Tuning what parts fore complete exhaust

[Yaras]

Hello fiat people

I have just bought a GP t-jet 1 month ago amazing car! but i want a little more power nothing crazy but around 30 bhp ore so, so i was thinking a new intercooler (forge) and a complete exhaust system maby super sprint but would that be enough fore 30 bhp gain? The only problem is the exhaust and that's where i am lost i mean really lost :bang: i see so many parts and cant figure out what i need fore a complete exhaust set.So my question is what parts do i need ? any help would be appreciated i don't want to change the turbo as i have read that the vl37 can take about 160 bhp if i am correct ? also do i need to remap the system ? thanks in advanced

Intercooler won't add any bhp, it will just allow you to use the power longer before getting heatsoak and lose power.

The exhaust will probably add a little hp but certainly not 30bhp, maybe 8-10hp?

You may see 30hp if you do these mods and remap too.

de-cat + exhaust + Remp you will get about 30bhp

iirc the tjet has a cat right after the turbo, it might have a main cat too not sure though.
theres a mid box and a back box,
TMC do a precat delete as a direct replacement, if theres a main cat just get an exhaust place to replace with steel pipe,
Could get the mid and back box off only difference will be more noise.

exhaust mods don't make huge gains but are useful on a turbo, the precat is rather restrictive,
160bhp is alright but you want more torque, i raced a tjet with an abarth turbo and had him easily.

vl37 turbo, forge intercooler, decats, an induction kit (a gsr, or a forge are good, they make a difference on this engine, stock airbox is restrictive,) high octane fuel and a custom remap would see you some nice power
