Exhaust Help

Hello NS, I know there are better sites to find this stuff out but this is just an much easier method.

So my 1991 mk2 VW Jetta GLI has an exhaust leak out of the resonator it only has a cat, resonator, and something inbetween the two that I'm not to sure what it is, it has no muffler, so its already fairly loud. I was thinking about doing a full straight pipe (No cat, resonator, etc) but I was wondering if it would have a better sounding exhaust with the cat left on. I don't want the whiny noise the Hondas make but more of a deep groan. Any suggestions?

well I'd leave the cat on. partly cause it actually does help your emissions and partly cause I'm sure it's a legal requirement in a lot of places (it is here).

If by 'sounding better' you mean being quieter then a straight pipe will be about the loudest thing you could do. Without investing in a muffler the best option would be to repair the hole. The cat will muffle sound to a certain degree too.

Dont go just straight pipe all the way through, get a cat and resonator, you still need some back pressure plus the resonator will help deepen the sound

Thats what I want is the deeper sound, I just don't want to invest money into a new resonator.

Hondas don't make the whiny noise, it's the ricer fart cans that people associate with Hondas that make them sound like a pissed off bumblebee.

Every Jetta with a straight pipe is going to sound pretty crappy, any 4 cylinder (minus subies with UELs) is going to sound pretty similar.

If you are trying to go for the best sound rather than the most noise, you will probably want to get a high flowing cat, resonator, and muffler, and some larger diameter piping. If you can source all of these parts individually you can have a pretty great sound for relatively cheap and shouldn't cost to much to have put together at an exhaust shop.

You could just get a higher flowing resonator and it would sound decent

Yeah a kid from my schools jetta is straight piped and it sounds like shit. Most Hondas do sound bad with any aftermarket exhaust, the only good NA four cyls that sound good are 4g63s and subarus if done right.

It's a 91 Jetta. I'd highly suggest not putting a lot of money into it. So just repair it.

Putting WeaponR headers and high flow cat but keeping my exhaust stock on my TSX. Pretty stoked to see how it turns out.

I think I'll just buy some piping and take out everything but the cat, I don't really care how "good" it sounds as long as it pisses off the neighbors.

i cut the exhaust off of my mk2 jetta about 6 inches past the cat and it sounded so shitty. backpressure was awful. that gurgling sound of burning gas in the exhaust wasnt nice. i'd suggest getting a high flow cat, wider pipes, and a resonator. your ears will appreciate it.

Do you think if I just left the stock cat on and got some wider pipes it would still sound shitty?

Taking everything off and full straight pipe will probably get you a few tickets but it's probably worth it

I'd say find the leak, repair that, and see what it sounds like after. If you don't like the sound, I would straight pipe after the cat, possibly getting a newer one that would help with cleaner emissions. Cats are typically pretty free flowing so it wouldn't make all that much of a difference with sound and air flow.

Meh. It'll be deeper most likely. Straight pipe it after the cat with a decent looking tip on the end could be aight.

That's what I'll most likely do, I was tossing around the idea of having a side exit exhaust but cops wouldn't be too happy about that.
