Japspeed exhaust question

[edt]

Hi - is there a performance gain in fitting something like:

to my Rev 4 NA car?

Straightforward fit?

Are there MOT implications?

You'll need to keep a standard exhaust to swap them over as the Japspeed doesn't have a cat in them and has nowhere for one. You'd be better off spending a bit more and getting the Mongoose instead as it's road legal.

Also the Japspeed is bloody loud by all accounts whereas the Mongoose has a deeper throatier tone to it

You mean swap over come MOT?

[Ryan6926]

Yup, Sorry was on phone didn't flick back through it

Yup, you need a cat for the MOT. The Japspeed bypasses the cat so doesn't have one. So in order to be legal and pass the MOT you'll need to put your standard exhaust on with the cat

IS it a bolts job, or welding needed?

[Ryan6926]

It's a straight bolt on job so nothing too major

If you're fitting the Japspeed then unbolt including the cat. If you can source a Mongoose then I'd go for that as it's not so intrusive and it'll be fairly well priced if you can find a used one

Have to admit I do prefer the OTT look (and sound?) of the Japspeed

After getting the back of the car up on stands, how long a job to swap exhausts over? Need anything more than a socket set?

[Ryan6926]

It depends how rusty the bolts are if it's OEM exhaust already fitted. Grab some Plusgas, soak the bolts previous and it shouldn't take more an an hour or 2 if you leave the bolts soaking for a day or 2

If you've got bolts that really won't come off then you're going to need an angle grinder or similar to heal separate them. You may need an exhaust gasket as well etc
