Hooker Sidepipe - Glasspack vs. Reverse Flow?
I am looking into getting some hooker sidepipes for her so she can sound meaner than she is. I am looking at going with a complete hooker setup even though I have seen some people go with other brands for the side pipes and mufflers. I have two options for the muffler inserts, reverse flow or glasspack. Whats the differences in sound and performance? I guess performance isn't a huge issue since they are easily removeable for racing?
And, while we're on it, why wouldn't I use hooker for the pipes and mufflers and what are the other options?
And, this little guy made me yawn: :yawn:

I lost 96 hp with the reverse flows. See my dyno chart at spiralturbospecialties.com. Get the JCL baffles, do not even bother with the Hooker mufflers. :iagree:

I am another "convert" to the JCL inserts. I had the Hooker glasspacks in mine for all of 40 miles. Absolutely _killed_ power...and I have a mild BB. If your SB is bone stock, then it may not be a big deal, but I would not label either of the Hooker muffler offerings as "performance-oriented".
I took mine out and ran open pipes and got all my power back...til it just drove me nuts, and then I installed the JCLs. I can't tell of any power loss compared to open pipes. I'm sure there was some but minimal. With the Hooker glasspacks, the engine almost wouldn't rev under load past 4000rpm.
As far as the Hookers or any baffle/muffler/insert being "easily removeable for racing"... that's a crock. I've had my sidetubes off twice now and its a PITA compared to what it looks like the job should be.
Do it once, do it right and get the Hooker headers and sidetubes and then get the JCL baffles. :D

The reverse flow are quiet and are extremely restrictive.
The glasspacks are a bit louder and are very restrictive.
If your motor is stock and you plan on keeping it that way, the glasspacks will probably not cost you much, if any HP. The problem is that the glasspack have a 1 3/4" - 2" inner diameter with a louvered core. A louvered core is where the "holes" are created and the metal is angled into the pipe. This effectively makes the inner diameter smaller.
Look at the motors those guys have who lost 95 HP. They have almost 50% more displacement than you.
If you are a little creative or can find a creative muffler shop, you can modify some better glasspack inserts (Thrush) or auger style to work and you will get out for less money than the Hooker ($140) or the JCL ($300).

Re: Hooker Sidepipe - Glasspack vs. Reverse Flow? (BeaterShark)
Right now I am bone stock, but the plan is to change that. I want to add the sidepipes, upgrade my tires, suspension and brakes, and then I'll have a good house for a better engine.
Looks like JCL is the clear favorite.

Re: Hooker Sidepipe - Glasspack vs. Reverse Flow? (pingdashf)
I'm runnin open pipes.. but they are a little bit on the loud side..
The best muffler on the market are definetely the JCL's STS Baffles...especially if uncapped

JCLs here... Had both teh glasspack and Reverseflows. the Reverse flows are OK if you have lower HP... reverse flows suck in all cases.. Car sounds like a minivan..

Of course, that doesn't make SOUNDING like one any more justifiable.

Problem is that those JCL baffles are expensive.

Re: Hooker Sidepipe - Glasspack vs. Reverse Flow? (Chuck Harmon)
Loud, inexpensive mufflers would save me money but would lose me a whole lot of horse power.
Sure it takes some effort to find the ones you want and then more effort to get them in the side tubes, but it also takes some effort to swap cams and you wont see me paying someone to do that.
IMHO, if you're willing to spend the money and you don't want to deal with the work required in getting free-flowing mufflers in the side tubes, go with the JCL's. But to think that is the ONLY way to get performance out of Hooker side pipes is just not true.

I bought JCL baffles and side pipes. Quality is first rate and they fit perfect. I am using Stahl headers and am impressed with the quality and fit of those as well.

I dissagree with this statement. Perferated core glasspack mufflers are really hard to beat for performance. After all, this is what most "racing" bullet mufflers are.

I also disagree. Yes, you can install perforated glass packs that will be just as free flowing (3" clear inside diameter), BUT, they are MUCH louder than the JCL's.
