I did the B16 swap on my brother's car last year, and I knew it was only a matter of time before the POS exhaust rusted through. Well, it finally happened, and he pulled a dragging catalytic converter throught the streets of St. Louis for 30 miles last week.

Anyway, he's pieced together a good system, but doesn't know which cat application to use. Here's what he has got so far:

Car: 1993 civic EX coupe w/B16A swap

header: DC 4-2-1 stainless header

exhaust: Magnaflow Stainless 2.25" catback, model 15641

I told him I didn't know which cat to use. He wants a hi-flow that will be the right length and where all the bolt holes will line up correctly. Should he get a del Sol one? RS/LS/GSR integra?

Help us!

he can get a carsound cat for his car and then get a good shop to weld an extension on. its not gonna just bolt up.

yeah just get any high flow cat and go to the muffler shop and extend the length. simple, done!

i've heard bad things about carsound cats... anyone have a valid experience with them?

i have done many b series swaps in 92-95 civics and i have found that if you use a 94-2001 integra LS header and CAT then you can retain the 92-95 civic CATBACK system. without having to get anythign welded by a muffler shop. i had to di this many times all i did was unbolt the stock EG cat and bolt on teh LS CAT and then bolt up the LS HEADER. so in reality u can get a after market LS header and LA CAT and should not have to go to a mufler shop.

hope that helps

We've had the same Carsound on 3 different cars so far for almost 4 years, and no complaints at all.

thanks nextelbuddy, that helps alot. it's exactly what I was looking for.

We had thought about doing the muffler shop thing, but it just didn't make sense to have get a full stainless steel sytem and then pay a muffler shop to weld in a small section of mild steel that will rust out in 2 yrs with the midwest road salt he drives in.

also, will a 94+ LS header hang a little lower than a B16A one due to deck height differences? I know I'd heard that about GSR/ITR headers on B16s. My brother's car is lowered a little, so the header might be the first part to contact the road.

Also, you're saying the exh mani flange bolt pattern is the same on an LS as a VTEC header right?
