Hey Tech, posting this up for my brother. He just bought a 97 z28 and looking to mod it a little. He said he wants a loud exhaust. I owned a ls1 T/A so i know my way around fbodys and told him he would probably like the slp loudmouth. But, slp only makes it for ls1 now and discounted the lt1 adapter.

My question is, what are some good catback exhaust systems that are decently priced and loud/noticeable? I had a magnaflow on my T/A and i liked it but he wants something louder.

 

have him get a magnaflow with a cutout. or get a gmmg

 

Flowmaster or SLP is loudest

 

youtube might help give you some ideas!!! Full length headers , Y-pipe & catback without a cat if you can get away with it!! I like my Mufflex with race muffler

 

SLP Loudmouth or Borla with wide-open plate. Either setup is decently loud on a stock car, and earsplitting if you have headers and off-road pipe.

 

My dads stock LT1 with flowmaster cat back is almost as loud as my head/cam car with headers and no cats. I have magnaflow on mine

 

Add more power. My 2otl is loud as hell at WOT.

 

The 96-97's dont need the LT1 adapter

That said, theres a loudmouth for sale in the classifieds

 

GMMG is SOOO expensive!!! That's what I want... Prob just go with Hooker or dynomax race bullet mufflers

 

Really? Can anyone else confirm this? He may just get the loudmouth in that case.

And thanks everyone for the replies. I talked to him, if he doesn't go loudmouth, he'll go magnaflow with a cut out.

 

x2 I had a borla cat back on my 95 z28 lt1 with wide open plate it was plenty loud. Then added Long tubes and ORY pipe and that really opened it up!

 

I've always been told my car was extremely quiet until I went WOT. The magical mojo powerz of the 2OTL!111

 

The 'LT1 adapter' is the S-pipe that goes from the trans tunnel to the single cat (93-95 cars) under the passenger side hump. 96-97 cars got two cats and each respective outlet merged with an outlet in the same place as the LS1 cars' y-pipe. If its not in the exact same spot, its maybe an inch difference, if that.

Simply tell him to look under the car and he should see the factory band clamp just in front of the 'wavy plate' across the trans tunnel

edit: scroll down and you can see a pic comparing the 93-95 y-pipe to a 96/97 one. The 96/97 one already has the S-pipe that curves around to the trans tunnel.

ok, thanks

He doesn't know anything about working on cars yet, so I'll be doing all the work and hopefully he can learn in the process. After doing some research myself, I did find that the rear hangers are different, so i'll be looking out for those for him.

Thanks again everyone.

 

just the driver side, passenger side is the same

I found the LS1 driver side bracket at a salvage yard for $5 with bolts and rubber hanger

 

Ok cool. I'll be on the look out for the driver side hanger. Thanks again!

 

I'm assuming the driver hanger bracket is the only part he needs? The rubber hanger/bolts/nuts are all generic parts that I can find anywhere in local parts stores?

 

correct. you can reuse the bolts

 

One of my favorite cat backs for a 4th gen.

 

If your brother will end up doing headers and ORY down the road he should consider hooker exhaust with the Aerochamber muffler.

It sounds absolutely wicked from inside and outside the car at WOT, hardly any rasp especially for a chambered muffler and its quiet enough to actually be able to talk to a passenger will cruising on the highway.

It might be a little tame loudness-wise with stock manifolds and cat but still sounds plenty aggressive.

The best part I like about the Aerochamber it my car doesn't sound like a friggin truck!!!
