back box

[fd3szhi]

hi people i just got a couple of questions to see what you guys think.
im thinking of going full stainless steel on the exhaust system but i have a pair of jasma back box the box itself is stainless but i dont think the tubing is so the question is then shall i change the back box as well as the other pipes or cut the tubing and weld the proper stuff on.

second question sorry is what shall i go for if i want to go down the 1 box route and i dont mind it being loud.

is it safe to run a decat pipe with out a apexi?

[m1tch]

Running a decat without an aftermarket ECU isn\'t advised, the reducing in back pressure will mean that the turbo spools up easier and will boost creap, if there isn\'t a map for fueling and it over boosts it could go lean and detonate, taking out the engine.

Ooo i know what you mean now so shall i map it 1st then install the decat?
