Hooker or TSP headers? Hey guys,
I'm new to this whole thread thing but I'm just looking for some opinions on which headers to get. I just got a 99 z28 with a brand new ls1 engine in it. I recently installed a SLP LM 2 exhaust and I just found out that one of my catalytic converters is bad. Instead of replacing the cat I'm looking to get some LT headers and an ORY to compliment the exhaust. I'm leaning towards the TSP 1 7/8 headers with the TSP ORY to go with it. But I've heard about installment issues with the TSP set-up. I want to stick with the stainless steel but dont want to break the bank either. Do you think this would be a good set-up? And what are your guy's opinions on hooker ceramic coated headers? If I could get some insight that would be great! Thanks

I bought the hooker Lts and y pipe with a loudmouth 2 since then I changed the y pipe to a tsp y pipe and I wish I would have boughten the tsp headers too so I'd say for sure you will be happier with the tsp stuff. When you get that installed you will probably wish you had a different cat back the slp loud mouth is soooo rapy, but maybe you will like that. Good luck!
I have a set of hooker lts on one car and tsp lts on another car. The fitment on the hooker lts is much better, I had to do a lot of prying to get the tsp y pipe to stop rubbing on the floor board and over all they didn't go in as easily as the hookers did.
However I do like that they're stainless and performance wise they are the same.

Thanks for all the advice and opinions, I ended up ordering the Hooker lt's with a TSP catted Y pipe. Now I just have to wait on them to come in... I'll let you know how the installation goes and how I like the set up. Once again thank you

Sorry for starting tjis thread back up but I figured it wasn't started too long ago. I also have an SLP LM system and I was just looking at the TSP LT's and ORY pipe. my only question is, does the ORY pipe have a reducer to go from 3" to 2 1/2"

I'm puzzled as to what you'd need that for? The LM setup has a 3" intermediate pipe. And the TSP ORY is a 3" pipe. And TSP headers have 3" collectors. Where are you needing the reducers at?

I have the catback on my car now but I didn't install it so I am not totally in tune with diameters of all the parts. Where does the system drop down to 2.5"? At least I have read it goes to 2.5". Hope I don't sound ignorant right now.

It's actually 2.75", pretty much all 3" cat backs reduce down to mach up with stock y-pipes and most y-pipes also reduce down to match both stock most aftermarket cat backs. If it was my car I would cut the reducers off of both pieces and have a new longer reducer welded to the y-pipe to remove the restriction. Also if your car is to loud or raspy with the ORY just replace the LM resonator with a Magnaflow, Borla, Dynomax, or other bullet muffler.

My cat back doesn't look like it reduces down because it's actually all 3" tubing but has a short section that is double thick to reduce it's inlet size. Others may be the same.
