SLP Ypipe
I'm wanting to upgrade my exhaust but, I'm going to keep the exhaust manifolds. A guy I work with was saying that SLPs y-pipe for manifolds would be alot better than the stock one. I'm just curious what you guys think of it. Also what else can I do. I have a magnaflow muffler on already. Any suggestions would be appreciated.
This is on my 84 firebird with the lg4 305.
Thanks

I like the performance of headers but, I don't like the hassle they cause. I would like to put them on my car but, with it being a daily driver I don't think they would be worth the time and trouble they are.

My SLP install is goin great, and they do a great job of designing headers nowadays so all the stock stuff you want to keep will fit. I really don't think there's much use do doing all the work of swapping out the Y-pipes if you keep the same restrictive manifolds on there. Plus, spark plug changes will be a breeze.

go for the headers. edelbrocks makes a good set that goes in fairly easy. but there are other more popular brands like SLP or Hooker. my car's also a daily driver and i haven't had any problems with burnt wires or loose bolts or anythin like that. only thing i recommend is gettin 'em ceramic coated. it's not that expensive (i was quoted 200 for mine) and am sure well worth it. uncoated header tubes get pretty damn hot.
i doubt you'll feel any improvement in performance with better flowing y pipe and stock manifolds. you will with headers.

I have the SLP Y-Pipe connected to the stock exhaust manifolds and they perform great. I have it connected to a Car-Sound high flow Cat going into a Flowmaster Crossflow muffler. I recently failed the smog test because the technician said the engine (LO3 5 spd) didn't have enough back pressure!
I bought the SLP Y-Pipe because of the same reasons you have and I have never regretted it. Even though the stock exhaust manifolds are restrictive, they are so short that even with just the y-pipe the exhaust flows out a lot smoother. I think it's a great compromise.
