Most stock sounding catless H pipe

The title says all. I'm looking for the most stock sounding catless H pipe out there. Please let me know what brands. I know It won't be the same. But I'd like it to be close. Also, will the cats make that much of a difference in sound? Any info is greatly appreciated

I think anything catless will be a lot louder than stock.

Are you wanting to have a louder stock tone?

The h-pipe really doesn't define the tone of the exhaust as much as the mufflers do. The catless h-pipe definitely frees up the exhaust and increases decibels

If you really want to keep the "stock" tone, keep the factory mufflers and just add the off road h-pipe. Any brand will do, really comes down to price. The Pypes offerings are a great value midpipe.

I would recommend a catted aftermarket mid pipe with stock muffler perhaps. It will make a noticeable difference in sound but not too much like op wants

Catless equals load and some think H pipe sounds better than x pipe.

I think he meant catless is loud.

But yea I've heard from a lot of people that they like the sound of an h pipe over x pipe. But I think more people go with x pipes. I think it's because more company's produce x pipes. Only a few h pipes

So catless will just make it louder and won't change the actual sound and tone of the exhaust or?

Mildly change the tone. It will be significantly louder.

Yes, the decibels will be much higher with a catless pipe. The tone will change slightly as the factory mufflers are funneling more gases then before.

If you really want a different "sounding" exhaust with a completely different exhaust note, get different mufflers. If you want keep the current exhaust note as close as possible but make it louder, get an offroad (catless) h-pipe. Or spend big bucks and get electric cutouts.

I'm happy with the way my car sounds. I just don't want cats. I have slp 1s catback and I just wanna delete the cats. I'm very very happy with the sound I just don't want cats so I'm seeing if I can keep the tone while still deleting cats

You'll also need to address the rear O2 sensors when cats removed. Depending on year, will require new tune.

This just my opinion but I think the loudmouths don't sound that great without cats. With an h-pipe they're tolerable but an x-pipe makes them way too raspy for my taste.

They do sound good on F-body cars.

But if you're happy with the sound I'd opt for a prochamber or h-pipe. Maybe listen to some 2V's on youtube to get an idea of the sound. It will change slightly depending on the midpipe, and will definitely be louder.

Why do you not want cats? You want it to sound catted but you don't want cats, makes zero sense.


If you think cats rob a ton of power, good aftermarket cats do not rob really any at all, not at your power levels. If you want catless due to cost... well you have to pay to play. You want it to sound catted you need a catted pipe.

I just had a Jegs H-pipe and a Flowmaster Force II system installed on my son's 95 GT. It's catless now and sounds great. Very reserved and no resonance (the car is a convertible). I would recommend to anyone wanting that nice deep tone without the obnoxious volume!

Put hi-flow cats on mid-pipe of choice, maybe a MAC ProChamber for mellow rumble.
