Hey Guys,
I am about to upgrade my very stock car (right now all i have is a Borla, and some intake and suspension mods, and a bunch of appearance stuff ) to Heads, Cam, Pacesetter Coated LTs, Ported TB, ASP pulley, Torque Arm, Drag Radials, and a BUNCH of other stuff. My question however, concerns the Y pipe though. I have two of them sitting here right now, and I am torn between whether to use the offroad Y pipe that came with my LTs, or a Mufflex catted Y pipe that I bought for Jet Hot LTs (Has High flow carsound cats on it). My questions are:

1. Will a Mufflex Y pipe that is meant for Jet hot LTs even work with the Pacesetters? (meaning, is using that Ypipe even an option?) Im not sure if the headers are the exact design and if it will work with my Pacesetters and Borla...

2. Some people tell me that LTs, an offroad pipe and a cam sounds absolutely wicked. Others tell me it is WAY to loud, and as a car that gets driven alot at night and on the highways, will have way to much drone for my taste. I will be running my Borla closed (electric cutout) when I need it quieter, but if the car is still unbelievably loud I may consider using the catted Ypipe to quiet it down just a liiiiiiiiiiitle. I bring my car home to a quiet apartment complex at 12-1AM almost every night, and if that setup is going to get alot of complaints i will definitely go with the catted one (depending on question one however, if that Ypipe will even fit.. )

3. Do any of you have either of the setups listed that could fill me on the noise, driveability, smell and other factors that my GF, neighbor, etc. could complain about. I have never done LTs before so im really unsure over which way I want to set this exhaust up. LTs, Catted Y to a Borla VS. LTs Offroad Pipe to a Borla.

Any help, advice, oppinions would be appreciated ALOT! Thanks guys.

 

^ Oh by the way, (to give you a background on my new setup i mentioned) i just bought Futral Stage II heads and an FM15 Ron Jeremy Cam so I am aware that the setup will be ALOT louder and lopey (my car is pretty damn quiet now with only a catback), but thats why this question is important. If a catted y pipe will help with the noise alot, and that Mufflex one i have will work (question 1), that is the route i willl take. I am really worried about not being able to drive this car at night anymore with that heads/cam and exhaust setup so I need some advice.

 

pacesetters and jet hots are the same design soo the y pipe should be the same and as far as noise is concerned the cats would take out some rasp and drone but thats about all i can give u since i dont have a cam in my car but my car with lts a cutout and a ory isnt even as loud at low rpms as it was with stock manifolds and a cutout

 

THanks bud, anyone else have experience/advice on this?

 

theres a guy in my area that has pacesetters lt's ory thr a loudmouth, plus a cam and it is very loud even at idle

 

qtps with catted y, sounded good, then one of my cats blew out, so i just gutted the other one. with the corsa muffler the car is not too loud. with the borla you can away with comming home late, where in nj do you live? north jersey here, if your local i can show you my car with the gutted cats.

 

Hey thanks for the replies guys. Im in Northern NJ too, up towards Hackettstown/Island Dragway if you have ever heard of it?

I am still undecided about this. I bring my car home to a quiet neighborhood almost every night, and I dont want it to be so loud I am afraid to start it if I feel like a coffee run at 11PM. lol. Sacrificing 5-10RWHP by running High flow cats absolutely sucks, but it may be a compromise im going to make.

 

check your PM

 

I love how the catted Y's and h/c car sounds (mine especially) but i just blew a cat 3 days ago as well. Chances are, with what you are doing...you will blow your cats. ORY pipe will be better IMO and more hp/less headache..BUT it will be louder and you will get rasp. I suggest ORY with a quiet catback.
Good luck with whatever you do

 

Keep the cats.

 

I have LTs w/ an ORY and the LM. All I can say is it is loud as hell...sounds like a race car at WOT. And its really raspy.

 

I think i may stick with the high flow catted Y pipe. Id like to be able to start my car late at night without waking EVERYONE up, as im sure the setup with an offroad pipe would.

Thanks for the advice/oppinions thus far guys.
