Cat delete gains

gordyordy · 01-24-2011, 09:51 PM

My supra is a 87 7mge non turbo...I live in oly washington so I'm not worried about emission problems. I want to delete my cat...where do I find a tube to replace it? Should I install it myself? How much would it be if I had the shop install it?

On your 7mge without a cat you may actually lose some power since the main gains are on the 7mgte that is turbo and does not need backpressure like a 7mge does.

used to have headers and full 3 inch on my 7mge with no cat.

sounded sexy, and with the headers i felt a good difference...
if your not going for many other AM parts slightly smaller woulnt not hurt maby a 2.5 or 2&3/4 would be perfect

No 7M-GE sounds sexy with that kind of setup.... sounds more like a Civic with straight pipe after getting fisted.

no a civic will have a 1&3/4 inch to a 4 inch muffler haha

what if i just put headers on it? would it sound as sexy?

I don't think the sound changes that much with the header atleast not for me. The problem is that there are only 2 headers made for the 7mge and they are basically the same just made from different materials. Pacesetter and obx are the 2 and they are so so. Both will have to be modified to fit, o2 sensor moved and either wraped or ceramic coated to reduce under hood temps.
