WL alloytec 175KW cat back advice

[ha_almajed]

hi everyone,

I drive a 3.6 alloytec V6 175KW...

I need advice, I was thinking of changing my exhaust system, but i'm not sure how many inches i choose, 2.25", 2.50", or 3"

without loosing the back pressure, and with a nice sound,

i was searching too much for this issue, every one has a diffrent opinion

thanks

From what ive heard mate, twin 2.25", twin 2.5, or single 3".
Yours being a 175 prob the twin 2.25" would be best. I know with the Alloytech 190, you can get away with twin 2.5" & single 3".

thanks mate,

but i'm thinking of a singel one, and 3" for me will be too much i guess,

so .... dont know...

ive only heard single 2.5's sound bad

guys, you are making me more confused, anyone tried single 2.5" on alloytec 175 before?

twin 2.5inch is about the same flow as a single 3.5inch...

twin 2.25inch is about the same as a single 3inch...

[ha_almajed]

ok, if i want to make it a single 3" , what about the catalytics, should i change them as well? what is the app. size for them?

[ha_almajed]

guys, is it ok with custom made catback?

ive only heard single 2.5's sound bad

the only ones that sound bad are done by exhaust shops that have no idea...

done correctly a single 2.5 will sound very good and not drone or sound like a wet fart

I thought the WL series came standard with the 190 alloytech V6!

Dear Dale@CHE, i have two MAGNAFLOW 2.5' middle and rear mufflers, and i'll make the piping in a specialist shop, do you think the sound will be OK? and what about the catalytic converters? should i change them as well? what is the size?


My WL is 175KW , you know mate i'm from BAHRAIN, Bahrain - Wikipedia, the free encyclopedia, we've never seen a 190KW at all in the ArabianGulf.

guys, HELP i'm confused,
