10000rpm Posted September 3, 2014 Share Posted September 3, 2014 Just on the exhaust point, does anyone else have a tegiwa 2.5" decat fitted as mine no matter what I do Donut ring size wont seem to seal correctly im thinking of getting it welded directly to the Manifold as it is adjustable it slides off anyway, when I have an MOT I swap the Standard mani and cat back on to save Hassle and standard ECU.Hi Jim, I have had the same problem with three tegiwa decats. It's like the flange has been welded on at an angle and not straight. Quote Link to comment Share on other sites More sharing options...
Guest jimbob738 Posted September 3, 2014 Share Posted September 3, 2014 Yeah what a piece of sh1t, I previously used Japspeed ones they sealed fine, what do you suggest mate? sitting at lights the fumes are gasing me out and pretty sure its not helping with back pressure (velocity) tegiwa stuff is dog sh1te I have found that its badly manufactured never a straight fit. I even bought one of there donut gaskets when I bought the decat and its bigger then 2.5" like waving a stick in the albert hall as to its sealing abilities.

It's like the flange has been welded on at an angle and not straight. I find that its positioned too far forwards so that the Flanged wont pull up to the Manifold flange using the spring bolts its just not a nice tight fit so I tried using RVT sealant which doesn't help just compounds the issue now its blowing.

I would personally buy that instead of welding it to the manifold. Quote Link to comment Share on other sites More sharing options...
Guest jimbob738 Posted September 3, 2014 Share Posted September 3, 2014 Yeah it does, suppose its less hassle as it is removable, what did you do with the Tegiwa Decats? what's your opinion on sports Catalytic convertors? Quote Link to comment Share on other sites More sharing options...

If you want to free that power, decat is the way forward. The only advantage of the sports cat is it can pass the emissions test for the MOT once really really hot.

Guest jimbob738 Posted September 3, 2014 Share Posted September 3, 2014 Yeah thought that was the case with sports cats I was just curious of your opinion. Quote Link to comment Share on other sites More sharing options...
