Engine Custom Cat Back + Maganaflow

Custom Cat Back + Maganaflow

Im thinking about getting a custom catback exhaust. How big should I make the pipes and still try to keep it quiet. Also what is stock pipe size? I plan on using one of these mufflers, just depends on how long I need the tip to be but I'm aiming towards the second one.

are you turbo? im guessing not so if so dont go any bigger than 2 1/4 or else you will lose power.

Stock is 1 7/8".

Not on turbo. I was thinking around 2" too. The muffler has a 2.25" inlet so I guess I have to go for that. Now how long do you think the tip should be?

you dont have to go for 2.25. They should have a nipple of some kind that is 2 on one side and 2.25 on the other.

Ya I know but 2.25" isnt that bad of a size either or is it? Would it make it sound like crap?

I had 2.25" on mine -- had a Mitsu Eclipse guy ask if I had a V6..it's also the sound my uncle wants out of his Jetta. I was happy with it...2.25" catback, resonator and a Larsen (sp?) muffler.

Awesome! I will try to find a shop that does pip bending and get 2.25" done with the magnaflow exhaust.

Before I went turbo I got the AlphaWerks full catback which is 2.25 or 2.5 inch and I noticed a slight drop in power in the low end. However one wierd thing I noticed is that the engine would rev way faster? Has anyone else with a cat back noticed this behavior? When I put it in nutral and rail on the gas the needle jumps really crisp and before I did the exhaust it was kind of laggy.

wait stock pipe size on a 8th gen is 1 7/8?

^^ yeah almost 2 inch

they say when you do an exhaust you lose a little low end and gain it on the top.

2.25 pipe should be fine.

Do 2.25" or just leave it stock. My 0.02

I gotta say that I'm in love with my Magnaflow catback!! I love the sound and the little added boost. I got 2.25" on mine and I think its not too loud either. I have an 03 though so dont know if its going to be different...peace

The AlphaWerks catback exhaust is retarded loud I kind of wish I had of nabbed something a little quieter. I might just swap out the muffler or in this case "Amplifier" for something a litter nicer later on.

I just went out to my car with a ruler and put it up to my stock exhaust and ya I must admit that 4" is too small. The tip would barely reach out of the bumper. 7" should do it for me Now all that's left for me is to find a damn shop that can do pipe bending. I called up this one place I found in the yellow pages that had a big ad that said custom pipe bending up to 3" diameter. I called and he said he can't do it because there isn't anything for me car? The guy barely spoke english so I don't know what he was jabbering about.

I have the Alphawerks on my car at the moment with a Magnaflow, and yes, retarded loud is how I would describe it as well.
