silly question

[Russ_16v]

my ph1 172's exhaust has a slight blow by the rear box,so me thinkin of replacing,now i know it sounds silly but iv not got a great amount of money,so shall i get a std one as the car is std,or shall i go aftermarket?

 

[kully]

just replace the backbox with an aftermarket one , costs are nearly the same , but this way , you can get a stainless steel one .

You'll be better off with a stainless steel one as they cost about the same.

Could try buying a second hand one?

not sure whats best? how much am i looking for an aftermarket box? does the rear section just include the box or does it stretch bk to the cat?

judst a quick question, i have a magnex on the back, mine is stripped and a plug thinggy fell out of the floor in the back, didnt do anythin just there to cover up somthing and now when i open the window it sonds as if its blowing but checked the zaust and its not, is this just the air coming in the windoew and going through this hole (size of a 50p)????

anyone?

 

[matty w]

not much point just changing back box as middle section probably not much better,just get a cat back system if funds allow,peice of mind then isnt it

 

[Russ_16v]

so is the rear box seperate on its own? or is it like the valvers and willys and has a 3 piece system?

 

[msa197]

The exhaust will need to be cut in order to fit the new one, as the original is a one piece that fits over the axle. Or you could drop the axle and remove it in one piece.

reason i aking is i havent had the chance to get it up on the ramp at work but the rear box looks brand new and the blow seams to be comin from the bend just as i goes over the axle?

When my exhaust went on the bend at the back box i just used gum gum paste and a bandage lasted me about a week and a half until my magnex arrived it whould of lasted allot longer just need to add gum gum paste when needs it, depends when your getting more money though?
