the tips and the joint so that it could clamp right up with the rest of exhaust. I also talked to them about running 3" straight through and they mentioned it would provide no gains. It would essentially be a waste because the current system can already handle up to 600 or so hp.

My question being: he only put on a 2 1/4 " pipe for my axle back. Is this hindering the airflow?

Also, is it true that unless I went catless that my exhaust (all stock other than my muffler delete) there is not much more to gain to improve flow?

I'm actually extremly impressed that I have almost no drone whatsoever. Sounds great, wish it was a little bit louder even, and it has lots of pop and crackle on decelerating which I love.

Thanjs for the help!

small not noticable gain in performance with exhaust. its more of a sound thing. deleting the cats will make a difference but even that wont be huge. Unless you do the whole thing with long tubes I dont think youll "feel" it. But It gives the car a much better sound. X gives en exotic sound H gives a muscle sound. In all honesty other then Gears and good tires, and tuning on automatics ive never "felt" a difference when adding perfromance parts, the numbers do show on dynos though.

the stock exhaust piping is mostly 2.5-2.75 throughout underneath so you reduced it a bit not that you should really feel a difference like Shane780 said, it's for sound & a full exhaust is where you'd pick anything up.

So there is really no sense in me doing 3" pipes if I am happy with the tone now? I am going to do long tubes and and probably be catless. Outside if that though, there isn't much to really do? At that point I will have to put on mufflers I am sure because it will be DAMN LOUD. Lol

Longtubes or catless setups usually make some half way decent gains...exhaust in general is more for sound and how you want it to sound & oh yes I would definitely put mufflers on if you take the cats out! lol
