My mistake!

mandrel exhaust systems have shitty fitment, i sold mine that i had on. the tc exhaust is about 4 inches or so shorter then the ss/sc exhaust so you have to shop off the flange and have some extra pipe welded on, then id suggest getting rid of the 2 bolt flange on your dp and find another stock 3 bolt flange

if your gonna have them weld on extra piping, why not change the flange on the catback?

I'll probably just cut the flange off the TC exhaust and have a muffler shop extend it and put the correct flange on to bolt up to the ZZP DP.

i had the extra piping welded on my dp, then weld another 3 bolt flange on the dp and ditch the 2 bolt.

I guess the more Of the exhaust that's 3" the better? Also I'm going to assume the 3 bolt flange will work better than 2 bolt. Do you have any pictures of your setup?

the flange on the tc exhaust is a 3" flange i believe so if you buy another flange either stock or from zzp and weld it on to the 3" zzp downpipe after you add the extra piping youll be good. i actually went v-band clamp and ditched flanges all together but the clamp alone was like 100$

anyone have any videos of a LNF catback on a LSJ

Wouldn't it be better to just to the over the axle from CTI to get rid of that restriction area? What is the advantage switching to the TC cat back opposed to keeping what you have and fixing the problem area?

There is a another problem area in the stock LSJ catback, and that's at the inlet of the resonator. I guess you could just swap out the resonater & over axle piping of the stock LSJ catback, and be ok, but if it's cheaper to get the LNF catback I would go that route.

All you would need to swap on the LNF catback to get it to bolt to the SS/SC's downpipe would be the connection flange. That's a pretty simple/cost effective fix to have a 2.5" catback that will fit like stock, and flow better.

because the TC catback is 2.5 all the way back, has a stock resonator with a bigger inlet then the SC catback and a better flowing stock muffler. The SC catback has a small resonator inlet, crimped over the axle portion and an extremely restrictive muffler. The TC could probably be picked up for cheaper then the over the axle portion and would probably yield more gains.

also the TC catback should keep it quieter than replacing all the restrictions in the SC catback

Perfect that seems more effective and efficient. Thank you both Staged and Tarheels

no problem, im seriously considering this but im worried about how the LNF catback would handle my badmab header and 3" CTI catted downpipe, worried about rasp and it being too loud. Any input on this?

Maybe put on a glass pack in place of the resonator? I've read in a couple threads from different people that the glasspacks really keep noise down and don't cause any restrictions. I am wondering myself what to do I have the ZZP LTH and catless dp waiting to be installed but I don't want to mate it with the stock exhaust in fear it will sound like crap.

lol well im hoping it would be not so raspy cuz i dont wanna have to weld in resonators and **** haha hopefully i can just swap it and be done with it. still looking for videos...

I have a TC cat-back on my IRL.

You will need to order a LNF flange from OTTP for your dp or cut off both flanges and weld in a v-band.

I would also highly recommend replacing the LNF Resonator. It is way too small for an SS/SC.

breakdancnkid26

Well whoever had the car before me already cut out the stock resonator and replaced it with a straight pipe. So technically would my stock exhaust now be 2.5" until it gets to the over the axle section?? If that's the case maybe I'll just see which is the cheaper way to go. The CTI over the axle section or the stock LNF catback.

Thanks,
Ryan

Well the CTI over the axle section in 2.5" is $265 plus shipping on OTTP. The full 2.5" catback from mandrel bent exhaust systems was $285 shipped so I would just go that route if I had to. Looks like I'm still going with the LNF catback and swapping out flanges. Might just cut out the stock LNF resonator and run a straight pipe to see how that sounds. I can always add a glasspack or different resonator later if I have to.

Thanks,
Ryan

hows it sound? and what are you running with it?

ebristol

iTrader: (4)

I am running it with a cat-less CTI Mid-length. Its quiter then my old 3" cat-back but not as quite as I wanted. I bought a 24" round muffler to replace the LNF resonator and I have bought a Metal Spun Cat but I have not installed them yet.

As it sits, it is raspy.

Say if I decided to keep the stock TC resonator while putting the TC exhaust on a RL, will I need to lenghthen the mid section to make it fit? Any other modifications that need to be made to make it work?

I had one on my 06 ss/sc. had the flanges converted from the 3 bolt to the 2 bolt lsj. fits on like stock. if the car has a stock manifold and dp....sounds REALLY good. Change the dp though....and for some reason it is loud!

Cheap mod to do if you have access to one. I got rid of mine (its in the back of the shop here at work) because of the noise it made......BLLLLLLLAAAAAAAAh BLLLLLAAAAAAAAAHHH

YouTube - Cobalt SS 2.4L LNF Catback -resonator.

I realize it is a 2.4L but we need someone to post it on the LSJ

Found this thread on a search. I just bought a TC exhaust for my ss sc. Ill post vidz as soon as it's installed. I'll have it running off a BadMab header and stock DP.
