i think i have my exhaust, tell me what you think!
Sunday, June 19, 2005 2:24 AM
i think i have chosen my 3 items (header, high-flow cat, and catback exhaust) and i need some opinions and feedback, as well as any thoughts or anything i should do diffrent.

if any of you have used these products that would also be great if i could get some advice or ratings.

here is what i got:

for a header i have chosen the OBX racing header...

for more info on this item, check the link:
http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&rd=1&item=7981291456&category=33632



for the high-flow cat, i have chosen the 2.25 inch (inlet and outlet) catco converter....

and for the mandrel bent catback exhaust, i have chosen the megan racing system, which i have heard good things about....

its good because its 2.5 inch piping, then narrows to 2.25 at the cat, so that my catco cat will fit up to it!
more info:

and the last thing is a casper O2 sensor....

I do not recommend the catco converter. I do not have one myself but have heard bad things from others here on the .org. You may want to look at a 2.25" magnaflow high flow cat, you can't go wrong with magnaflow

do not spend $90 on a cat. go to ebay I got my 2.5" magnaflow for $55 shipped. and no you shouldn't need the casper O2 sensor because you will be putting a cat on. i haven't heard to much about the Megan exhaust on J's, nor have I even seen a pic with it, anyone got a picture with this exhaust??

I've heard one bad thing about the Megan cat back system, the hump over the rear axle is not too tall, and if your lowered, or plan on lowering, there could be some rattling/knocking of the tubing on the axle. But that's just what I've heard, other than that it's great.

I bought those OBX R Header off ebay , and it didnt fit right. So back it went. I went with the pacesetter, it fit MUCH better.

theres no point in 2.5 " piping that narrows to 2.25 for the cat....remember....it only flows as well as its narrowest point...might as well get 2.25 piping all around

i found a pacesetter header on ebay i like... does the pacesetter header come with the downpipe that connects to the cat?

and i found this cat on ebay also:
http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&rd=1&item=7977930981&category=33629&sspagename=WD1V

will that cat have to be welded onto the downpipe from the header and then welded to the cat-back piping? why dont any of these cats come with flanges on the end to bolt on to the other exhaust parts?

the downpipe comes with the pacesetter header and the cat will be welded on to it. the catco cat from ebay is 2.25 inside but the ends are big enough to fit around 2.25 piping and the paceseter downpipe

i think im going to actually buy the magnaflow cat and use that.

my plan is to put the header on, and hang the exhaust, then take a shop the cat and have them weld some flanges and bolt it up into thew system.
but would a 2.5 inch cat be able to be custom welded onto the 2.25 flange that the megan catback has?

I never knew Megan Racing made a cat-back system for our cars? Their site must not be up to date then.

Yeah it does look quite nice, in my opinion its wierd that it shrinks to 2.25" near the catalytic converter but not like its unable to be changed. All the power to you man.

the muffler shop told me that i might as well replace my stock cat because with all the 2.25 piping the cat would almost defeat the purpose of doing all that being that the piping going into the cat was also stock size. he said i should get a 2.25 high-flow cat that way theres less of a restriction.

Do not buy or use a catco cat. I work at a autoparts store, and they are a lower line, cheaply made cat. I have had numerous customers come back with problems regarding them. they make your car run like crap, and the catalyst guards inside crack/shatter and everthing inside all falls apart.
hope this helps.

Sorry to jack your thread but just 1 quick simple question, is there anywhere else other than ebay to get the Megan Racing Cat-Back system?

So you are saying any exhaust bigger than your primaries is poinless?

you can still push more volume in a step down or step up (bigger diameter but eith a smaller spot in it) exhaust then a stright diameter (same size completely through it) the difference is it messes with your back pressure
