With the cats in tact, is it extremely loud? Got a buddy with a 13 Camaro and it was pretty loud with mufflers removed and he has 4 cats

Yeah it's pretty loud and sounds like poo. I ran out of wire when putting some tiny mufflers on, forgot the name, and went to get some more wire with one muffler. Wouldn't recommend.

Did this recently after spending a day trying to align my Corsa Extremes. Rain caught me mid adjust. It's fun....for a little bit. Driving with my windows up gave me a headache in about 10 minutes. The cabin resonance is insane.

Nah ... I'm running LG LT's, no cats with B&B bullets. To me it's how these cars should sound.

With your helmet on ,you don't notice the noise (at the track).
After 6 months and a drive for 3 hours, I called uncle.
I don't run catbacks just a small muffler off of the x-pipe.
Good luck......I say, GOOD LUCK!!!!!

Not something I would do - but only one way for you to know if you like it.

How would no mufflers compare to something like the SLp loudmouth? Looks like its just a few pipes and tips... for 700 and change hahaha.

My 99 has cut outs that open/close with a switch. I would never drive with them open for an extended time as it get obnoxious after awhile. I have long tube headers though so it would be slightly less loud with stock headers.

I scooped up a set of borla straights while my headers were on preorder just because they were dirt cheap and I knew I could get my money back out of them when my headers arrived. I planned on running headers through the stock ti exhaust.

the straight pipes alone are really loud. Definitely drone some and don't have the cleanest sound.

I put the the headers on and left the straights on just for ***** and giggles and was so surprised by how much more tolerable the sound was. It's still very loud but the drone is very reduced.

It isnt for everyone, but neither my wife or I mind it, we've been on 1500 mile trips in the car where neither of us complained about the noise or getting a headache. In all honesty my tire noise is louder now that I'm getting close to wearing this set of tires out.

Moral of the story is: with cats and stock manifolds I don't really like the sound. With headers I do.

If you plan on just removing the mufflers (no axle back pipes) the done is insanely bad. and the coupes glass seems to amplify the problem. With pipes to the back, its loud but my girlfriend likes it and we don't have to talk loud to have a conversation. The worst drone is about 1700 to 1800 rpms. You know cruising speed :/

I did this in 2005 as the flange where the muffler pipe bolts to the catalytic converter flange broke.

Pulled off both mufflers, drove around for years, at first it was awesome sounding, later I decided it sounded redneck.

Ended up buying used factory C5 mufflers and new gaskets, put them on and noticed it had a deeper more rich bass like rumble vs a higher pitch loud rumble.

Also with no mufflers and letting off accelerator pedal while in gear coasting in a parking lot at slow speed (6 speed car) you could hear what sounded like exhaust air going backwards, reminded me someone breathing weird like a struggle to inhale.

Also don't forget the loud backfire sound after you get on it then lift off pedal!

Not as loud as that old POS John Candy drives that backfires on the movie Uncle Buck, but that noise, it's a unrefined sound on a nice car such as a C5. Lol

I say get long tube headers and high flow cats and keep the factory mufflers for a nice rumble.

High flow cats and an x-pipe along with an axle back system is true v8 music.

The x-pipe is the biggest key to the puzzle as it blends gasses from each exhaust bank.

I remember back in the day when just a good no cats dual exhaust systems with proper mufflers would sound great. Still to this day the best sounding exhaust system ever had was on a 72 Monte Carlo I had. It was a dual 2.5 system with turbo mufflers. What brand? I don't remember but they weren't they typical quiet sounding turbos. They were actually quite loud. I'm thinking they had glass packing too.
My wife once owned a a Trailblazer SS which had the muffler removed but still had the resonator intact. It sounded great. Just the perfect balance between loud and quiet. Can hear it idle pretty good, nice rumble at cruising and when you got on it, it sounded really really good, yet didn't drone at highway speeds.
I've also owned a 2002 Trans Am. Loudmouth 2 exhaust, no cats and longtube headers. Brutally loud and just too raw for my taste.

I've got LT's, an off-road X-pipe, and Borla straights.. it's definitely loud as hell but I love it.. definitely not for everyone.. had a buddy drive it around the block for me while I stood in the driveway and it gave me a chubby

the mufflers had been removed from mine when I bought it. I like it so much I scrapped my plans of buying an axle back system the first day. Now that might change when I get longtubes and remove the cats.

at idle it is just slightly louder than stock. and up in the revs, at least to me, it has more of a sports car sound vs the annoyingly loud deeper muscle car sound that my best friends LS1 camaro with flowmaster has (which i think doesn't belong on a vette).

I will get a video of startup here in a few when i go to work

Everyone's ears are different! Only one way to truly find out!!

Keep mind if the axle back is removed and it's just the h-pipe blowing hot air onto the rear leaf spring it will cause the spring to deteriorate.

sounds like trash to me, only way no mufflers sound descent, is if there's turbos infront of them

Stephen Meredith

Doesn't sound like trash to me at all. I like it better than the $1K+ muffler sounds
