So after asking youz guyz waaay too many questions, I went down to a small locally-owned muffler shop & had that mid-muffler brick cut out & replaced w/2.5 straight pipe.

Executive summary statement: I can't possibly imagine a better value-per-dollar spent than this simple mod. Totally a good idea. Totally worth it. Very pleased.
(I have an 07 Type-S 6 spd.)

The exhaust note is definitely improved but the car isn't now "loud." If that makes sense. The change is more of the deeper, more rumbly variety, & mostly at the bottom of the rev range. From off-idle to about 3,500rpm --right in the 'around town' sweet spot-- is where its most noticeable. Under WOT up above 4,000 you can't really tell much difference from stock; but the engine is doing most of the wailing then anyway.

Now, I notice it b/c I own & drive the car regularly. To the uninitiated I'd say the sound mostly matches the car's looks. Its not so over-powering that the moment you fire it up everyone's head w/in a 50-ft. radius is going to swivel around wondering "what the hell is THAT?!", and at idle there's really no difference from stock at all. But once rolling its just a little bit deeper, throatier, a little more aggressive under mild throttle & very noticable right at shift points under normal driving - which for me tends to be in 3 - 4,000rpm neighborhood.

Coming down my street allowing the car to coast/decelerate at about 2,500 in second gear was nice. It has just about the right amount of rumble. But keep in mind this is from a 50-y/o father of 3 who's trying to let the neighbors sleep, not a 25-y/o bachelor who's trying to wake the dead.

As for the much-dreaded 'drone' and/or 'rasp' - there is none. At constant-rolling speeds its completely stock-sounding.

The shop charged me $50 & it took them about 20 minutes. A little steep but I wasn't gonna quibble over a 10 dollar overcharge, espec. since I can use them again to do work that's ,....*ahem*,...close to some legal lines.

I'm going to rock this for a while and see if it grows on me. In another thread one of you said you additionally deleted the cat and that really brought a nice deep boom. That may be the next step. But for now I can say this; if you've thought or are thinking about doing this there is no question its the best $35-$50 bucks you can spend...unless you know some girls in Tiajuana.

I look forward to each new thread keeping us up to date on the exhaust mods you undertake.

Anyway, glad you like it

Good point. I'm outta here for the night but maybe later when I get back or at some point over the weekend I'll re-post this into that thread & then delete this one. ...got all excited and everything

Nice work, I've been meaning to do this plus the magnaflow res

DerrickW

Read from some on here that the Magnaflow res was a waste of money and, once the mid-muff was gone, they couldn't really tell much if any of a difference. I dunno. I've ripped out the intake resonator + mid-muffler. I'll go j-pipe next I think and just live with the stock exhaust resonator

I love the sound my car makes without the mid muffler. OP, you're right, it's a great easy mod.

How about some audio? I would like a little more sound but don't want to obnoxious

Scottwax

If you go with a long tube j-pipe that deletes the 3rd cat, you definitely need a resonator but it doesn't have to be the stock one. I originally removed the resonator after the j-pipe (already had removed the mid-muffler) and while my car sounded fine at idle and full throttle, there was noticeable rasp at part throttle. Added an aftermarket resonator and sound it right where I want it. Still very quiet at freeway speeds too.
