High flow cat or cut off back two?

What should I do? I want a little more noise. What will sound better? Is there any advantages to one over the other? I would imagine the high flows would be louder than removing two correct? Either way I would still not throw a code, or would I?

Spend the money on a full exhaust, don't go broke dick bro. A full exhaust is well worth the money

high flow cats and a cat back or axle back is cheaper than a full exhaust

Call me broke dick, but I went the route of an x-pipe and removed the resonators and 80lbs of muffler cans and mine is loud and very aggressive sounding at WOT. Idle and regular cruising is zero drone and very driveable.. Only downside is the decel pop.. But that is an acquired taste.. I can provide you a couple of vids of before and after for some sound comparison..

For more sound and no worries of codes all you need to do is resonator and muffler delete...

Most muffler shops will do this for AROUND +- 200 bucks...

I have the borla atak catback and don't want to hack into that. I would consider headers but like the idea of these bolt on HF for warranty reasons and no need for a tune with these unlike the headers. Cheap dick lol everyone is getting all huffy. Call me what you want. How much extra money did you have when you were 16?

Haha, difference between being smart and being cheap. Muffler delete cost my 70. And is the same as a loud mouth exhaust,.that's just smart., x pipe it and now you have a cat back for a third the cost, again, smart. Throw on hf cats and booya, you just added about 15hp to the rear, and are now the loudest guy around , making more HP than the guys who paid double for a cat back, which adds 0 HP BTW. Is go that cat route, I know, because I already did everything I just wrote about...smart.

lol...

Had a guy at a car wash (Same car) show up and give me crap about not spending 2k on an exhaust. Was standing at the exit and had 2 people ask me if that was my car...and tell me how good it sounded. The guy with the 2k exhaust (mad cuz noone said anything to him) looked under my car and promptly told me that my exhaust looks like crap.

Told him to keep laying on the wet ground staring at exhaust pipes....makes him look more learned...

And i got this driving away... for 200 bucks...

sounds like total . That's cool that you like your exhaust but I think the 2k exhaust is worth it. Call me stupid. I know I would go crazy with cut off exhaust.

so, its worth 1800.00 to you to have an exhaust kit thats in pieces put together and welded instead of having the stock exhaust cut off clean and welded (or slipped together so you wouldnt see the cut)? I guess I dont understand because for that 1800.00 I could get high-flow cats, cold air intake and a tune...

So, what IS the difference between having a slip-together exhaust kit or a weld together exhaust kit, versus having a few custom pieces slipped on and/or welded? I mean, its all on the under side of your car and unless your 4" thick, I seriously doubt anyone is ever going to see it... so it cant be a "bling" factor.

From someone that has had both a muffler delete and a complete built cat-back....I will say that for the money the muffler delete is absolutley the way to go.

Do cat-backs like Borla or LG sound better. Well...that's all personal preference. Then again they are about $1k more.

For me I went with the muffler delete right off the bat because I had put as much money down to buy the car as I could and I knew I still had other mods I wanted to do like stripes, shifter, springs, etc. The muffler delete was a temp fix until I had the money to do a full exhaust.

I ran the muffler delete for a good 3,500 miles and it was great but would've been too loud for my taste with headers. If it weren't for me buying headers the muffler delete would still be on my car.

BTW: there aren't any cat-backs that I've heard of that cost $2k. Most are around $1k - $1200.

I think someone just likes to boast about how much they've spent on their car, regardless of the stupidity displayed in their statements. Fact is, if you can make your car sound and run just as good as the guy who paid 8K, and you only paid 300bucks, your awesome. i say the man who paid 300bucks is using his head! I've learned just let the stupid people stay stupid, there's not point in trying to push a chain...

I got my full catback Magnaflow system brand new from JDP Motorsports (vendor here) for $600 shipped. Just this past week I opted to get the TruX-pipe (to replace the resonated x-pipe that came with the kit) which was $60 shipped. total cost $660 for a full cat back system the way I wanted it. I agree the muffler delete is a great inexpensive way to go, but for $660 for a full "custom" catback... you can't beat that either.

They should be the same for L99 or LS3.

You can double check with SOLO but I'm pretty sure there is no difference.

The solo L99 cats have a flex pipe on them the Ls3 is solid steel they should both fit though. How much for the Solo cats?

The Solo high-flow cats sound great on an L99. They are quite a bit louder than 'stock' even without removing the resonator or changing the stock mufflers.

@casper how do you figure an aftermarket exhaust doesn't give you any HP gain but a muffler delete does? Most aftermarket catback exhaust are dyno proven. Most of this comes down to budget and preference. I'm with danhr I love my 3" stainless exhaust. Not sure why people get in a pissing contest over who made the better decision on how they spent their money. If chose to spend a grand on a catback exhaust or go just do a cheap muffler delete well that's your God given choice. So be happy with what you have.

I didn't have a brand new Camaro when I was 16. I had to wait until I could buy it myself.

I'm not sure you should start tampering with your car until you can afford the repairs out of your own pocket should something break. However, I agree with an earlier post that you should invest in LTs and high flow cats; you'll appreciate what they can do for you more.

The factory exhaust is not as restrictive as most people think. Sound is the only downfall to it. A muffler delete with xpipe is an easy cost effective way to solve that issue. Some of you guys feel that is cheap way of doing things, all I have to say is not al of us are high rollers. And imo my Jba high flows xpipe and muffler delete sounds better than anyone I know with a full $$$ catback.
