I'm trying to figure out which cat-back I should go with. My girlfriend is currently driving my camaro cause she can't drive my 5 speed maxima so my camaro is a weekend car. I'm looking for something that is loud but not too loud. I don't want anything loud enough to get her pulled over. She likes the flowmaster but I know that's one of the most restrictive cat-backs you can get. She's all about sound and i'm all about performance. I know the slp loudmouth is the least restrictive in my price range but is also one of the loudest. I also plan on doing headers and ORY eventually so I don't think the loudmouth will work. I read that the loudmouth 2 isn't supposed to be as loud but how is it performance wise? Any suggestions?

 

I'd get the Loudmouth, but if your planning on getting headers soon probably like Corsca or SLP 2OTL

I have a flowmaster 40 under the middle of the car and straight piping out back in the shape of a LM catback, it sounds good but I am sure the 40 series is holding me back (if not yet, it will in the future)

 

I would go with something ilke borla, corsa, or gmmg but they are out of my price range. How is the 2OTL as far as performance?

 

I did a lot of research and chose the hooker cat back system. Its quiet at idle and driving around but sounds really good at wot!

 

How restrictive is the hooker compared to the loudmouth ll?

 

Not sure on the restrictiveness of the hooker, but I have it and LOVE it.

 

FWIW, My car has outrun many with similar mods ... And I am using a "restrictive" flowmaster ... Yes they are not as straight through as other designs. But NO you WONT notice the difference. Back to back dyno results, on more than one occasion on here, with a few different people have shown 2-3RWHP differences. This is negligable.

You could strap your car down, make a run, and put down 300RWHP. Then 5 minutes later make another run and make 295RWHP because its getting a little warm, etc. etc.

I noticed a SOTP difference in throttle responce putting my flowmaster on it. Had I bought a cat-back, I would have likely went with either a Magna flow or a Hooker. I can say this, my Flowmaster is pretty tame sounding at idle. Under any load though my car sounds like it wants to rip someones ****ing head off.

Why dont you go with a flowmaster, then once you mod it more ( Headers, ORY etc. ) throw a E-Cutout on it. Then its quiet enough for when you see the local law enforcement, but when you want performance, its flwoing better than true duals ...

 

I thought about doing the flowmaster and then doing the headers and ORY with a cutout but that won't be happening for a while. Don't get me wrong I also love the sound the flowmaster puts out but then again I want as much performance as I can get for the cash and from what i've read, the loudmouth gives the best performance gains out of any cat-back for the price. It may just be too loud for what i'm looking for.

 

Magnaflow?

Not horrendously loud, can be had for about $280 shipped, and made out of stainless. What's not to like?

 

I believe Hooker has one of the best dyno results.

 

What about Pacesetters? Anybody know much about them?

 

I like LOUD so you might want to just ignore my opinion. But I love my SLP Loudmouth. I was running SLP shorties with high flow cats and the SLP Loudmouth. Everywhere I went I got compliments about the sound of the exhaust. It wasn't quiet by any means. My buddy has SLP Loudmouth on his LS1 and it sounds good but wasn't as loud as mine. I would say the only other exhaust I have heard that I liked as much as the LM would be borla. Borla is pricey but it sounds good and its kinda neat you can put the plates in depending on how loud you want it to be. I am getting ready to run LT's with an ORY into my Loudmouth with a nice cam so it should be interesting. Cant wait to hear her roar!

 

agreed me and my brother got ours for 285 shipped.

 

Buy the one you like the sound of, this "restrictive" catback stuff is nonsense between the popular aftermarket setups... You're looking at very miniscule differences between any of them.

I've got the Magnaflow catback and would recommend it, sounds great w/ my shorties and gutted cat. It's also the cheapest catback that is stainless, the other affordable systems are not unless I'm mistaken. I've also had the Hooker catback on my last thirdgen, and it was also an excellent sounding catback for cheap IMO.

 

I'm want to try something chambered 1 day. GMMG prices are just plain rediculous so I may go with some Sweet Thunders.
