R18 muffler delete isn't loud enough, what now?

So I took out the muffler and welded a pipe in its place. I thought it sounded really nice until I heard it from the outside, it has a good tone with no rasp but it just is so quiet. Anything I can do to make it louder without ruining the sound?

Yea buy a real full catback exhaust and while your at it a Megan or weapon r down pipe to start. You really need to get rid of the cat if your looking for more sound. I have a full setup and mine sounds great but not pound and annoying that's what the skunk 2 exhaust was made for

Good response but every downpipe I've heard of causes major problems.

In what ways would a downpipe hurt? Dependent on where you live, it may or may not pass any inspections. The only thing it would do is put a check engine light on your dash. You can delete this with a FlashPro

Correct you need a down pipe if your trying to make power. All about freeing up more space

How did you weld a straight pipe to that flange after the resonator?
Does anyone just sell straight pipes with the flange?
I don't own a welder but I love the sound without the muffler! \_(ツ)_/

Is there a reason you don't want at purchase an actual catback exhaust?

All muffler delete sound like all rasp all rice and no power added

I don't want to spend money on the car. I want to tinker with it but not spend on it. I think it's plenty fun to drive and looks great as it is stock. However the muffler delete has been really fun in getting to feel the power of the car through my ears (not just my seat).

But where can I get a pipe to attach in place of the muffler? Is that a standard flange which connects the resonator to the muffler and if so is there a place to buy a simple pipe welded to that flange??

Simply remove the catalytic converter and add a down pipe, I'd recommend 1320 performance, does the job and with a decent price.

Keep in mind it will be really loud more than you think.
